What single item improved the quality of your life over you got it? (Buyed it/got as present/made it)

As in lenses for your face, or drinkware?

Either way, yes.

I went through a glasses addiction myself as well lol. I found an eye-care clinic where they would cut the lenses and have them ready within 3 hours.

I would go to garage sales, thrift stores, and swap meets to find glasses to put lenses on. They were like $60 for the lenses and I never spent more than $10 on frames.

I ended up with 3 seeing glasses and 4 sun glasses before I realized it was going to be unsustainable to get new lenses for my new prescription every year.

Addicted is a good way to put it. I suffer withdrawal symptoms like dizziness and nausea when I go more than a few waking minutes without my glasses.
