Is there no way to avoid spending hours and hours each day staring at a screen? Apart from the 20/20/20 rule one tip is to make sure your screen level isn’t higher than your natural gaze.
When you need to spend the majority of every day staring at a screen you should be making sure you are doing so in the safest way possible. One tip for positioning your computer monitor is to adjust the height so that it’s slightly below eye level. Ideally, you should be approximately an arm’s length distance away from your screen and your gaze should look slightly downward when looking at the center of your screen.
This is because if you are looking straight on or even slightly up more of your eye is exposed to the air. Overtime, with a decreased blink rate from staring at a screen, this could lead to eye dryness and uncomfortable symptoms.
