I just phoned the optician where I last went for glasses and

Presumably most safety spectacles are paid for by businesses or
other workplaces and thus 'ordinary' opticians don't get to know
much about them.

My bifocals are safety specs to BS2097 (afar), plastic
lenses in a secure/shielded frame. Bought in an ordinary
opticians, and they were not expensive.
