Valerie - I don't know anyting about them. You'd think with a name like boroscopes (as opposed to something like "sodalimescopes") they should be safe. However, according to Mike's post above, they aren't. You should check out his site
www.auralens.com. In addition to a large selection of eye protection, there's a lot of information on the different types of protection and what they protect against (UV, IR and sodium flare.) I just got a pair of clip on AGW 203s.
