Your eye color is unique to you. In fact, no two people have the exact same color of eyes. Because of this, eye color is one of the most distinguishing characteristics for people and is often a big part of identity. We’ve already written about the science behind how you get your eye color, but does that color also affect your vision?
Our expert doctors have shared how your eye color affects your vision:
The Science of Eye Color
In order to understand how eye color affects your vision, it will be helpful to understand how eye color develops. The iris is the colored part of the eye, and the amount of pigmentation within the iris determines your eye color. There are three genes that are responsible for determining the pigmentation. These genes are tied to your melanin levels.
Less melanin in the iris means lighter eye colors, like blue and green, and more melanin makes for darker eye colors, like hazel and brown. Check out our eye color science blog to learn more about determining eye color.
Light vs. Dark
Whether you have light or dark colored eyes, your eye color does actually have an impact on your vision.
If you have a lighter eye color, your eyes are more sensitive to light because you have less pigment and melanin in your irises to protect your eyes from the sun. This means that you could have a greater risk of macular degeneration, and that you might find yourself squinting more when you go outside during the day.
If you have a darker eye color, your eyes can often withstand high glare lights better than light colored eyes can. This is thanks to the greater amount of pigment and melanin in your iris. You could potentially be better at driving at night because your eyes allow for less light to reflect and cause glare. Despite your high light tolerance, though, you should still be wearing sunglasses to protect your eyes from UV rays.
There are a few studies that have looked at the impact of eye color on sports performance. The University of Louisville found that people with dark eye colors perform better at reactive tasks like hitting balls and playing defense, while people with light eye colors do better at self-paced tasks like hitting a golf ball, throwing a pitch, or bowling. However, there are not enough studies yet to fully support this theory. For now, it’s just a fun discussion to have with your teammates.
