I don't wear sunglasses, but I wear glasses. Luckily, fashion has brought large lenses back in. I chose large lenses with plastic frames. Plastic is safer in case of a facial crash. I just made sure the lenses are both wide left-right and tall top-bottom. They keep the wind out of my eyes, and I'm very vulnerable to wind. My old small lenses seemed to direct wind into my eyes, compared with wearing nothing.
