How to protect your eyes when looking at computer screens a lot

Sitting at the computer too much is harmful to your eyes.

Especially during the current period of social distancing, people have to study and work online, so the frequency of contact with computers and phones has also increased. So how to protect your eyes to stay healthy. Let's refer to the following ways to protect your eyes:

20 - 20 - 20 Principle

Why is it called the 20-20-20 rule? It's simple. Every 20 minutes of working on the computer, you should spend 20 seconds looking 20 feet away (1 foot <=> 30.4 cm). This will help your eyes rest properly and not be under too much pressure.

Keep your distance

When working, studying or entertaining for long periods of time with a computer or phone, pay attention to keeping the distance from your eyes to electronic devices at about 50 - 60 cm, eyes 10 - 20 cm higher than the screen and 30 - 40 cm from the keyboard.

In addition, when sitting to work or study, try to keep your back straight, and place your hands on the table so that your elbows are parallel to the ground. You should choose a work or study space with enough light, not too dark or too bright.

Stress-relieving eye massage

Every 30 minutes, take a break from looking at the screen and massage your eyes. You can stand up to rest, stretch or make a phone call. Here is how to massage your eyes:

Step 1: Rub your palms together quickly for 8-10 seconds. The friction creates a small amount of heat.

Step 2: Close your eyes, place your right palm on your right eye, and your left palm on your left eye for about 1 minute. Do not press on your eyeballs with your hands, just place them gently on them. Breathe in and out slowly to relieve tension. Repeat the above movements 2 to 3 times.

Reduce screen brightness and adjust resolution accordingly

Leaving the screen too bright will strain your eyes, and for a long time will make the eye cells work at full capacity, easily causing symptoms of eye pain, watery eyes, and stress. You should use the brightness and contrast adjustment buttons to adjust the screen to suit different times. To create the most comfortable feeling for your eyes.

Blink often

When we stare at a computer or phone screen, we often forget to blink. This causes our eyes to dry out. It’s actually quite difficult to remember to blink regularly (because when we’re concentrating on work, we often don’t think about much else), but remembering to blink will help keep your eyes from drying out and reduce eye strain.

In addition, to keep your eyes healthy, establish healthy living habits and limit the amount of time you spend watching your phone or computer before going to bed. Remember to clean your eyes regularly and supplement your diet with foods that are good for your eyes, rich in vitamins A, C, E and Omega-3, such as meat, fish, and green, red or yellow vegetables and fruits.
