... An optician and an opthoptic (sp)? We're off to see one tomorrow (thing #1 'failed her year three assessment (twice) because she didn't want to do the test). Thanks. (PS - she won't cooperate tomorrow either.)
Mini Boo wears glasses, at her final test, it was at the hospital where they shone a light into her eyes. I think by then, they'll know whether she genuinely can't see or is being stubborn.
As for what the difference between the two is, no idea, sorry.
