Hello, I am 14 years old and my eyesight is really bad. My doctor told me I can’t improve my eyesight and can’t watch screens for more than 1 hour a day. And I got -4 myopia when I tested it 1 year ago. Now I think my vision decreased even more. So when I was 9 years old I used to watch to much tv and got -.75 myopia. Then when I was 12 years old I had phone addiction and used phone for 6 hours a day and got -2.25, -2 myopia and then after online classes it doubled to -4. I still watch phone and play videogames but take more precautions like blue light filter lowering brightness on tv less blue light etc. Please someone tell me how I can improve my vision.
