I was 12 when I first got my contacts, and it did improved my vision. I've worn different types from tinted to regular clear to clear with glasses over them and now I am wearing the istigmatism ones.
I had a bad reaction with my eyes and the tined ones. They were too think and very uncomfortable. My eyes were always watery and my eye lids got bumpy underneath them...ew
The istigmatism ones are amazing. I went down two more lines on the eye chart. With contacts i was also given proifrial (sp) vision, which helped a lot in making my vision better.
10-1 years old are the best times to get contacts, I believe. Talk to your doctor about them, I started talking to mine when i was 9 and we went through it a few uears later
good luck!
