How do you protect your eyes from straining?

Adjust the brightness.

Whether looking at the phone or Whether it’s watching TV or watching TV, if you get enough light, your eyes don’t have to strain too much. If you want to read, let the light reach the paper.

Do not fire directly into the eyes. Adjust the brightness of the phone and computer properly.

If you use a computer, keep it an arm’s length away from you. Keep the screen level with your eyes. So there will be no tension. Use a large font size so as not to strain the eyes.

Take a break.

Use the 20-20-20 rule. Look 20 feet away for 20 seconds every 20 minutes of using your phone. So that I can rest my eyes and continue watching.

Set a time.

Instead of using it continuously, I set what to do after how long I use the phone.

blink.

Artificial tears, which can easily be purchased, can prevent dry eyes. If your eyes become dry and itchy, blink. Read the label to find out how many times to whip.

Take care of the air around you.

If you open the fan directly in front of your face like I just said, If the air conditioner is turned on, the eyes are often dry.

So if you’re straight, move your seat. If you stay in an air-conditioned room for a long time, your skin will dry out as well as your eyes. Turn on the humidifier.

Wear glasses that fit you.

Sometimes, if the glasses don’t fit, the eyes have to work harder to see clearly. So wear glasses that suit you. Power back up if necessary.
