The Importance of Contrast Sensitivity In Baseball

Playing Baseball with Contrast SensitivityBaseball players train hard to develop muscular strength and endurance, but did you know that sharp vision and strong visual skills can be just as crucial to your game?

Winning at baseball requires split-second calculations. When a ball spins toward you at lightning speed, figuring out what kind of pitch is approaching can be the difference between a strike and a home run.

The longer it takes you to identify the pitch, the harder it is to hit it, no matter how well-developed your swinging technique is.

To identify the pitch, baseball players need excellent contrast sensitivity. This is the visual skill that enables you to quickly see the ball’s red seams as the white ball approaches — and decide if it’s a knuckleball, fastball or slider.

What Is Contrast Sensitivity and How Can It Make You a Winner?

Contrast sensitivity is the ability to distinguish between an object and its background. It’s a crucial visual skill, because no matter how strong you swing, or how fast you run, your ability to hit that home run is impacted if you can’t distinguish the ball from a cloudy sky, or the red seams from the white part of a moving baseball.

How Baseball Vision Training Can Be a Game Changer

One way you can go from being a good ball player to an outstanding one is to improve your contrast sensitivity. This means adding sports vision training to your regimen.

At The Scott Eye Care Sports Vision Center in Oswego we’ll custom-design a program to develop your contrast sensitivity. We’ll begin with a functional eye exam to assess your contrast sensitivity and the other visual skills needed to successfully play baseball.

Sports vision training involves eye exercises that teach the eyes and brain to work together more quickly and efficiently. You’ll meet with us for in-clinic sessions and continue training exercises at home.

See the ball more accurately and be ready to hit it out of the park! Talk to us at The Scott Eye Care Sports Vision Center and find out how sports vision training can make all the difference in your game.

Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

 

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: How is contrast sensitivity measured?

A: One way to determine contrast sensitivity is through a Pelli-Robson test, which is like a regular eye chart but one that features rows of dark letters that gradually get lighter. Wave grating is another type of contrast sensitivity test and requires you to identify shapes at different spatial frequencies and levels of contrast.

Q: What other visual skills are important for baseball?

A: In addition to contrast sensitivity, the following visual skills can improve your baseball game:

  • Focusing – keeping your eye on the ball
  • Eye teaming – the eyes’ ability to work together to keep track of movements on the field
  • Peripheral vision –detecting activity, such as a player stealing a base, on the edges of your visual field
  • Visual processing – detecting and interpreting visual information so you can hit or catch the ball

Are Children with IEPs More Likely to Have Vision Problems?

Children with IEPs 640×350Children with IEPs — school-based Individualized Educational Programs — are more likely to experience problems with their eyes, especially their visual skills. Visual skills include the eye’s ability to focus and track and work as a team, but these and many other visual difficulties aren’t detected in traditional vision screenings.

Children with IEPs may pass the standard 20/20 sight test administered in schools. However, the results of these basic screenings aren’t a reliable indication of a child’s ability to perform activities involving close vision, such as reading, writing or solving puzzles.

Even a child with 20/20 vision may have visual deficits that need to be treated, such as lazy eyes or difficulties with visual processing.

While basic school vision screenings assess eyesight, only a comprehensive developmental eye exam can assess visual system deficits or dysfunction that can impede performance in school and while playing sports.

Why is a Comprehensive Eye Exam Crucial for Children with IEPs?

Many children diagnosed with a learning disability may actually have an undiagnosed visual deficit that is causing their reading and learning difficulties—or at least contributing to them.

A 2018 study published in the Journal of the American Medical Association found that 80% of children with reading difficulties had vision problems, compared to children who read at grade level.

In a 2012 Ohio State study, 69% of children with IEPs passed traditional eyesight tests. The reason: basic eyesight tests evaluate a child’s ability to see distant letters and objects, but don’t assess how well they see near objects or letters at reading distance, such as in a workbook.

The researchers recommended that children with IEPs undergo a comprehensive eye exam, which includes an assessment of their visual skills.

What Does a Comprehensive Eye Exam Assess?

A comprehensive eye exam evaluates three main types of visual skills:

  • Binocular vision – the eyes’ ability to work together as a team
  • Oculomotor – the eyes’ ability to track objects and move effectively
  • Accommodation – the eyes’ ability to change focus from near to far

A comprehensive eye exam can detect the following conditions and more:

  • Convergence insufficiency – the eyes’ inability to work together to focus on nearby objects
  • Strabismus/eye turn – each eye points in a different direction due to eye misalignment
  • Amblyopia/lazy eye – one eye is considerably weaker than the other
  • Accommodative dysfunction – an eye-focusing problem

What Does a Comprehensive Eye Exam Involve?

A comprehensive eye exam is designed to measure more than visual acuity and can evaluate overall eye health, diagnose eye conditions and test how your eyes work together. It may include the following:

  • Visual acuity – tests the clarity of sight
  • Cover test – evaluates individual eye functioning
  • Slit lamp – examines the front of the eye
  • Pupil dilation – looks at eye health
  • Retinoscopy – measures refractive errors
  • Refraction – assesses for nearsightedness, farsightedness, astigmatism
  • Visual skills – tests how well the eyes function together

How Vision Therapy Can Help IEP Children with Vision Problems

Vision therapy is a customized program of eye exercises that improves visual skills, strengthens eye muscles as well as the way the eyes and brain communicate and work together. The activities can be integrated into an IEP program to suit a child’s individualized learning program and visual needs.

Vision therapy helps kids improve their vision because it trains their eyes to:

  • Track – fixate on objects visually
  • Team – ensuring the eyes work together
  • Focus – see objects comfortably and clearly all the time

If your child has an IEP, schedule a comprehensive vision exam by contacting Developmental Vision Center in Oswego today.

Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

 

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: How can vision problems affect a student’s educational performance?

A: If your child struggles to read or keep up with their classmates, they may have an undetected visual problem. Reading fluency and comprehension are dependent on the strength of visual skills— especially focusing, binocular vision, convergence, saccades, and visual fixation. A customized program of vision therapy can help strengthen these lagging skills and improve their academic performance.

Q: How do vision problems affect behavior?

A: Behavioral problems that can arise due to vision problems include hyperactivity, inattentiveness, lack of motivation, refusal or hesitation to do homework, poor reading comprehension, skips lines or words when reading, and frequent eye rubbing and head tilting.

If a child displays any of the above symptoms, call ​​Developmental Vision Center in Oswego to schedule a functional visual evaluation.

Everything You Need To Know About Keratoconus

Woman with KeratoconusIf you’ve been diagnosed with keratoconus, our Oswego eye doctors understand your challenge and are here to help you see clearly and comfortably.

Below are some of the most commonly asked questions to help you gain a better understanding of what keratoconus is and how it can be treated.

What is Keratoconus?

Keratoconus affects about 1 in every 2,000 people. This progressive eye disease impacts the shape of the cornea, weakening it and causing it to thin and bulge outward into a cone shape.

The cornea is the clear, dome-shaped outer covering of the eye. It’s responsible for focusing incoming light onto the retina at the back of the eye to enable clear vision. So, when keratoconus develops, the change in the cornea’s shape directly impacts the way light is focused.

Keratoconus often results in nearsightedness and high levels of astigmatism — two refractive errors that cause blurry and distorted vision.

If left untreated, keratoconus can lead to permanent corneal damage and even loss of vision.

What Typically Causes Keratoconus?

Keratoconus develops when the collagen fibers that support the cornea begin to weaken. While having a family member with the disease is a significant risk factor, the following conditions can also lead to keratoconus:

  • Eye trauma
  • Eye allergies
  • Excessive eye rubbing
  • Certain eye diseases
  • Marfan syndrome
  • Ehlers-Danlos syndrome
  • Down syndrome
  • Osteogenesis imperfecta
  • Addison’s disease
  • Leber’s congenital amaurosis

The Signs & Symptoms of Keratoconus

The symptoms of keratoconus include:

  • Blurry vision
  • Distorted vision, with straight lines appearing bent or wavy
  • Sensitivity to bright light and glare
  • Red and irritated eyes
  • Increasing difficulty wearing standard contact lenses

Keratoconus tends to be initially detected in teens or young adults in their 20s, but symptoms can develop at any age.

Keratoconus symptoms usually start out mild but grow progressively worse over time — often over a decade or two — until the condition plateaus.

Both eyes are usually affected, and it’s common to have a difference in optical prescriptions between each eye.

Can Keratoconus Cause Vision Loss?

Keratoconus progression causes nearsightedness, astigmatism and visual distortions to worsen.

Eventually, corneal swelling can lead to scarring of the corneal tissue, which diminishes its transparency and increases your risk of vision loss.

Early detection and treatment of this condition are therefore critical for preventing permanent vision loss.

Can Keratoconus Be Corrected?

Initially, blurry and distorted vision can be corrected with custom-fit soft contact lenses or eyeglasses. However, as the condition progresses and your cornea becomes increasingly cone-shaped, these standard methods of vision correction become less effective.

At this point, many patients with mild to moderate keratoconus opt for scleral lenses, an effective, non-surgical method of achieving clear vision.

Severe keratoconus may require a corneal transplant procedure to replace your damaged cornea with a healthy donor cornea.

Scleral Lenses for Keratoconus

Custom designed scleral lenses help patients with corneal irregularities achieve dramatic improvements in visual acuity and comfort. Scleral lenses vault over the cornea and rest on the sclera while avoiding the diseased cornea. This creates a new optical surface instead of the damaged cornea and prevents discomfort by resting on the sclera of the eye. Moreover, the reservoir of pure saline solution between the back surface of the lens and the front of the cornea ensures that the eye is always in a liquid environment – making it optimal for healing.

Don’t let keratoconus impact your quality of life. We can help you achieve clear, comfortable vision with scleral contact lenses.

If you or a loved one has been diagnosed with keratoconus, call Specialty Contact Lens Center at Scott Eye Care today to schedule a scleral lens consultation.

Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

 

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What Are the Advantages of Wearing Scleral Lenses?

A: Below are the main benefits of wearing scleral lenses:

  • Scleral lenses are made of high-quality materials, which means they’ll last for the long haul.
  • Their large [size] enables them to stay centered and stable on your eye.
  • The vaulted lens holds hydrating saline solution which creates optimal conditions for ultimate comfort and healing of dry eyes.
  • Because the scleral lenses cover more surface of the eye than traditional lenses, they also help shield the eyes from external irritants.

Q: Are scleral lenses covered by insurance?

A: When it comes to scleral lenses, every insurance company is different. We recommend contacting us or checking with your insurance provider to find out if scleral lenses are covered under your plan.

Can Cataract Surgery Prevent Dementia?

Cataract surgery is a highly successful procedure that removes cataracts, the cloudy formations on the eye’s lens that impair vision.

Now, researchers are discovering that vision loss may be linked to a higher rate of dementia and suggest that restoring clear vision (through cataract surgery, for example) may reduce the risk of developing dementia.

Is There a Correlation Between Cataracts and Dementia?

More than half of those 80 or older have had at least one cataract. Many people in this age range also have dementia, a decline in cognitive functioning.

But is there a connection between these two seemingly unrelated conditions?

Recent studies suggest that, yes, there could be a link. One 15-year study found that patients with age-related vision problems, including cataracts, had a higher incidence of dementia.

The 2021 study, published in the British Journal of Ophthalmology, followed 12,000 subjects aged 55-73. When compared to patients with healthy vision, cataract patients had an 11% higher incidence of dementia.

Can Cataract Surgery Prevent Dementia?

Can sight-saving cataract surgery reduce your risk of dementia? It certainly looks promising!

A 2022 study published in JAMA Internal Medicine found that removing cataracts was “significantly associated with a lower risk of dementia development.” In fact, patients who had undergone cataract surgery had a 29% lower rate of dementia.

In addition, MRI scans have shown greater brain activity following cataract surgery.

How Can Vision Loss Cause Dementia?

Scientists studying the link between vision loss and dementia suspect that vision loss negatively impacts the brain. They theorize that the more visual information we receive, the more active our brains are, and brain activity may be able to fend off dementia.

For this reason, by restoring clear vision, cataract surgery may stimulate the brain and prevent cognitive decline.

There could be an emotional and social dimension to cognitive decline as well. People who suffer from significant vision loss often feel isolated. They may feel discouraged by their inability to recognize faces or perform everyday tasks, and may avoid social interactions. According to the Centers for Disease Control, social isolation raises the risk of developing dementia by 50%.

If you have cataracts and you feel your quality of life is affected, schedule an appointment with Scott Eye Care in Oswego without delay. We’ll answer your questions about cataract surgery and ensure you receive optimal treatment.

Q&A With Our Optometrist

How is cataract surgery performed?

Cataract surgery is a short 30-40 minute procedure that replaces your cloudy, natural lens with a synthetic intraocular lens (IOL). First, the eye surgeon makes a hole in the cloudy lens and breaks it into tiny pieces. Next, the eye surgeon places the new clear lens onto the eye. You’ll be conscious throughout the surgery. The surgery is safe, effective and painless.

Is cataract surgery always successful?

Cataract surgery is highly successful, with a 99% success rate. Complications from cataract surgery are very rare.

What Type of Sunglasses Are Best For People With Low Vision?

Three elderly women wearing sunglasses

While everyone should wear sunglasses that block 100% of the sun’s harmful UV rays, those with low vision greatly benefit from the sunglasses’ decreased glare and improved contrast and clarity.

Below are a few things to consider when selecting glasses if you have low vision.

Low Vision Protection From the Sun

The first and most crucial feature to look for in sunglasses are lenses that provide 100% UV-A and UV-B protection. Your eyelids, cornea, lens, and certain sections of the retina can all be damaged by ultraviolet light.

Don’t buy sunglasses if the label doesn’t say 100% UV Protection against both UVA and UVB’ or 100% protection against UV 400. Consider purchasing wrap-around or tight-fitting sunglasses that don’t allow UV light to reach your eyes from the sides or the top of the glasses.

Visibility

Many people often believe that darker lenses equal better protection. In fact, darker lenses don’t necessarily provide better protection and may even reduce visibility, especially for people with eye conditions like glaucoma. Before purchasing sunglasses, discuss the optimal lens darkness with your low-vision eye doctor. Then try a variety of lens shades in the office to see which ones provide the most visibility and comfort.

Lens Glare

Glare sensitivity is a symptom of macular degeneration and many other eye conditions. Even when sitting in the shade, the sun can reflect off the water, the road, a car’s hood and other surfaces, creating a harsh glare. Polarized sunglass lenses decrease the glare reflected off these and other surfaces. This results in increased comfort, improved clarity and reduced eye fatigue.

Vision Clarity

Since macular degeneration reduces one’s sharp vision, wearing sunglasses with high-quality lenses is critical. The clarity of the lens is determined by the quality of the lens material. When trying on the lenses, ask the staff to get you the clearest sunglass lenses they have.

Enhanced Contrast

People with low vision struggle to distinguish contrast. Fortunately, certain tinted lenses provide improved contrast. These include orange and yellow lenses.

So before you select your new pair of sunglasses, make sure to wear them outside and see whether they provide optical clarity, decreased glare, and improved contrast.

If you or a loved one has low vision, contact Low Vision of Fox Valley to discuss which sunglasses are right for you.

Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

 

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What is low vision?

  • A: Low vision is an eye condition that cannot be corrected with conventional eyeglasses, contact lenses or surgery. It includes eye conditions like macular degeneration, cataracts, glaucoma and diabetic retinopathy.

Q: Why is UV protection important for low vision patients?

  • A: Sunglasses may help people with low vision prevent future vision loss caused by UV radiation exposure.

Can We Stop Myopia From Progressing?

boy and a girl with myopiaIf you think more powerful prescription glasses are the right solution to keep your child’s myopia from getting worse, think again. Talk to us about myopia management, which can slow the progression of myopia (nearsightedness) by up to 78%.

How Does Myopia Worsen?

In nearsighted people, the cornea, the clear outer layer of the eye, is more curved than in non-myopes. This elongated eyeball shape refracts incoming light in front of the retina rather than directly on it. The result? Blurred vision.

In other words, the longer the eyeball, the more severe the myopia.

The following can contribute to myopia progression:

  • Eye growth – as children grow, so do the eyeballs. And in certain cases, they become elongated (myopia).
  • Hereditary factors – if one or both parents have myopia, the condition is likely to progress at a rapid pace.
  • Not enough outdoor time –1 to 2 hours a day outdoors is recommended to prevent myopia progression.
  • Excessive screen time – myopia development and progression have been linked to extended screen time.

What Is Myopia Management?

Myopia management is a custom-designed treatment plan that identifies slows or stops myopia progression. Our optometrists provide diagnostic eye exams and create a myopia management program to keep your child’s nearsightedness in check.

Why Is Myopia Management Important?

Myopia doesn’t just affect your child’s ability to see distant objects; it can increase your child’s risk of developing these serious eye problems in adulthood:

  • Glaucoma
  • Cataracts
  • Myopia macular degeneration
  • Retinal detachment

The sooner your child begins myopia management, the better the chances of slowing myopia’s progression and reducing the risk of eye diseases later in life.

Myopia Management Can Preserve Your Child’s Vision

If you’re eager to preserve your child’s eyesight now and in the future, myopia management can help. Book an appointment at The Scott Eye Care Myopia Management Center today!

Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: Does screen time affect myopia?

  • A: Yes. In a study published in The Lancet Digital Health (October 2021), an international team of researchers found that at least 3 hours of screen time per day can increase the risk of developing myopia by 30%. Other research suggests that reducing your child’s screen time and encouraging more outdoor activities can prevent myopia and keep it from progressing.

Q: When should one start myopia management?

A: As soon as possible! Research shows that the earlier a child becomes myopic, the faster their myopia will progress. Act quickly if you want to have the greatest impact on slowing myopia progression.

 

June 27 Is National Sunglasses Day!

Monday, Jun 27, 2022 is National Sunglasses Day, so grab your favorite pair of sunnies and celebrate!

Many people think sunglasses are little more than a fashion accessory or a way to minimize glare while driving.

But the truth is that wearing sunglasses is vital if you want to safeguard your eye health and vision.

Why Sunglasses are Important

The number one reason to wear sunglasses is that they prevent ultraviolet (UV) light from entering your eyes.

UV light has been shown to age every part of the eye, from the delicate outer eye tissue to the tiny structures within the eye itself. Chronic UV exposure raises your risk of developing cataracts, age-related macular degeneration and corneal damage.

The skin on your eyelids is the thinnest skin of your body, and UV light exposure can further thin eyelid skin, leading to premature aging and the appearance of dark circles and under-eye bags. Additionally, wearing sunglasses can help prevent wrinkles because you’ll squint less in the sunshine. Who knew sunglasses can be a key player in your anti-aging routine?

Moreover, UV light has been shown to slow the cornea’s ability to heal itself, making sunglasses a medical necessity for people who’ve recently had eye surgery like LASIK, or those who frequently wear contacts (overwearing contacts can irritate the cornea).

Finally, sunglasses are a fun way to show the world your personality and accessorize any outfit.

Activities for National Sunglasses Day

Not sure how to celebrate National Sunglasses Day? Here are a few ideas you may enjoy.

Sport your favorite pair of sunglasses during an outdoor activity, whether it’s a barbecue with friends, a concert at a stadium or time spent in the park.

You can also celebrate National Sunglasses Day by gifting a pair of quality sunglasses to a friend, spouse or child!

No matter how you choose to celebrate National Sunglasses Day, we hope you enjoy and keep your eyes protected.

For all matters related to eye health, ​​Scott Eye Care in Oswego is here for you. Contact our eye doctor today!

FAQ With Our Optometrist

Should kids wear sunglasses?

Yes, children of all ages should wear sunglasses whenever they’re outdoors. In fact, it’s crucial because a child’s crystalline lens within the eye is much more clear than an adult’s, letting more light through. Contact us to learn more about kids’ eye health or to schedule an eye exam.

Can sunglasses block blue light?

Sunglasses with lenses that have a yellowish tint offer the most amount of blue light protection, from the sun and other sources. If you’re interested in blocking the blue light that’s emitted from your digital devices, speak with us to determine if computer glasses are right for you.

What’s The Connection Between Dry Eye And Asthma?

Woman with Dry Eye And AsthmaResearchers have already established several known risk factors for developing dry eye syndrome: the quality of your tears, excessive screen time, air pollution, hormonal fluctuations, aging, certain medications and medical conditions, and even one’s gender (females are more prone).

Here’s another risk factor that’s recently been added to the list: having asthma.

Asthma is a disease of the lungs that affects about 300 million people around the globe. Symptoms include wheezing, chest tightness, coughing and breathlessness.

Fortunately, asthmatic patients are usually able to do the activities they enjoy by taking prescription medications that facilitate easier breathing.

But medical professionals have noticed that individuals taking these medicines, and sometimes even asthmatic patients who don’t, have a higher incidence of dry eye syndrome.

If you have asthma or any other risk factors for dry eye syndrome, let your eye doctor know. The eye care professionals at The Scott Eye Care Dry Eye Center can identify the underlying cause of your dry eye symptoms and provide you with lasting dry eye relief.

What is dry eye syndrome?

Dry eye syndrome occurs when the eyes consistently lack proper lubrication, either due to insufficient tears or tears that lack essential oils.

Here’s a list of the common dry eye symptoms:

  • Burning, gritty or itchy eyes
  • Eye dryness
  • Red or painful eyes
  • Blurred vision
  • Stringy mucus around the eyes
  • Light sensitivity
  • Difficulty or inability to wear contact lenses
  • Feeling that something is stuck in your eye

What Causes Dry Eye Syndrome?

Most cases of dry eye syndrome result from the dysfunction of the meibomian glands in the eyelids, which produce the vital oils needed for healthy tears, and which reduce tear evaporation. But dry eyes can also be caused by some autoimmune diseases, hormone replacement therapy, certain medications and, it appears, asthma or the medications that treat it.

Environmental factors that can bring on dry eye syndrome include exposure to wind or airborne irritants, pollution, infrequent or incomplete blinking (people blink less when they use digital devices), heating, air conditioning and dry weather. Certain makeup products, including mascara, and application methods such as applying makeup on the eyelid margin, can block the glands that lubricate the eyes.

Can Dry Eye Syndrome Be Cured?

There is now a wide range of treatment options that can successfully manage your dry eyes. The key is to allow us to find and target the underlying cause of your condition, so we can create a plan to minimize and sometimes eliminate your dry eye symptoms.

What’s the Link Between Asthma and Dry Eye Syndrome?

Several studies have examined the relationship between asthma and dry eye syndrome and found that although a link exists, researchers aren’t sure exactly why.

One study, published in BMJ Open (2019), found that asthmatic people of Australian, Caucasian and Asian descent have higher rates of dry eye syndrome than those without asthma.

Another study, published in Medicine (2020), established a significant link between asthma and dry eye syndrome, and found that children with asthma tend to have an unstable tear film — a common cause of dry eyes.

One hypothesis is that asthma medications, like inhaled corticosteroids, oral antihistamines and leukotriene receptor antagonists may contribute to eye dryness by inhibiting tear production, but further research is needed.

Could asthma itself be the culprit? Possibly, but more research is needed for a better understanding. What is known, however, is that having low blood oxygen levels caused by severe asthma can deprive the front section of the eye (the cornea) of oxygen, potentially leading to dry eye syndrome.

What’s the Bottom Line?

Research shows that having asthma may increase your risk of experiencing dry eye symptoms.

If you have asthma, speak with your optometrist about lowering your risk of developing dry eye syndrome and make sure to bring all of your asthma medications to your next eye exam.

If you already have certain symptoms of dry eye syndrome, promptly contact The Scott Eye Care Dry Eye Center to schedule a dry eye consultation. We’ll create a personalized treatment plan so you can enjoy long-term relief.

Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What at-home remedies can relieve dry eye syndrome?

  • A: Make sure to stay hydrated and wear sunglasses whenever outdoors. If you use an indoor heater or air conditioner, direct the airflow away from your face. Use a humidifier at home and at work. You can also try using a warm eye compress. Ask your eye doctor for instructions on how to do so. But keep in mind that trying to manage dry eye syndrome without seeing a dry eye optometrist won’t be as effective.

Q: How is dry eye syndrome treated?

  • A: The type of treatment depends on what’s causing the symptoms. For example, if premature tear evaporation is the problem, your optometrist may prescribe eye drops. Or if your meibomian glands aren’t functioning as they should, unclogging the glands may do the trick. Medicated eye ointment or drops may be prescribed, or we may recommend certain in-office dry eye treatments. Each treatment plan is carefully formulated with your eyes and lifestyle in mind.

4 Facts You Should Know About Scleral Lenses

Woman wearing Scleral Lenses scenic viewDo you have keratoconus or another type of corneal irregularity due to a medical condition or post-surgical complications? Are you considering giving up conventional contacts due to dry eye syndrome?

Consider scleral contact lenses! Contact Scott Eye Care in Oswego to learn more and to discover a new sense of freedom with sclerals!

What Are Scleral Contact Lenses?

Sclerals are customized rigid gas permeable lenses that are wider than conventional lenses. Their name reflects the fact that they vault over the cornea and rest on the sclera, the white part of the eye.

Scleral contact lenses are 14-24 mm in diameter, while regular contacts are 9mm. This gives sclerals room to accommodate irregularly shaped corneas and provides a reservoir of moisture to soothe dry eyes.

4 Essential Facts About Scleral Contact Lenses

1. Sclerals Are the Right Fit for Irregularly Shaped Corneas

Keratoconus, astigmatism and complications from eye surgery can all result in an irregular-shaped cornea, and wearing contact lenses when your eyes are hard to fit can be challenging. Because sclerals are larger than regular contacts and don’t sit on the sensitive cornea, they provide lots of space and a comfortable fit.

2. Scleral Contact Lenses Can Reduce Dry Eye Symptoms

If you have dry eye syndrome, you may be tempted to give up on wearing contacts altogether. Scleral lenses are ideal for people with dry, itchy and irritated eyes. A lubricating pool of saline solution inside each scleral lens can reduce or even eliminate dry eye discomfort.

3. Sclerals Create a Wider Field of Vision

The width of sclerals not only makes them more comfortable but can extend your field of vision. Their diameter can expand your optic zone and make your peripheral vision sharper and clearer.

4. Sclerals Are Durable and Long-Lasting

Rigid gas permeable contact lenses, including scleral lenses, last longer than conventional soft contacts. Their durable materials are designed to resist wear and tear, which is also why scleral lenses don’t require frequent replacements.

Enjoy the convenience and clear vision scleral lenses by scheduling an appointment with Specialty Contact Lens Center at Scott Eye Care and discover whether scleral lenses are the right choice for you.

Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

 

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: Can I exercise with scleral lenses?

  • A: Scleral lenses are ideal for people who lead active lives—whether you’re a professional athlete or just like to pass a ball around with friends at the park. Thanks to their greater width, scleral lenses stay in place on the eye more than standard lenses while simultaneously providing clear crisp vision. That said, scleral lenses aren’t recommended for martial arts and other sports with a higher-than-usual rate of facial injuries.

Q: If I have keratoconus, can I avoid corneal surgery with scleral lenses?

  • A: A study published in the Journal of Ophthalmology (2018) that examined 51 patients with advanced keratoconus found that 40 of them didn’t need surgery after wearing scleral lenses. In fact, wearing them reduced the need for corneal transplant or keratoplasty by half during a 5-year period.

Can a Brain Injury Affect Vision?

Woman with Brain Injury on the CouchIf you’ve been experiencing blurry vision, double vision or other visual symptoms following a car accident, serious fall or blow to the head, it’s almost certainly a result of your traumatic brain injury (TBI). In fact, up to 90% of people with TBIs have disrupted vision that can last days, weeks, months and even years after their accident.

Schedule an appointment with a neuro-optometrist in Low Vision of Fox Valley in Our practice serves patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities. to diagnose and treat the symptoms of post traumatic vision syndrome.

Can a Traumatic Brain Injury Cause Vision Problems?

Concussions and other types of traumatic brain injuries affect 10 million people worldwide every year, with falls, car accidents and sports injuries as its leading causes.

Visual problems caused by traumatic brain injury often go undiagnosed in the rush to treat more urgent injuries, such as a brain bleed or facial lacerations. And in some cases, visual problems may even begin later.

Here’s what we mean by vision problems:

Vision isn’t just about eyesight. For the visual system to work properly, there must be accurate communication between the eyes and the brain. A TBI can damage the neural connections between the eyes and the brain, causing significant visual deficits.

When a fall or other blow to the head causes the soft brain to suddenly impact the hard skull cavity, this violent movement can damage fragile cranial nerves and brain cells, resulting in severe damage. This damage makes it more difficult for neural pathways to transmit clear and accurate messages to the brain and results in a range of debilitating symptoms.

Visual Problems After a Brain Injury

A TBI can cause the following visual symptoms:

  • Blurred vision
  • Double vision
  • Light sensitivity
  • Eye strain

A TBI can also cause problems with visual skills, including:

  • Eye teaming – eyes not working together efficiently
  • Visual acuity – difficulty seeing near or far away objects
  • Focusing – trouble maintaining clear vision or transitioning focus from one object to another

Can I Improve My Vision After a TBI?

If you have post-traumatic vision symptoms, make sure you schedule an appointment with a neuro-optometrist, who will give you an assessment to identify problems and prescribe a neuro-optometric treatment program to improve your vision.

A neuro-optometric treatment program may include:

  • Prism lenses
  • Prescription lenses
  • Neuro-optometric therapy – eye exercises to retrain your eyes, nervous system and brain to communicate effectively
  • Syntonic phototherapy – balances the autonomic nervous system using light therapy.

Q: Can whiplash after a car accident cause vision problems?

  • A: Whiplash occurs when a collision quickly thrusts your neck forward and back. But whiplash doesn’t just affect the neck. It can also impact your brain and cranial nerves. If you have whiplash and are experiencing blurred vision, dizziness or other vision disruptions, schedule an appointment at Low Vision of Fox Valley to see if you can benefit from neuro-optometric therapy.

Q: Can a neuro-optometrist treat vision problems related to vestibular dysfunction?

  • A: Dizziness and motion sickness after head trauma can be the result of vestibular dysfunction, damage to the inner ear and sections of the brain stem. You may experience blurry vision, dizziness, vertigo and lack of coordination. If you have any of these symptoms, contact us at Low Vision of Fox Valley to schedule a neuro-optometric eye exam.
