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: 

#1: 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.

#2: 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. 

5 Reasons To Wear Sunglasses In The Fall

While it may not make much sense, you’ll get a better understanding by the time you finish reading this article. So let’s dive in and explore the 5 reasons you should protect your eyes from the sun in the fall.

Sunglasses: Summer Vs. Fall

The Sun’s Position

While we may squint more in the summer, the sunlight’s path to the eyes is more direct in the fall as the sun sits closer to the horizon. This places our eyes at greater risk of overexposure to UV rays.

Changing Temperatures

Irritating symptoms like dry, red, or watery eyes are often due to the season’s cool and harsh winds. The colder the air, the stiffer and thicker the eyes’ tear oils (meibum) become. Because thicker meibum doesn’t spread as evenly over the surface of the eyes, the tears can’t offer sufficient protection and moisture.

Minimize irritation by shielding the eyes from cool winds with wraparound sunglasses.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Killeen eye doctor has prepared the following answers to your questions about eye disease.

UV Rays

Exposing your eyes to the sun’s harmful ultraviolet (UV) rays is problematic year-round, as it can result in serious eye diseases, such as cataracts and macular degeneration. That’s why it’s important to wear 100% UV-blocking sunglasses anytime you’re outdoors, no matter the season.

Make sure to sport your sunnies even on cloudy days, as up to 90% of UV rays pass through clouds. Furthermore, outdoor objects like concrete and snow reflect a significant amount of UV rays into the eyes.

Fall’s Dangerous Sun Glare

Because the sun is positioned at a lower angle in the fall, it can produce a brutal glare that poses a danger for driving. Rays of light that reflect off of smooth surfaces like the metal of nearby cars can be so bright to the point of blinding the driver.

You can combat this dangerous glare by wearing polarized sunglasses. These lenses reduce the glare’s harmful effects by filtering out horizontal light waves, such as the ones reflected by a shiny car bumper.
