I had a pair of safety glasses made by "Site For Sore Eyes" (yes, I will out them publicly) but I gave them a copy of my then-current prescription done by Kaiser Permanente Optical. This was about twenty years ago. The resulting glasses weren't even close! I could not see out of them at all! Since this was a freebee to the employees from my work, they (SFSE) would not re-do the lenses for free. Took the unusable glasses to Kaiser, they said the prescription was not mine at all. The new lenses made by Kaiser, at a cost of $200 USD, were effing perfect. Every two years you could get SFSE glasses by our contract. They never made them right unless you paid $75 USD for an exam, which was not covered by our union contract.I never knew how much i hated my government healthcare glasses until my company provided medical insurace. These are so much cuter and nicer.
