From past few weeks whenever i read a text from a book, computer or mobile phone i see 3-4 horizontal lines in my vision when i look at a wall ( some dark place with less light especially) after reading. It disappears after 4-5 seconds but its the first time i am experiencing something like this. I was diagnosed lattice degeneration 2 yrs prior as i have floaters in my both eyes. From past 2 years i am in regular check up. This time i went to the doctor he said it's because of excess time i spent on screen but i am seeing these lines even if i look at screen for 10 seconds or read a book for few seconds. What should i do??
