It's Science! | UV, the Scourge

Hey everybody!  The CATEYE Science Guy is back with more knowledge droppings, so buckle-up space cadets!  We're gonna go for a ride...

What causes true lasting damage to your eyes (besides these guys)?

It came from outer space...

ooooooo weeeee oooooo

Okay, but seriously, the American Academy of Ophthalmology and the American Optometric Association stress the need to protect your eyes by wearing a wide-brimmed hat, and sunglasses that block out 99-100% of both UV-A and UV-B light.  We don't have any hats, but boy do we got glasses!

Ultraviolet rays can damage the surface of the eye and the interior structures, such as the lens and retina.  This can open a door to all sorts of badness like cataracts and, some doctors suggest, Macular degeneration.

Bottom line is that you need to protect yourself from UV rays.  It's not important how dark the tint is, or if you have a sweet mirror coating like Sylvester Stallone.  You could have clear Polycarbonate lenses (which inherently block UV) and they would protect against UV just as well as some sweet mirrored Stallone shades (provided said sweet mirrored Stallone shades are treated to block UV).

 
And don't worry, all of the sunglasses at CATEYE Spectacles, though they may be old, have lenses that block 100% of UV-A and UV-B light.  This will help protect you from UV, the Scourge—basically, think of UV rays like the Shredder and the Foot Clan and our sunglasses like the Ninja Turtles.  C-A-T-E-Y-E power!  Kowabunga dudes.

Disclaimer: Obviously there are other things out there that can be harmful to your eyes and your vision—we're not telling you that if just wear 100% UV-A and UV-B blocking lenses that you can replace your Visine with acne cream.  Take care of yourselves people!
