Blue Light

Why Are Blue Eyes More Sensitive To Light?

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.

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

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.

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

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 Europtical at Rocky River, we wish you good health and please stay safe.
