If you have blue or green eyes, you need to wear a pair of sunglasses every time you go out on a bright day. That’s because light-colored eyes are associated with a higher risk for sun damage and certain eye diseases, such as cataracts, macular degeneration, photokeratitis or “eye sunburn,” and certain cancers.
What’s With Your Eyes’ Color?
The amount of pigmentation or melanin levels within the iris determines the color of your eyes. When melanin develops, it creates a protective filter that reflects the light out of the eye. The more melanin present, the better eye protection you have. Lighter eye colors mean you have less melanin while darker ones mean you have more of it.
Light Sensitivity of Light-Colored Eyes
When light passes through the iris’ stroma, it does so more quickly when the color of the iris is blue or green eyes. The light then reflects off the layer of darker cells behind it and absorbs longer wavelengths of light. Shorter wavelengths of light like blue or green, however, tend to scatter as they pass back through the stroma. As more light passes through the iris, the nerves at the back of the eye get overstimulated. This results in light sensitivity or photophobia.
Protecting Your Eyes from UV Damage
Every eye care center recommends protecting your eyes from ultraviolet (UV) damage, regardless of your eyes’ color. Even when the sky is cloudy or overcast, it is a must that you wear sunglasses outdoors. Choose a pair with wraparound frames and lenses with 100% UV radiation protection. Wearing wide-brimmed hats or caps helps a lot, but if possible, make sure to limit your time outdoors.
