I had my optometrist make me a pair of bi-focal, yellow shooting glasses. Shatter-proof lenses and a wide lower part of the lens works great. I find that I rarely use the bottom for actual shooting, as the tops give me a good view of the front sight and the target.My complaint is wearing protective shooting goggles over my glasses. It's uncomfortable & a pain. Especially in the summer. sweat dripping on the lens, etc.
