Blue Light

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.

Q&A:

Frequently Asked Questions with Dr. George Fung, BSc (Hons.), OD

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.

5 Reasons to Buy Blue Light Glasses In-Store

Wearing blue light glasses has become more and more of a trend, and there’s a very good reason for it! Blue light contributes to eye strain and can disrupt sleep patterns. Although more research is needed, some studies have even suggested a link between blue light exposure and diabetes and heart disease

As a result, people are turning to an online retailer to order these glasses. While it’s logical that people would opt for the convenience of purchasing blue glasses online, it’s important to be wary of the hassle and inaccuracy that can result when you don’t order through an optician.

Check out these 5 reasons you should we wary of buying blue light glasses online:

1. Not getting what you asked for

According to a study recently conducted by The American Optometric Association (AOA) that had researched the 10 most popular online retailers, 29% of eyeglasses ordered online had at least one lens that didn’t meet the required prescription. Wearing the wrong prescription can cause eye strain and headaches. The advantage of buying these glasses at an optical practice is that you can be sure you’ll get the right fit and correct prescription for your needs, ensuring optimal comfort and clear vision.

2. You can’t verify the quality

The problem with ordering online is that you can’t assess the quality and check for a loose hinge. Browz Eyeware only stocks quality frames and our optometric staff is trained to ensure you wear the proper fit and enjoy quality eyewear.

3. Cheaper frames can cause skin irritation — or worse

Along the same line, low-quality frames can end up costing you more in the long run. When browsing online, certain frames may look more expensive but could be made of low-grade materials that can cause skin irritation over time. Not only can they irritate your skin, but they can also get bleached by UV rays and the finish can worsen after a few months of wear.

4. Online virtual try-on’s can’t ensure satisfaction

If you’re buying glasses online, you’ll often have access to some sort of virtual try-on feature. This requires you to upload a forward-facing, close-up photo of yourself and you can then superimpose images of different frames on your face to see how they look.

While a virtual try-on can give you a rough idea of how you’ll look wearing different frames, it can’t tell you how the frames will feel.

5. Know what’s being cut to offer lower prices

Online retailers cut costs by using cheap materials and cut corners on customer service and safety standards. Over 20% do not meet ANSI safety standards and you don’t get the personalized attention and fitting expertise of a qualified optician. That’s a huge part of the value equation!

Eliminate the guesswork that comes with ordering online and get your blue light glasses at Browz Eyeware in Calgary. We’ll ensure that you get the perfect fit, quality and comfort thanks to our highly trained optometric team.

Protecting Your Eyes From The Desk Job

Spending many hours staring at screens can cause computer vision syndrome, or digital eye strain. While not serious, this condition can be very uncomfortable.

Symptoms of computer eye strain include:

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

If your eyes feel any of the above symptoms, the way you utilize your computer might be to blame. Below are some useful tips to help you 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.

Rest your eyes

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.

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

You may want to stipulate ‘screen free’ time for yourself. Engage in hobbies that don’t require a screen, such as drawing, reading books, or cooking.

Modify your workstation

Position your computer screen so it’s 20 to 24 inches from your eyes. The center of your screen should be about 10 to 15 degrees below your eyes for comfortable positioning of your head and neck. This will reduce neck, back, and shoulder pain, and eye strain.

Don’t use devices before bed

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

Get Computer Glasses

Computer glasses have multi-layer coating design to reduce glare, reflect blue light away from the lens and relieve long-term eye strain caused by excessive computer use.

Having a yearly checkup can help you preserve your eye health. Contact Calgary to learn more about how to reduce eye strain when working on computers.

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 Browz Eyeware at Calgary, we wish you good health and please stay safe.
