A little more detail about my earlier post on Sunglasses and eye protection.
The classic rock band ZZ Top told us to buy cheap sunglasses, but is this good advice? Perhaps not. Cheap glasses are often made of brittle acrylic plastic, which can shatter and cause eye damage. And they scratch easily. Better glasses are made with polycarbonate or CR 39, which are more resistant to shatter, and are also light weight. Make sure the lenses are 100% UV rated to provide maximum protection.
Also, frames should wrap around the sides, to protect from glare. This is particularly important where there is lots of reflected light — in snow, or on a lake.
It is not necessary to spend a lot of money to get the protection you need from your sunglasses. But don’t just buy them because they’re cheap, or they look cool. Read the labels and do your homework. Also, avoid the glasses that have lots of jewels all over them. They just look silly.
