Is there any way to slow the deterioration of vision? HELP!?

Hello, I'm 17 years old and I have very poor vision (I wear both glasses and contact lenses). In terms of dioptics (or whatever the scale is called) my prescription is a -10. In case you don't know what this is like, I have to get about 2 feet away from my digital clock near my bed to read the time.

Since I was 7 my vision has gone down about -1 per year. I'm worried that it will get to a point where there will not be any contact lenses available for my prescription.

I have NO idea how to slow down the deterioration rate of my vision. It's becoming a very big concern for me. Particularly, I'm very worried that my nearsightedness will lead to diseases/glaucoma/retinal tear, etc.

PLEASE give me some advice on what kinds of foods to eat, eye exercises, etc. to slow down the rate (if it will ever stop) or help keep my eyes healthy. THANKS!

My vision is 20/400, which is really poor. I recently started doing the exercises to try to improve my vision. I created a blog where I record my progress with the exercises.

I recently saw some improvement. Other people (who have also experienced improvements) have posted comments about their experiences as well. You can check it out at: http://improvingmyeyesight.com/blog

Hope this helps....

First, you HAVE to get to a reputable eye doctor immediately. If you can't afford insurance, go to the Lions Club homepage and locate a chapter in your area. Then call the number and find out when their "eye mobile" will be available for free exams. DO THIS IMMEDIATELY. It may take you a while to be seen. Good luck to you. BTW, I am a Lions Club member because they helped me and I wanted to pass it on. Melinda
