I am 35 years old I have a lazy right eye from childhood. However it was detected only when I was 12 yrs old. I had my lazy eye treated with a patch but not much changed. Since then the vision in my good eye has deteriorated from perfect vision without glasses (year 2000) to + 4.25 (year 2013). I studied computers when I was young so was in front of computer for 10-12 hours a day. Is it normal. How can I safeguard vision in my good eye?
This is a large change in the good eye but I suspect it was always longsighted but only with age now needs correcting. You can only safeguard your vision in the good eye by obvious precautions with regard to physical protection and regular eye tests to ensure your prescription is up to date and the eye remains healthy.
