Blink frequently

(If possible, rinse your eyes with water.)

Another way is to blink frequently every time you use your phone. Doing so also reduces eye damage. Blinking is the only way to use a desktop computer. Use only laptops. This is a good practice for tablet PCs.

Focusing on the screen without blinking can cause dry eyes. Therefore, by applying eyelashes, you can prevent dry eyes naturally. Blinking also reduces the amount of radiation emitted by smartphone screens.
