Digital eye strain is increasingly common in our screen-dominated world. If you spend hours looking at computers, tablets, or smartphones, your eyes are working overtime.

This gives your eye muscles a chance to relax and helps prevent the fatigue, dryness, and headaches associated with prolonged screen time.
