I am 17-years-old and I wear contacts with glasses as my backup. I am currently wearing prescribed lenses. Although I may be young, my vision is at it's worse. I wear -6.75 prescribed lenses. My doctor says the strength of prescription glasses reaches higher, but, at my age, that is extremely high. If I do not have my contacts or glasses on, I cannot see objects unless I am 3 inches away from them.

I know vision loss can be due to excessive use of many electronics. For instance, the computer and the tv. I use the computer often, but, compared to my friends who use the computer twice as long as me, my vision continues to deteriorate at an alarming rate. Why is that?

I am worried that by 30 I will be blind. I doubt that this is some type of disease, but I just need some advice to keep weight off my eyes. What can I do?
