Interpretação de Texto - UNIRIO

Research shows that sunscreens may not be as effective as hoped at preventing sunburn. Users may be spending long hours in the sun with a false sense of security, and though lotions may protect against sunburning UVB rays, it does little to block out the potentially more dangerous UVA rays. Another worry is the long-term effects of the chemicals contained in the suntan lotion themselves. To make spending time outdoors safer, a company called Frogskin, Inc., located in Scottsdale, Arizona, is marketing a line of clothing called Frogware that, wet or dry, protects the user from the damaging effects of the sun more effectively than sunscreens.

"Our T-shirts give you the same amount of protection from the sun that a heavy sweat shirt would", says Jan Steinberg, president of Frogskin. "But who wants to wear a sweat shirt in the water?" A typical cotton T-shirt, for instance, has a sun protection factor (SPF) of 5; a Frogskin T-shirt has a SPF of 30. Frogwear, says the maker, blocks out 98.5% of all UVB rays and 97% of all UVA rays. The fabric, which is lighter than cotton but more durable, also helps keep you cool, by wicking perspiration away from the skin. In addition, Frogwear absorbs very little water when wet and dries quickly. Prices range from $ 18 for a hat to $ 50 for a sports jacket.
