Quote:Dollar Store will do fine. I developed advertising for a sunglass maker in the mid Nineties, and was briefed by an overly frank optics engineer. Basically, ANY glass, polycarbonate, Â or CR-39 acrylic lens with a light transmission in the 10-14% range gives you the same level of UV A and UV B protection. In fact, clear glass lenses aren't much worse-- that's why you can't get a suntan driving around with your car windows closed-- because glass blocks UV very effectively. So it all comes down to fashion. The Dollar Store sunglasses protect just as well. That said, I wear RayBan Wayfarers-- because they look good on me.
