You have something called as computer vision syndrome.
So take frequent breaks while you are working
Every 20-25 mins take break to look away from screen
Blink more frequently'
Level of screen should be below the level of eyes
Ac should not blow directly on your face. Also get
your eyes checked for any spectacle power
Here are the instructions for mobile
Here are seven super quick
and easy ways to give your eyes a break during your all those smartphone marathon sessions.
1. Blink, blink and blink again. Blinking often (and for more than a second) keeps your eyes moist and reduces dryness and irritation. We tend blink about a third less than we normally would when we stare at our smartphone screens, which starves our poor peepers of protective tears. Keep your eyes wet by blinking about 10 times every 20 minutes or so and you should be good to go. 2. Minimize glare. Unless you have a smartphone equipped with anti-glare Corning Gorilla Glass or use a matte screen protector film, you’re probably coping with a fair
amount of annoying reflective glare. 3. Take breaks. Follow 20-20-20 rule. The concept is to take a break from looking at your screen every 20 minutes for 20 seconds while looking at something 20 feet away. Doing so relaxes your eye muscles 4. Adjust your brightness. Having your screen too bright or too dark stresses your eyes out and can cause problems maintaining focus. To eliminate
either issue in about a matter of seconds, simply
go into your smartphone settings and adjust your screen brightness so it’s about the same as the light level in the environment around you
5. Tweak your text size and contrast. Adjusting your smartphone text contrast and size also provides a little much-needed relief. 6. Keep a clean screen. Routinely wipe down your smartphone screen with a dry (not wet!) cleaning cloth to remove distracting dust, grime, smudges and fingerprints.
7. Hold your smartphone farther away. Try holding yours at least 16 to 18 inches away from your eyes to give your eyes a break.
