While it seemed like a fun prank at the time, I realize my prank fire extinguishers full of leaded gasoline were a mistake.
why is it considered a bad idea?
I could never get a straight answer. I think it's fashion.
If it’s the women in your life, then yes. They are the epitome of turbo-dork when it comes to eyewear.
You know, we're generalising, but you've got a point. None of my male friends have glasses in any kinds of shapes other than "boring grey ovoid."
I have to wear them every day with any outfit at any occasion, it sounds silly to choose something flashy.
It’s not the shape, it’s just the transitions themselves. Aesthetically, sunglasses have a handful of popular styles. Whatever frames you have for your regular vision correction, most likely aren’t one of those styles.
They work based on UV light. So they will not transition inside cars. They also will not transition in cold weather, so you'll walk in snow with clear glasses and have dark ones for 5 minutes once you go inside.
Never had them not work in cold. They change even during heavy snowfall when it's well below freezing and well, no sun, heavy clouds. It's great because they help with the glare from snow.
