At an industrial site where I work they recently instituted a policy of wearing protective lenses. My employer gave us these cheap plastic safety glasses, but they scratch too easily, they fog up all the time, and they're generally uncomfortable.
However, prescription glasses (even those not rated for industrial protection) are permitted. Go figure. Someone suggested that for those who don't have prescription eyeglasses, then wearing a cheap set of drugstore reading glasses would suffice.
I still have marginally 20/20 vision--I don't need prescription lenses (yet, knock on wood!), but when I tried on the reading glasses with the least correction (+1.25 diopters, I believe), it still felt annoying. What I'd really like is a set of cheap glasses with neutral lenses.
My question is this: Does someone market/sell reading glasses with zero correction? If so, where can I get some?
