Important Factors When Buying Sunglasses for Women. The right sunglasses stand out as an important defense against ultraviolet (UV) rays that can cause both short- and long-term eye damage, according to the American Academy of Ophthalmology in San Francisco, CA. The single-most important quality to look for when buying sunglasses to protect your eyes is a sticker or tag indicating that they block 100 percent of UV rays.
The more coverage from sunglasses, the less sun damage inflicted on the eyes. Women should consider buying oversized wraparound sunglasses, which help cut down on UV entering the eye from the side. At the same time, polarization reduces glare coming off reflective surfaces like water or pavements; it doesn’t offer more protection from the sun, but can help make activities like driving or water sports safer.
