I'm 35 now. Two years ago I was 20/400. To read a book, it had to be 2-3" from my face to make it legible without corrective lenses. I really did consider myself legally blind, as without glasses or contacts, I was screwed. At the pathetic state of 20/400, if I were walking down a sideawalk and a good friend passed by, I would not recognize them. It was that bad.
THEN, I elected for lasik surgery. I am now 20/10 with both eyes open and no detectable side effects. My best corrected vision with lenses prior to surgery was 20/20.
I see everything now.
It was the best $2000 I ever spent. I really doubt I will ever get that much bang for the buck ever again.
The procedure itself was creepy as hell. You will smell your burning eye, and it smells like burnt hair.
If your poor eyesight gets to be a true burden as mine was for so many years, since I was 14, consider surgery.
I was in a utter state of amazement for so long, and I still am when I think about it every so often. You would be too if your vision was/is as bad as mine was.
