Why Are Blue Eyes More Sensitive To Light?

Did you know that blue eyes don’t contain any blue pigment? They appear blue due to how the light reacts with the structures of the iris.

In fact, the top layer of a blue iris doesn’t contain any pigment at all. This lack of pigment is the reason that blue-eyed people may be more sensitive to bright light and have a greater need to wear sunglasses than their brown-eyed counterparts.

Why Do Your Eyes Need Sun Protection?

Eyes of all colors need shielding from the sun’s harmful ultraviolet (UV) rays. Exposure to UV light can contribute to the formation of short-term and long-term eye conditions such as corneal sunburn and macular degeneration.

That’s why it’s so important to choose high-quality sunwear with 100% UV blocking lenses, and to throw on a sun hat for an added layer of protection.

UV protection is important for individuals of all ages—especially children—who are more susceptible than adults to the sun’s harmful rays, and tend to spend more time outdoors. It is estimated that up to 80% of a person’s lifetime exposure to UV rays happens before the age of 18.

Why are Blue Eyes More Sensitive to Light?

Lighter colored eyes like blue, hazel and green have less of a pigment called ‘melanin’ than brown eyes do.

Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

If you have blue eyes, you may have experienced this first-hand. Bright light may be uncomfortable or you may want to reach for your shades as soon as you leave the house on a sunny day.

That’s why optometrists urge blue-eyed patients to be particularly vigilant about UV protection, so as to mitigate their chances of developing eye disease and other complications.

How We Can Help

Whether you have blue eyes or not, sunglasses are an important part of keeping your eyes healthy for a lifetime.

At Eyeworks, we’ll be happy to advise on the perfect high-quality and protective pair of sunglasses to suit your needs and personal style.

Q&A:

Frequently Asked Questions with Dr. Richard Chu, D.O.

Q 1: Should I wear sunglasses even when it’s not sunny outside?

  • A: Yes! You should wear your sunglasses whenever outdoors during the day, even on an overcast, winter day. UV light can pass through clouds and reflect off surfaces like car windows and pavement.

Q 2: What type of sunglasses are the most suitable for blue eyes?

  • A: The most protective sunglasses are wraparound sunglasses that protect the eyes from every angle. You can also opt for photochromic lenses, which offer total UV protection but only become tinted when exposed to outdoor sunlight, and turn clear when you come indoors again. Your optometrist can help you choose the best lens and frame options for your needs and lifestyle.

COVID-19: Protect Your Eyes From Too Much Screen Time

You and your children are likely spending more time on mobile devices and computer screens than ever before. Too much time spent staring at screens can cause computer vision syndrome, or digital eye strain, in certain people. While not serious, this condition can be very uncomfortable, potentially causing:

  • Headaches
  • Eyestrain
  • Blurred vision
  • Dry eyes
  • Insomnia
  • Tiredness

Below are some useful tips to help you and your children avoid computer vision syndrome:

Blink more!

Staring at a screen strains the eyes more than reading printed material because people tend to blink 30-50% less. This can also cause your eyes to dry out. Be mindful of blinking and make it a habit when focusing on a screen, as it will keep your eyes healthy and lubricated.

Follow the 20-20-20 Rule

Give your eyes a break every 20 minutes by looking at an object located 20 feet away for 20 seconds. Doing so will allow your eyes to relax and will give both you and your eyes some rest.

Keep your distance

Your eyes work harder to see close up than at a distance. Try keeping your monitor or screen at arm’s length, or about 25 inches away.

Lighting matters

Make sure that your surrounding light is similar in strength to the light emanating from your screen. Contrasting levels of light, such as looking at a bright screen in a dark room, can strain the eyes.

Take breaks from the screen

You may want to stipulate ‘screen free’ time for yourself and/or your children, such as during meal times or for several hours throughout the day. Engage in hobbies that don’t require a screen, such as drawing, reading books, doing puzzles, playing an instrument or cooking (among many others).

Don’t use devices before bed

Studies show that blue light may affect your body’s circadian rhythm, also known as the natural wake and sleep cycle. Stop using screens one to two hours before bedtime or use nighttime settings to minimize blue light exposure.

Although it may require a bit of planning to protect your family’s eyes during this stressful time, ultimately, it’s all about balance — and what works for you and your family may differ from others.

From all of us at Eyeworks at Ft. Worth, we wish you good health and please stay safe.

Is School Work Causing Computer Vision Syndrome in Your Child?

Eye health tips for students from our Ft. Worth eye doctor

The start of fall means back-to-school for kids of all ages – and our team at Eyeworks wishes everyone a smooth and successful return to the classroom!

When your child enters school after a summer of outdoor fun, many of the summer’s vision hazards are left behind. Yet, that doesn’t mean all eye health risks are eliminated! Nowadays, the majority of learning is computer based – exposing students’ eyes to the pain and dangers of blue light and computer vision syndrome. Fortunately, a variety of helpful devices and smartphone apps are available to block blue light and keep your child’s vision safe and comfortable.

To help you safeguard your child’s vision for the upcoming semesters and the long term of life, our Ft. Worth optometrist explains all about computer vision syndrome and how to prevent it.

Symptoms of computer vision syndrome

It’s smart to familiarize yourself with the signs of computer vision syndrome. If your child complains about any of these common symptoms, you can help prevent any lasting vision damage by booking an eye exam with our Ft. Worth eye doctor near you:

  • Eye irritation and redness
  • Neck, shoulder and back pain
  • Blurry vision
  • Dry eyes, due to reduced blinking
  • Headaches

Basics of blue light

Students spend endless hours in front of digital screens, be it a computer monitor, tablet, or smartphone. There is homework to be done, research to be conducted, texting with friends, and movies and gaming during downtime. All of this screen time exposes your child’s eyes to blue light.

Many research studies have demonstrated that flickering blue light – the shortest, highest-energy wavelength of visible light – can lead to tired eyes, headaches, and blurry vision. Additionally, blue light can disrupt the sleep/wake cycle, causing sleep deprivation and all the physical and mental health problems associated with it. As for your child’s future eye health, blue light may also be linked to the later development of macular degeneration and retinal damage.

How to avoid computer vision syndrome

Our Ft. Worth eye doctor shares the following ways to block blue light and protect against computer vision syndrome:

  • Computer glasses, eyeglasses lenses treated with a blue-light blocking coating, and contact lenses with built-in blue light protection are all effective ways to optimize visual comfort when working in front of a screen. These optics reduce eye strain and prevent hazardous blue-light radiation from entering the eyes.
  • Practice the 20-20-20 rule; pause every 20 minutes to gaze at an object that’s 20 feet away for 20 seconds. This simple behavior gives eyes a chance to rest from the intensity of the computer or smartphone screen, preventing eye fatigue.
  • Prescription glasses can be helpful when using a computer for long periods – even for students who don’t generally need prescription eyewear. A weak prescription can take the stress off of your child’s eyes, decreasing fatigue and increasing their ability to concentrate. Our Ft. Worth optometrist will perform a personalized eye exam to determine the most suitable prescription.
  • Moisturize vision with eye drops. One of the most common symptoms of computer vision syndrome is dry eyes, namely because people forget to blink frequently enough. Equip your child with a bottle of preservative-free artificial tears eye drops (available over the counter) and remind them to blink!
  • Blue light filters can be installed on a computer, smartphone, and all digital screens to minimize exposure to blue. A range of helpful free apps are also available for download.
  • Limit screen time for your child each day, or encourage breaks at least once an hour. Typically, the degree of discomfort from computer vision syndrome is in direct proportion with the amount of time your child spends viewing digital screens.
  • Set the proper screen distance. Younger children (elementary school) should view their computer at a half-arm’s length away from their eyes, just below eye level. Kids in middle school and high school should sit about 20 – 28 inches from the screen, with the top of the screen at eye level.

For additional info, book a consultation and eye exam at Eyeworks

When you and your child meet with our Ft. Worth eye doctor, we’ll ask questions about your child’s school and study habits to provide customized recommendations on the most effective ways to stay safe from computer vision syndrome and blue light. Our optometrist stays up-to-date with the latest optic technologies and methods to prevent painful vision and eye health damage from using a computer, so you can depend on us for contemporary, progressive treatment.

At Eyeworks, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision. Call us today: 817-346-7077 or book an appointment online to see one of our Ft. Worth eye doctors.

Your Child’s Eye Exam & Their Future

Preparing for school means new school supplies, meeting new friends and teachers, and ensuring your child visits their eye doctor for aneye exam. Although schools may offer vision screenings within a few weeks or days of the new school year to ensure a child doesn’t struggle with poor visual acuity, none of the staff or even trained nurses check for visual problems, such as binocular vision and accommodative eye skills that play a significant role in near vision. Children who develop reading problems may have passed vision screenings yet were never examined by a professional optometrist.

Another benefit of coming to our practice is that we specialize in myopia management. Traditionally, the only way to handle nearsightedness or myopia progression in a child is to increase the prescription, often resulting in thicker glasses. Over a few years, a child will end up jumping from a low prescription of -.5 or -1 to a high prescription of -3 or worse! Unfortunately, high myopia has been identified as a lead cause for eye disease in old age, such as macular degeneration, cataracts, glaucoma, and even retinal detachment. A person can be 3-4x at risk for eye disease from having a prescription of -4 compared to someone with a low prescription.

Why does myopia cause eye disease?

Although LASIK surgery can help you see without eyeglasses, once a person’s eyes have worsened to a low prescription, the shape of their eye has elongated to a point that leaves the retina in a precarious state. Laser vision correction merely corrects the surface of the eye, but without preventing myopia progression, the damage has already been done. Therefore, the only way to safely secure one’s vision from greater risk is myopia management, in other words, taking steps to stop progression in its tracks.

What should a parent consider for their child’s next year at school?

Come to our practice and schedule an eye exam with our eye doctor, Dr. Robert Chu. We’ll not only evaluate the child’s complete eye health, but we’ll guide on the proper steps to slow myopia progression. We have methods through specialty contact lenses to stop advancing myopia, but often we’ll educate parents on how to slow progression through good habit building.

  • Children need 2 hours of outside play. Build their long-vision muscles!
  • Reduce screen time
  • Practice the 20-20-20 Rule.
    • Take a break from close vision work every 20 minutes,
    • Then look at something 20 feet away (or further)
    • Spend at least 20 seconds doing this before returning to your close-up work.

We look forward to seeing you and your children and getting the entire family prepared for the new school year with confidence & healthy vision.

School and Vision: 2 Important Partners

It’s February and that means we’re smack in the middle of winter, which is also the middle of the school year. It’s the season when kids fervently hope for snow days and parents hope they don’t happen. As we head towards the second half of the school year, you’ve probably attended a few parent-teacher conferences and discussed your child’s education.

Like peanut butter and jelly, school and vision go hand-in-hand. Both are important partners in ensuring that children excel in their learning, extracurricular activities, and relationships with their peers.

ADD/ADHD and Vision Problems

Did you know that certain vision problems can mask themselves as behavioral or learning difficulties? In fact, education experts often say that 80% of learning is visual.

A 3rd grader may be misdiagnosed with ADD or ADHD if they display behaviors like being fidgety, having difficulty focusing or concentrating, or having a short attention span. These symptoms may not always be purely behavioral; they could be vision-related. A child who experiences blurry vision, suffers from headaches oreyestrain, or itches their eyes excessively may, in fact, have a refractive error such as myopia (nearsightedness), hyperopia (farsightedness) or astigmatism, or another condition such as convergence insufficiency.

Undiagnosed myopia, for example can cause these same types of behaviors that are commonly attributed to attention disorders. That’s because if your child has to squint his eyes to see the board clearly, eyestrain and headaches are bound to follow. Struggling with reading or writing is common too. Other vision disorders can cause similar behavior patterns. An additional challenge is that kids don’t always express their symptoms verbally, and often they don’t even realize that other people see differently than do.

This can also impact kids emotionally. When they feel like they’re not keeping up with their peers or their learning is inferior in some way, this may lead the child to act out verbally or even physically.

Distinguishing between colors is an important skill for early childhood development. While color vision deficiency affects both children and adults, kids, in particular, can experience difficulty in school with this condition. Simply reading a chalkboard can be an intense struggle when white or yellow chalk is used. When a teacher uses colored markers on a whiteboard to draw a pie chart, graph, or play a game, this can be a difficult experience for a young student with color blindness. A child, his or her parents, and teachers may even be unaware that the child is color blind.

What School Vision Screenings Miss

Many parents believe that an in-school vision screening is good enough. However, an eye chart test only checks for basic visual acuity, so kids with blurry or double vision, for example, may be able to pass a vision screening while still struggling to read, write, or focus on the board. Children who have problems with their binocular vision, which means using both eyes together to focus on something, can pass the screening when they use just one eye to read the chart.

Studies show that a whopping 43% of children who have vision problems can successfully pass a school vision screening. This means that the vision test may fail to detect the more subtle but significant and treatable vision problems. Early detection and diagnosis is critical to maintaining healthy eyes. That’s why it’s so important to make eye care a part of your child’s healthcare routine.

The Importance of Yearly Eye Exams

The #1 way to do this is to schedule annual eye exams. Your eye doctor can perform a comprehensive pediatric eye exam to check visual acuity, visual clarity, binocular vision, and screen for any eye diseases or vision problems.

Because children develop so rapidly at different ages, it’s essential that eye exams are done at specific stages of their young lives. In fact, The American Optometric Association (AOA) recommends regular eye exams at age 6 months, 3 years, before school starts, and every 2 years thereafter.

Simply being aware of the tendency to associate a child’s learning issues with a learning disability or attention disorder instead of an underlying vision problem is critical for parents and educators. Both are partners in a child’s education and they must work together to ensure that each child gets the health care and attention he or she needs.

If you notice changes in your child’s schoolwork, behavior with friends or in sports or other after-school activities, it may be time to schedule an eye exam. You’ll want to be sure that your kids have all the tools they need to succeed in school and beyond.

What You Need to Know About Glaucoma – The Sneak Thief of Sight

January is National Glaucoma Awareness Month.

What is Glaucoma?

Glaucoma, a silent eye disease, is the most common form of irreversible blindness in the world. It is actually a group of diseases that causes progressive damage to the optic nerve.

  • Glaucoma is a progressive eye disease that can lead to permanent vision loss if not controlled.
  • There is currently no cure for glaucoma, but there are many treatments available for stopping and slowing the progressive damage to the eye. Treatment, however, can’t reverse damage that is already done.
  • Glaucoma affects the optic nerve which sends visual information from your eye to your brain.
  • Glaucoma is called the “Thief Sneak of Sight” because there are often no symptoms in the early stages such as pain or “pressure sensation” as one may expect, and by the time it is diagnosed there may already be permanent vision loss.
  • When vision loss occurs, peripheral vision is typically affected before central vision. As a result, glaucoma is a major public health issue because individuals usually do not notice any problem with vision until end stages of the disease when there is severe and irreversible vision loss.
  • Awareness and regular eye exams are key to early detection and preventing vision loss.

What Causes Glaucoma?

Glaucoma is caused by a buildup of natural fluid that doesn’t drain properly from the eye. The buildup of fluid can result in high pressure in the eye which is the most common cause of the condition. There are many types of glaucoma, which include:

Chronic (open angle) glaucoma occurs when pressure builds up over time, usually as a result of aging. This is the most common type of glaucoma.

Acute (angle closure) glaucoma is an acute condition where pressure builds up suddenly and demands immediate medical attention. Symptoms include blurred vision, eye pain, headaches, seeing halos around lights, nausea and vomiting.

Secondary glaucoma results from another eye disease, condition or a trauma to the eye.

Normal tension glaucoma is when there is no build up of pressure but the optic nerve is still damaged. We are still not yet sure what causes this type of glaucoma.

Who is at Risk for Glaucoma?

Everyone is at risk of glaucoma however there are certain factors which increase the likelihood of developing the condition. Vision loss from glaucoma can be greatly reduced when detected and treated early which is why knowing your risk factors can play a tremendous role in prevention.

Age

Age is one of the biggest risk factors, as your chances of developing glaucoma increase significantly after the age of 40. In fact people over 60 years old are six times more likely to get the condition.

Ancestry and Family History

Individuals from African American, Hispanic, Asian and Native American or Aboriginal Canadian descent are at increased risk. Family history is a very strong factor as the condition occurs twice as much in people with close relatives who have had glaucoma.

Previous Eye Injury, Traumas or Surgery

Eye injuries, traumas or surgeries have been known to sometimes cause secondary glaucoma which can happen immediately after the injury or procedure, or even years later. Even childhood injuries can result in secondary glaucoma later in life.

Use of Steroids

Studies show that prolonged steroid use is linked to increased elevated intraocular pressure which increases the risk of open-angle glaucoma.

Certain medical and eye conditions such as diabetes, hypertension and high myopia (nearsightedness) also increase a person’s risk of developing glaucoma.

Glaucoma Treatment

While there is no cure for glaucoma, there are treatments to slow down the progression of the disease including eye drop medications, iridotomies, iridectomies, laser procedures and surgeries.

Glaucoma Prevention

Other than taking care of any underlying conditions that may increase the risk of developing glaucoma, there is little one can do in the way of prevention. You can however reduce your chances of suffering vision loss. The first step is knowing the risk factors and signs of the condition (even though as mentioned most cases have no symptoms in the early stages, until vision is already lost).

The best possible way to prevent vision loss is to have regular comprehensive eye exams to check the health of your eyes and if your eye doctors prescribes medication for glaucoma, make sure to diligently take them as directed. Your eye doctor will be able to conduct certain tests to detect eye diseases such as glaucoma before you even begin to notice symptoms. If you have any of the risk factors above, mention it to your eye doctor, and always be sure to schedule a yearly eye exam, or as often as your eye doctor recommends, to check the health of your eyes and rule out any underlying or developing eye conditions like glaucoma.
