Blinded by the cheerful prospects of a sunny day, people often overlook the harmful effects of UV rays on your eyes. Dr. Andrea J. Stein emphasizes the use of sunglasses to protect your eyes from harm, and even irreversible damage.

Polarized lenses are designed to reduce glare from reflective surfaces. The reflection of light causes it to magnify, multiplying the potential for eye damage. Polarized lenses are coated with a chemical that acts as a filter and protects your eyes from harmful UV rays, while also providing clearer vision.
At her optometry practice, Dr. Stein offers various sunglass options, including lenses that fit over your eyeglasses if you normally wear them, or prescription shades that darken in daylight.
There are other measures that can protect your eyes from UV rays further. A broad-brimmed hat, for example, functions as protection from direct sunlight. If you wear contact lenses, opt for lenses that offer UV protection. Wearing sunglasses in addition to contacts can provide optimum protection.
