Sunglasses, a somewhat recent fashion statement.
In the 1950′s sunglasses became a popular style statement. Stars started wearing them, and not just outdoors, but indoors and in the evening too. (Crazy, right?)
You weren’t cool unless you had tones on. However using sunglasses is more than about being cool or stylish. Sunglasses have a real use, to shield the eyes against unsafe UV rays from the sun. That’s precisely why I bought some killer shades recently.
Too much exposure to ultra violet, or UV rays can trigger both brief and long term ocular problems. Such troubles consist of photokeratitis, snow loss of sight, cataracts and various eye cancers. A few people I know have had cancer, so I wanted to avoid all of the risk I could.
Medical professionals warn the public often about using UV obstructing sunglasses. They also caution that throughout solar eclipses, the defense of sunglasses is inadequate. Just don’t be stupid by staring directly at the sun and you should be fine. But just since sunglasses are higher priced does not necessarily make them much better at protecting against UV rays.
Expensive brand names do not assure optimal UV protection, so price is not an indication of quality. One research experiment found that a pair of sunglasses costing seven dollars a pair had much better security against UV rays than one of the name-brand designers.
Sunglasses for kids are also extremely crucial. Children’s ocular lenses are thought to send more HEV light than adults. If the eyes with age, this can cause yellowing. HEV has actually been implicated as the reason for age-related macular degeneration.
Sadly, there is no set requirement for sunglass producing besides safety screening. So not all sunglasses have some kind of UV security so it is vital to do your research before purchasing!
