I sit in front of computer/mobile for almost 10 hour a day in which I stare at the screen 4/5 hours straight without break as attend online classes or doing some reading. I spent 3/4 hours straight reading at night on tablet. I get 6 hours sleep at night and at least 45 min sleep during day. This schedule is being followed by me for almost 2 years. Because of it my eyes get dry and eyes start to burn. Even if I am not looking at screen it gets dry and burn. Sometimes I get blur vision as well after staring at screen for long time. Please tell me what I should do. Thank you.
