There is some evidence that blue light from screens can be harmful to the eyes, causing digital eye strain. It can also disrupt sleep patterns. To reduce the risk of these problems, try the following:
-Limit screen time in the evening and avoid using screens for at least an hour before bedtime.
-If you must use a screen at night, dim the brightness and use blue light filtering software.
-Take breaks from staring at screens every 20 minutes or so to give your eyes a rest.
-Make sure the text on your screen is large enough and the contrast is high enough to reduce eye strain.
