In Boots they still use the frames where you slot the lenses into (which I prefer). Have tried many masks and the washing up liquid on specs etc but still steam up. Very annoying in shops (sorry everyone who has to go round me while I wipe them lol) but prob even more so if this happens during actual eye test. I may try asking a few local opticians what their procedures are. Otherwise I’ll have to stick to scratched and tired glasses for a good while yet, boo hoo!
