How did we as humans discover we could this? 😭

This guy turned his eye into a flashlight

I heard that if you don't pay attention to maintenance after the operation, you will be nearsighted again, and your eyes will feel inexplicable pain after the operation.

I had PRK corrective Lazer eye surgery 20ish years ago while I was in the military. (this video looks like the same process).. I'm 46 today and still have 20-10 vision. (Better than 20/20)... In contrast I was 20/400 (-5 prescription ) prior to the surgery. Love it

This doesn't look pleasing to the eye.

I blinked 5 times watching 👀

How are they not blinking

Eye don’t know

They first start testing on dead body . Then those people who have similar issue . After a lot of experiment here we are

LASIK has one of the highest success and satisfaction rates of any elective procedure, with 96% of LASIK patients reporting high satisfaction after treatment. Effectiveness studies show that 70% to 90% of LASIK patients achieve 20/20 vision or better after treatment.
