Another thought to consider - orthokeratology. My kids and I wear Ortho K lenses. They're gas permeable lenses that you wear to bed. While you sleep, they reshape your corneas, and when you wake up, you take them out and have perfect vision all day. I love them! The best part about using them with kids is that they keep their vision from changing. My oldest has been in them for two years and his vision hasn't changed a bit in two years. I have horrible vision and wanted to do whatever I could to keep my kids' vision from getting as bad as mine. It's a great solution for athletes, because it literally changes nothing. I actually heard about them when I read an interview with an elite gymnast. There are not many doctors who do orthoK, so you have to go to a good one, but it really is life changing to use them. If any of my other kids need glasses, we won't even bother, we'll just go straight to the lenses and never consider anything else.
