I got LASIK when I was 19. Doctor at the time was like "You may want to hold off since you're still growing." I said "What do you know doc, shut up and slice me!"
So imagine my surprise when I'm going to get glasses 12 years later, and they've now got all these fancy machines doing shit. My eye appointments in my teens were dark room, eye drops to dillate, read some letters, then the thing with the lenses "which is better, 1 or 2?"
Now you go in and hit machine after machine after machine, and that house/balloon decides when it's clear for you. Really incredible shit.
