Even when I was a little girl, random people would come up to me and compliment me on my eyes. My bright green eyes have constantly caused people to stop a conversation to tell me how beautiful my eyes are. I am not going to lie, I love being complimented on the color of my eyes, but little do people know I have absolutely horrible vision. I never realized how bad my vision was until the 5th grade when my eye doctor told my mother I desperately needed glasses. The older I got the worse my eyesight got; each doctors appointment my contact prescription would go higher and higher. So, could there be any possible causation between light eyes and bad eyesight? If so, this would mean the Null Hypothesis would be there is no connection between light eyes and bad eyesight, while the Alternative Hypothesis would be there is a connection between light eyes and bad eyesight.

When looking to discover which of my hypothesis was correct, I came across a lot of interesting studies and news articles. This study, was conducted to see if darker eyes have better reaction times than lighter eyes. The study observed 59 male rugby athletes regarding a peripheral vision test and a goal-kicking test in order to determine if the darker eyed rugby players had a faster reaction time than the lighter eyed rugby players. At the end of the study it was concluded that the dark eyed rugby had no significant difference than the light eyed rugby players. Although this study supported my Null Hypothesis, there could have been a number of confounding variables and it is unclear the number of light eyed rugby players that are being tested versus the number of dark eyed rugby players that are being tested. According to an article by Everyday Health, lighter eyes tend to be more sensitive to lights. People with lighter eyes have less pigment in their eye than a person with dark eyes. So by having less pigment in your eyes cause you to have worse vision? According to UCSB Science Line, the answer is no – pigment does not effect your vision. But just because pigment does not effect your eyesight, could it be effecting something else? According to Everyday Health, there is a greater chance that people with lighter eyes have a better chance of developing cancer. Why is this? Since people with lighter eyes have less pigment, they have less protection of Ultraviolet Rays, which can increase one’s chances of melanoma of the uvea in the eye. According to the Ocular Melanoma Foundation, Ocular Melanoma has about 2,000 to 2,500 cases in the United State each year. So even though you may have lighter eyes and have a higher chance of developing Ocular Melanoma, it is a very rare cancer that one with lighter eyes should not worry too much about. The easiest way to prevent Ocular Melanoma is not to stare at the sun and to wear sunglasses on bright, sunny days.
All in all, the color of your eyes do not have any effect on your vision. For me, I guess I was lucky to have pretty eyes but just unlucky to have bad vision. Therefor, the Null Hypothesis would stand and eye color has no causation to eye vision. Even though eye color does not effect your vision, light eye color can increase your chances of developing Ocular Melanoma. So although my vision may not be affected by my eye color, my eye color may cause me to have a slim chance to develop Ocular Melanoma!
