Just an FYI, I had that happen to my driving glasses a couple years back. My optometrist said that's because you cannot leave glasses in a hot car as the heat destroys the coating... OK thanks for telling me AFTER the fact, where do you THINK I am keeping a pair of glasses that you designed specifically for my driving vision? And by the way, I've been wearing glasses for over 35 years and always had the anti-glare coating for night driving, what did you change that is suddenly making them self-destruct when they are stored where I need them???

Yeah they had no answers for me. But OP, if you left your glasses in your car, that's probably what happened to the coating.

Just an FYI, temperatures in a car in direct sunlight can exceed 165F. Very quickly.

I know this because I left a glass thermometer under my seat for an hour one summer. When I came back to grab it, the glass has burst (max on the scale was 165F).

I have no idea about lens coating changes over time and their heat tolerance, but the insides of cars can be fucking awful.

TIL what happens when the thermometer maxes out
