Does Eye Color Affect Vision?

Posted on 09/13/2018

Eye color ranges dramatically across the human spectrum, with some people having irises so dark they appear almost black, while others have a pale shade of blue or green. But is there any functional difference between blue, brown, and green-eyed people? Or is the difference only cosmetic? At the Brass Eye Center, we strive to be a comprehensive resource for eye care in the Latham & Clifton Park, NY communities. If you're wondering how eye color affects vision, we'd love to throw some light on the issue.

How Eye Color Affects Vision

According to some studies, there is a slight difference in vision capabilities between people with light and dark colored eyes. Lighter eyes, such as blue or green eyes, have less pigment in the iris, which leaves the iris more translucent and lets more light into the eye. This means that light-eyed people tend to have slightly better night vision than dark-eyed people. However, darker eyes act like a stronger filter for light, which means that dark-eyed people tend to see better in bright sunlight and are less susceptible to glare.

These differences may even go beyond vision abilities. Because lighter irises let in more sunlight, they also let in more dangerous UVA and UVB rays, which can damage the retina and other components of the eye. This may put light-eyed people at an increased risk of developing eye conditions like macular degeneration.

While there is evidence to support these differences, more research is needed to fully understand the differences between light and dark-colored eyes. One thing is for sure, though: no matter what color your eyes, it's critical to maintain regular eye checkups as you age to check for vision problems and treat them before it's too late.
