As for lasik - I blogged about it back in the day - https://medium.com/@ivankerin/a-humble-mans-account-of-the-l...
The problems - one mate didn’t properly understand the commands he was given, (not a native speaker) and ended up poking his eye sort of mid operation. They fixed his good eye, and told him to wait for a couple of weeks until the “flap” healed and regrew so they could do it again on the other eye. Totally avoidable if he was paying attention - I had no problems and it was over in like 5 mins.
Another mate didn’t get corrected to the exact focal length so they had to do it again a couple of months later. Not a big deal just unpleasant.
I decided to go for the operation after I had an eye infection and figured I was risking my eyes every time I was putting the contacts in, so might as well risk it once and be done with it. Glasses were not an option as I wanted (and still do) practice various sports, and -7 is not fun at all.
I do this every day over years now "just in case it works" - hasn't helped me at all. Wish I could believe these delusions.
Have two pairs of glasses, one of them about half strength(self test for the exact number) for computer and close up work or in-home. Use your full strength glasses for important tasks like driving. Every 20-30 minutes take a break and look into the distance(works well with Pomodoro technique, if you do that), practice your blurring exercises.
Edit: at .5 adjustment I'm right at the edge of variance. It's possible to do nothing and have a slight improvement on your yearly optometrist visit because of secondary factors like change in environment or nutrition. I'm not a health expert so I can't say, but if anything that site helped me to do fewer things that strain my vision and a few things that made me more comfortable. Would I have fully cured if I kept going? Science says probably not, but I don't regret my effort.
Near work imposed in schools and wearing glasses constantly is the reason for current myopia epidemic as can be evidenced by low myopia rates in schools following western curriculum that is more holistic in nature.
Glad Lasik worked out for you. What side effects did your friends experience? I've thought briefly about Lasik, but I have this (potentially irrational) fear of persistent headaches as a side effect, which would be a nightmare for me. So I stick with spectacles - it has no detrimental effect on my life, but I do wonder if it would be possible to get back good eyesight again.
