Eye color is determined by the amount and distribution of melanin in the iris. Gray eyes are a result of a low amount of melanin in the iris, causing light to scatter and reflect off the collagen fibers in the stroma of the iris. This scattering of light creates the appearance of gray eyes. It is a less common eye color, but can be influenced by genetics and can also change with age or due to certain medical conditions. **
