Unexpected driving danger


Prolonged exposure to the sun’s ultraviole­t A (UVA) rays has been shown to increase the risk of cataracts and skin cancer, and now researcher­s in JAMA Ophthalmol­ogy report that car windows don’t fully protect against the harmful rays. In their comparison of 29 different cars, investigat­ors found that the front windshield blocked about 96 percent of UVA rays, but the driver’s side window blocked as little as 44 percent. To reduce the risk, experts suggest wearing broadspect­rum sunscreen and wraparound sunglasses on daytime drives longer than 20 minutes.
