Indeed :) They're pretty tough though, they can take a 12 ft/lb 0.22 or 0.177 airgun pellet without shattering, and apparently birdshot from a 12 gauge won't even penetrate it.

They look like the glasses used for clay bird shooting, if it can handle bird shot they probably are similar.

The worst thing they have to handle in the lab is the occasional splash of nasty chemicals, but I believe in thorough testing of the items I trust my safety with :)
