Eye Color Sensitivity

Overview

The purpose of this study was to determine whether people with blue eyes were more sensitive to light than people with brown eyes. Scientists have found that blue eyes are lighter due to the lack of melanin and those with darker eyes such as brown are found to have higher levels of melanin. Melanin also acts as a sunscreen as well as a pigment for the eye. The less pigment makes it more sensitive. There are conditions that can affect one’s sensitivity such as having to wear glasses or having dry eyes or allergies. All of these factors are helpful for this experiment. The end results show that people with blue eyes are most sensitive to light out of the other eye colors (brown, hazel, and green). These findings support the hypothesis that the eye color blue would be most sensitive because there is less melanin. It acts as a sunscreen as well as a pigment for the eye. Blue eyes have the least amount of pigment which makes it most sensitive.
