When I was playing with lasers back in the 70s even the class 3 helium neon lasers we had strict warnings and eye protection.
The argon and co2 lasers had restrictions that were super strict.
I would probably never purposefully let a laser vaporize part of my eyes.
Well millions of people worldwide have had it done with no ill effect.
I got Lasik on both eyes when i was 54. Had one eye set for distance, and one eye set for reading (monovision). Zero regrets. I had worn contacts / glasses for 40+ years and couldn’t wait to be done with them.
