Here's one example: R-SG-24PL Description: XTS safety glasses, gray polarized polycarbonate lens, sapphire glossy blue frame, meets ANSI Z87+, ballistic Vo rated. Price Sheet/Order Form.
In fact, at $40, they the most expensive shooting safety glasses on the price sheet. The cheapest ones are $6. If you'd prefer more styles, though, check here.
My favorites, around $6 each. They comply with ANSI Z87+ and CE-EN-166.
