I haven prescription sunglasses. Generally I don’t wear them inside, occasionally I’ll forget that I have them until after I’m in the store though. My eyesight without glasses is terrible so I leave them on. Sorry if I look like an asshole but I would have trouble navigating my way and finding what I need without them.
I guess I never noticed. I always wear a ball cap when driving, always have before wearing glasses. Just another tool I use and have not given it much thought.
They will also go dark when it’s overcast outside because they react to UV and not visible light. So your glasses will get dark when it’s already cloudy, which is not great
