Around here sunglasses are a necessity. They do not call it “Sunny California” for nothing. The bright sun bounces off of the buildings and concrete in the big cities, and by the end of the day your eyes can hurt. Did you know that retinal sunburns are possible? Sounds odd but it is true. You can get sun damage inside your eyes like you can on your skin. I wear a good pair of designer sunglasses every day. Even the overcast days here have a lot of UV light bouncing around. I rarely see people who do not wear sunglasses anymore.
The reason I stick with good designer sunglasses is because of the quality of the optics. I want lenses that are guaranteed to filter out the spectrum of UV light that can be damaging to my retinas. Sight is a precious thing, and I will do what I need to do to preserve it. Let me give you an example of how you can cause damage over time and not realize it until it is too late to do anything about it. When I was younger, I was exposed to loud sounds such as rock concerts, blasting stereos and gunfire at shooting ranges without having hearing protection. Now I have high frequency hearing loss. I wear ear plugs now even if I am mowing the lawn. The damage was slow and subtle getting worse over time.
Now with sunglasses, I have always worn ones that were rated to block dangerous ultraviolet light. As far back as I can remember I have worn sunglasses. I have protected my eyes, and have no evidence of damage caused by environmental exposure to the sun. It would be nice if I could say the same thing about protecting my ears since I was young. I stick with designer sunglasses because they look good and the lenses are rated in the brand I buy to block the dangerous ultraviolet light.
