A Quick Guide To Sunglass Wear Why When And Where

A Quick Guide To Sunglass Wear Why When And Where



Sunglasses have been considered a​ fashion statement for decades, worn by celebrities and other famous folks in​ either a​ desperate attempt to​ conceal their identity or​ to​ play the movie star role, all while looking fabulous. Even though this usage still exists, more and more average people are realizing the importance of​ wearing them to​ protect their invaluable eyesight.

Even though the sun is​ over 93 million miles away, its harmful rays can be the sole cause of​ an​ assortment of​ health problems. Ultra violet radiation (also known as​ UV radiation or​ UV rays) is​ probably the largest solar-based contributor to​ such health problems. UV-A, UV-B and UV-C are the categories of​ UV radiation known to​ us at​ this time. With the exception of​ UV-C (which is​ believed to​ be absorbed by the ozone layer around the earth), these rays can have both short and long term effects to​ your eyes and your vision.

Now that you’re a​ bit more aware of​ why, you need to​ know more about when. For instance, UV rays reflect off of​ snow, sand, pavement and water, causing a​ greater risk for damage than in​ a​ “greener” environment, like a​ park or​ field. The rays in​ a​ reflective situation will be coming at​ you from two angles instead of​ the one in​ a​ greener environment, as​ the rays will bounce off of​ the reflective surface in​ addition to​ coming at​ you straight on. Wearing sunglasses that offer you UV protection will help to​ protect your eyes when in​ this type of​ circumstance.

High altitude is​ another situation for which sunglasses should be worn. UV rays are filtered out through the earth’s atmosphere, resulting in​ lesser amounts of​ the harmful rays converging with the earth’s surface. Simply put, high altitudes yield a​ greater amount of​ the rays because they haven’t had the chance to​ be filtered yet.

Between the hours of​ 10 am and 4 pm is​ the time of​ day when the UV rays are their most powerful, so protective eyewear is​ crucial during this timeframe, whether or​ not the sun is​ bright and beaming in​ the sky or​ hidden behind large amounts of​ clouds (both white and fluffy and dark and gloomy). UV rays can easily leak through the cloud cover and rain to​ wreak its irreversible damage on your eyes.

Since you now are aware of​ the situations that necessitate proper eyewear protection, you need a​ brief list of​ what to​ look for when shopping for your ideal pair of​ sunglasses. Typically, lenses that are green, brown or​ grey work the best, combined with a​ feature that filters out of​ at​ least 99% of​ UV-A and UV-B radiation and 75% - 90% of​ visible light. Taking care of​ your baby blues, browns and greens now will ensure you a​ lifetime of​ beautiful visions.
