How does sunscreen protect against uv rays?
UNTIL RECENTLY, sunsreen protected you from UBV rays. Now, they are finally selling sunscreen that protects you from BOTH UVB AND UVA, which is also dangerous. In a related story of marketing manipulation, when you buy sunglass's BEWARE. The sticker on it will say 100% UV PROTECTION. What they don't say is that protection is from UVB ONLY! UVA rays are very damaging. According to my vision Dr. who is brilliant, wearing sunglass's with only UVB protection is WORSE than wearing no sunglasses! Here's why: with NO sunglasses, your pupil will close MORE and let less harmful rays into your eyes. When you wear UVB sunglasses, the pupil is shaded, and tricks your pupil to open wider. THEN, MORE dangerous UVA rays can enter you eyes and causeWORSE damage!!!!! Whenever you buy sunglasses, spend the extra money and buy ONLYthe ones that say "Protects against UVA & UVB rays."
