I have brown eyes, with a hint of green in them, so they are borderline hazel. I wear glasses, as do all of my siblings (there are 5 of us) and both of my parents. Both my mom and dad have green eyes, and 3 out of my siblings have dark brown eyes, and one of my sisters has green eyes herself. Since we all wear glasses, I was curious- does eye color have anything at all to do with vision?
I’ve heard that people with blue eyes (and blue-eyed horses) have poorer vision than darker hued eyes since they absorb less light. Huh. This theory doesn’t stick with me since I have brown eyes and terrible vision, as do all of my siblings, none of which have blue eyes. Even my green-eyed sister has dark green eyes (like jade), so I really don’t think having lighter colored eyes make a difference. Am I wrong?
Studies have shown that darker eyes have better reaction times than lighter eyes do, and in a study done by the University of Louisville, the study revealed that people with darker colored eyes had better reaction time in activities, like hitting a baseball or boxing, than the lighter eyed counterparts. However, the same study showed that lighter colored eyes were able to do self-paced tasks better, such as throwing a baseball, bowling, or hitting a golf ball than people with darker eyes.
While it is true that people with lighter colored eyes are more sensitive to light since they have less pigment to their eyes to combat sunlight rays, and may have a greater chance of accruing macular degeneration, there is no clear proven evidence that eye color actually affects vision. No studies have been shown that eye color in any way can actually affect how a person sees.
