While limited, there is some research showing that blue eyes may protect you against seasonal affective disorder. [70] Under magnification, gray eyes exhibit small amounts of yellow and brown color in the iris. Hazel eyes are due to a combination of Rayleigh scattering and a moderate amount of melanin in the iris' anterior border layer. Longer wavelengths of light tend to be absorbed by the dark underlying epithelium, while shorter wavelengths are reflected and undergo Rayleigh scattering in the turbid medium of the stroma. [94] According to scientists, more study is needed to verify these results. Amber eyes may also contain amounts of very light gold-ish gray. At first, you may not notice that you have a cataract.

This damage will cause your vision to become blurrier and more distorteda condition called macular degeneration. As of 2010, researchers believe that as many as 16 different genes influence eye color in humans, and most of these genes play a crucial role in the production, transportation, and storage of melanin pigment. This genetic switch limits how much melanin is produced in the iris effectively "diluting" brown eyes to a shade of blue. "Why Edinburgh residents are likely to be blue-eyed", "Genetic determinants of hair, eye and skin pigmentation in Europeans", "Eye Color Percentage for Across the Globe", "Is there any difference in the photobiological properties of melanins isolated from human blue and brown eyes? Genetic research suggests that until about 10,000 years ago, pretty much everyone had brown eyes. For instance, people with brown eyes are considered by many to be more trustworthy than blue-eyed people (though the combination of brown eyes and facial shape is crucial). Even though amber is similar to gold, some people have russet or copper colored amber eyes that are mistaken for hazel, though hazel tends to be duller and contains green with red/gold flecks, as mentioned above.
