Not only did women with light-colored eyes experience less physical pain, but they also reportedly had less anxiety, depression, and negative thoughts.
In addition, some studies have linked specific eye colors to diseases like diabetes, melanoma, and vitiligo.
A 2012 study out of the University of Colorado School of Medicine found that people with blue eyes are less likely to have vitiligo, a skin condition that results in the loss of brown pigment from certain areas of the skin and leaves white blotches across some parts of the body.
This may sound like a stretch, and more research will be needed to solidify the claim, but researchers believe it may have something to do with our evolutionary roots — thousands of years ago, our Northern European ancestors found light-colored eyes more attractive and ideal for mating.
Thus, it's possible that blue-eyed people ended up having more of a competitive edge, at least in Northern Europe.
