While it seemed like a fun prank at the time, I realize my prank fire extinguishers full of leaded gasoline were a mistake.
They transition very quickly though. Takes like a minute
I work from home in an office garden. The walk from the house to house to the office was enough to transition the lenses and then you're wearing sunglasses for 5 mins and they slowly change back. Definitely takes longer than 1 minute.
Interesting, yeah, I don't mind them as much I guess. Now I'm considering just getting prescription sunglasses to wear all the time
