Shedding Light onto Some Misconceptions about Sunglasses

 The correct sunglasses will protect the eyes from the damaging ultraviolet (UV) rays of the sun and prevent poor eyesight. However, some misconceptions should be corrected to get the maximum benefits from sunglasses.

 It's not true that darker sunglasses give more eye protection than the less-tinted ones. Some sunglasses with lighter shades may provide more protection than those with darker tints. The secret lies on the label that says 100 percent UV protection or UV400. However, not all outlets provide reliable information. Buy only from reliable companies to get accurate information. Lenses made of polycarbonate provide 100 percent protection while those made of CR-39 plastic lenses give 88 percent. Worse, triacetate lenses can provide only 40 percent.

 It's not true that kids don't need sunglasses. As a matter of fact, because children spend more time outdoors than adults and their eyes' pupils are larger as a percentage than adults' pupils, they are more exposed to the sun's UV rays.

 It's not true that people need to wear sunglasses only on sunny days. In fact, UV exposure can be greater on cloudy days. It is recommended that sunglasses be worn when spending more time outdoors, particularly at midday and in the summer.
