Sun glasses

Tweet

Friends when summer rolls around, we try to avoid too much sun exposure. We use sun glasses, hats, umbrellas. I use sunglasses of a reputed brand. The sun glasses sold here in my city may cost anything from 50 rupees to 6000 rupees or more. They are not tested by government. We trust sunglass makers to label their products accurately. But they may not be doing their job. And that means you could face serious eye trouble in just a few years. Here are few simple tips to help you take care of your precious sight. Most of the glasses are marked with the “CE” logo. The logo indicates these glasses meet standard for blocking UV light. But if not, , you could be exposing your eyes’ delicate tissues to far more UV light than is safe. And that could result in permanent damage. So, please follow these simple guidelines to be sure your sunglasses are doing their job. Just stay away from cheap sunglasses. They’re more likely to fail UV protection requirements. It is advisable to get your sunglasses from your eye doctor or optician. In some comparisons, these were the least likely to be faulty. Wear wrap-around sunglasses. UV light can “leak” in from the side. Blocking this “leakage” is especially important if you spend a lot of time outdoors. Look for glasses that provide 99% - 100% of both UVA and UVB light. Some studies suggest that blocking blue light is also important. If you have any problems with color vision, be careful about the tint of your lenses – especially when driving. Reddish, yellow and green-tinted lenses can make it more difficult for you to see traffic lights. Be sure you’re getting plenty of antioxidants – especially vitamins C and E, and zinc. These antioxidants support eye health by mopping up the free radicals UV exposure causes. Finally, when you’re shopping for sunglasses, here are three things you don’t need: Darker lenses. Because eve clear lenses can be treated to block UV light, and glasses that are too dark can interfere with driving. Polarized lenses. No doubt polarization cuts glare, which can help with clarity. But polarization doesn’t block UV light. UV coating. This add-on about ultra violet radiations is often advertised for “extra protection” is pointless. If your sunglasses already meet the “UV400” standard, coating will only add cost. Hope my suggestions you find useful, do you use sunglasses? Do you take in to consideration, the points I said here. Please comment on this too. Professor
