…really? I have prescription glasses/sunglasses and I often don’t bother switching them during a quick excursion- such as daycare pickup/drop off. It’s never crossed my mind that I could be perceived as rude. I’m going to go out on a limb here and say that anyone with such opinions do not have the level prescription that are required for driving and just general consent use. And for anyone thinking transition lenses would be the solution- those do not work in vehicles with UV blocking windows.
