For about two weeks now, I have difficulty looking at the mobile phone screen and my eyes hurt. Then I went to the hospital where my vision was 6/9 and they told me to use glasses but I can't do it and I suspect that my eyesight is deteriorating for about two weeks but now I can't look at the mobile screen. It's so difficult i'm suffering mentally because of this can I cure my eyes without glasses i'm 17. Will I have to wear glasses for the lifetime?
