Picture yourself riding your bike on a beautiful sunny day in the Tri-Cities along the Sacagawea trail with your fiance. You're having a lot of fun and you're competitive, so you're moving fast. Suddenly, without warning, your boyfriend stops in front of you and you run into his back tire. You fly over the handle, clear him and his bike, and land on your side and head, bouncing to an ungentle stop. Sound a bit extreme? Well, this is exactly what happened to one of our employees last year... and she MARRIED the guy!
She not only suffered from a significant concussion (shameless plug for Dr. Hedman's blog this month), but she also was wearing her sunglasses at the time. Everyone knows they need sunglasses with 100% UV protection, but most people don't even think about whether their lenses are shatter resistant.
Although all non-laminated lenses must pass the ANSI standards (American National Standards Institute), which is to drop a 5/8 inch steel ball weighing approximately 0.56 ounce from a height on 50 inches upon the horizontal upper surface of the lens for dress wear, (industrial wear is even more strigent). The lens materials that are best for shatter resistance are polycarbonate lenses and trivex lenses. Polycarbonate lenses are not as optically clear of a meaterial and they're easy to scratch. WE highly recommend trivex lenses if clarity is important to you. However, if you need high velocity protection, that is typically made in polyccarbonate. Look for a marking on the lenses or the frame that has a variation starting with Z87, or if you need high velocity safety frame, look for Z87+. A quick demonstration of the difference between safety lenses and non safety lenses is available on a video.

If you're doing an activity where a safety frame is necessary, they're available in several frame manufacturers. We carry Wiley X in our Pasco location and some of our Oakley frames are also safety rated.
