anti reflection coating

As the weather began to change, I tend to start thinking about the sun. For my family, which means that the cap, sun screen, UV protection of my children and sunglasses. I think it is safe to say, now most people know that the destructive effects of ultraviolet radiation is. I'm not so sure, everyone including protective glasses in the sunny list. In fact, today I look at our office windows, there are very few people go appropriate sun glasses.
Children are most at risk. When, in fact, I would suggest everyone, but especially for small children, I would strongly recommend that, anyone under 20 years of age to wear dark sunglasses and a hat. After the 20 lens hardens, the protection we have some built-in the harmful ultraviolet rays. This enhancement is gradual, so the child is small, more important is to protect his eyes. Long-term effects, this protection may contribute to the prevention of cataract. Some other conditions, can be minimized with proper sun protection include: pterygium, macular degeneration, keratitis, pingueula, tumor of eyelid. These conditions can be at any age.
I should look for what, to ensure that I get the best protection? Buy reputable sources. Ask, if you have 100% UVA and UVB. Consider getting a polarized lenses, if you drive a lot, or spending time in the water or snow. Lens polarization piece of dazzling (from the car, snow or water) is a process.
A good pair of sunglasses, you should see what? Full coverage, a pair of good will be limited to not just in front of the light from different angles. 100% UV Sunglasses, still harmful radiation transfer to your eyes more and more not much point. You may want to consider to spend extra money, polarized lenses are. For those with a higher light sensitivity, it may be an anti-reflective coating or surface coating inside the lens is high quality, to reduce the internal reflection. I most like sunglasses Maui Jim is that they provide amazing coverage, protection, anti reflection coating, optical polarization and let me to spend time on or near the water (I live on the west coast of the most loved function) and I didn't have any disturbance of vision.
