Since sunglass wearers have the same potential exposure as everyone else to the impact of an airbag or an unexpected fall, all sunglasses should have polycarbonate lenses. Polycarbonate is the most shatter-resistant lens material currently available. To filter out bright light, especially in the blue hazard range, you should not get a blue lens, which transmits the potentially harmful blue light wavelengths. Neutral gray is a good choice because it does not change color values.
Lenses tending towards amber are effective at filtering out blue light.
People who wish to avoid glare, in sports such as fishing, can have the lenses custom-made with a polarizing filter. For most people, excellent polycarbonate sunglasses are available very inexpensively. If the person is not participating in a sport, then polycarbonate plano industrial eyewear is available in a number of tints. Several industrial quality sunglass models are well accepted by patients and cost less than one-tenth the price charged for sports sunglasses. It must be remembered that industrial eyewear and the majority of so-called sports sunglasses meet the requirements of ANSI Z87 a standard that specifically excludes sports use.
