People buy sunglasses for different reasons. Some do so hoping it will improve their appearance or make them look like a Hollywood movie star. Others wear dark glasses to conceal their identities while a few purchase them simply for fun. The majority of those who invest their money on a pair, however, are not only making a fashion statement. Their main concern nowadays is protection from the harmful rays of the sun.

In a cataract operation, the cloudy lens is removed, leaving the retina extremely vulnerable to UV radiation.

Photosensitivity is likely to occur in some people taking anticancer drugs, water pills, tranquilizers, antidepressants, antihistamines, birth control pills, Retin-A, anti-diabetic or high blood pressure medications, and topical antiseptic creams. "Probably the best known of these photosensitizing drugs is psoralen, used in so-called PUVA treatment of psoriasis. Studies have shown that PUVA can cause cataracts unless patients wear UV-absorbing sunglasses for at least 24 hours after treatment.
