Do you think eye color affects vision?
- I'm not sure. (29%)
- No, that's silly. (35%)
- Yes, of course. (35%)
In April, we published the poll, “Do you think eye color affects vision?” And it appears EnVision readers think it’s a bit silly that eye color would affect your vision. The truth? It kind of does!
Matter of Fact
Eye color doesn’t significantly affect the sharpness of your vision, but it can affect visual comfort in certain situations. It all comes down to the density of the pigment melanin within your iris, which determines what colors of light are absorbed or reflected. Simply put: The higher the concentration of melanin pigment in the iris, the darker the eye color. And a higher concentration of pigmented cells within the iris acts as an internal sun-shade, dissipating more sunlight and radiation.
Brown Eyes vs. Baby Blues
Those with darker colored eyes experience less visual discomfort in bright, sunny conditions. Also, darker irises reflect less light within the eye, reducing susceptibility to glare and improving contrast discernment—so people with darker eyes may have better vision in high-glare situations, such as driving at night.
On the flipside, by having a low concentration of melanin pigment, light-colored eyes lack the additional protection. More harmful UV light can pass through lighter colored irises, increasing your risk for developing cataracts and macular degeneration. Wearing sunglasses with UV-blocking lenses can help reduce these risk factors!
Protect Your Eyes
So even though the color of your eyes should not affect how clearly you see, it may affect your eyes’ sensitivity to the sun. Regardless of your eye color, whether they are dark or light, it’s important to get in the habit of protecting them with sunglasses. Find an eye doctor near you to help determine the best type of sunglasses to fit your needs and lifestyle, or shop Eyeconic for the perfect pair—so you never have to worry about getting caught in the sun unprotected.
