In-Reply-To:

I haven't bought laser eye protection in a while. -But check the usual safety glasses distributors (and the welders as well) they usually have the right filters.

One other item - in the industrial setting -- we did do a baseline eye exam (with retina pictures) for OSHA tracking - and now that these are part of most general eye exams - it is not too hard to do.

We also did general training and posted signage. And did periodic reviews to ensure that 1) the lasers did not hit "normal eye" level i.e. did not have reflectors/mirrors and focus points above a certain level, 2 - did not have beams headed to windows or doors to prevent scattering to passers-by and we did curtain off some areas to minimize scatter.

Hope that helps.
