UV protection and Sunglasses
Summer is around the corner, and its time to enjoy the great outdoors and soak up the sun. When enjoying the great outdoors we must take a minute to think about UV protection for our eyes. UVA and UVB light have been proven to cause early development of certain eye diseases such as cataracts and macular degeneration. Newer studies have also shown that UV exposure may possibly accelerate presbyopia, which causes the need of reading glasses or bifocals.
Sunglasses are must when one is outside, not only in the summer but it is important all year round. Not all sunglasses are created equal, the most important factor is that it should block 99-100% of UV radiation. In Canada, it has been regulated that all sunglasses sold must provide full UVA/ UVB protection. This may not always be the case when buying eyewear online. It is always best to buy from a reputable place that you trust.
Sunglasses can come with polarized lenses. Polarized lenses offer exceptional optical clarity, because they block out reflective light rays. The vision through polarized lenses is like a high definition television.
Glasses can also have photochromic or transition lenses which become tinted when exposed to UV light. The benefit with these glasses is that your clear spectacles become tinted or polarized in the sun, so one doesn’t have carry two separate pair of glasses for indoors and outdoors. The only exception with photochromic lenses is that they do not change behind the windshield when driving. Your optometrist or optician can also provide you with prescription sunglasses so you can have great quality vision all the time
