5 ways to help your eyes "cope" with computers
According to a study in the US, more than 90% of computer users suffer from visual disturbance syndrome and eye diseases. And to limit this condition, you need to note:
CVS-this visual disorder syndrome can affect all people who work with computers for many hours or just two hours a day, regardless of whether they are computer professionals, office workers or students.
Because working a lot on the computer requires high concentration, causing increased tear evaporation, dry eyes and eye strain.

And to prevent signs such as tired, stressed eyes; feeling of dry eyes, hot eyes, sticky eyes or foreign objects in the eyes; blurred vision, sometimes headaches or pain in the eye sockets; in the long term, neck pain, back pain, you need to pay attention to:
Blink
When using a computer, the eyes must open wider, the number of blinks is only about 6-7 times/minute because the eyes must focus on a point at a close distance.
Normally, the average number of blinks is 14 times/minute. Blinking helps the eyes spread tears evenly over the surface of the eyeball to keep the eye smooth, clear and remove dirt on the surface of the eyeball.
When you blink less, your eyes will become dry and blurry, like a car windshield that is covered with dust and not cleaned.
Computer quality
The light from the computer screen shines directly into your eyes, causing eye fatigue. If the computer screen is of poor quality, the light is easily flickered and shaken, causing eye strain. Dust on the computer screen also affects light reflection.
Therefore, it is necessary to pay attention to adjusting the screen's light contrast, adjusting the surrounding light so as not to glare the screen. There should be a plan to clean and maintain the computer regularly or use a screen protector to limit the impact of rays on the eyes.
Choose a computer with a large, flat screen and check the contrast and adjust the brightness of the screen to an appropriate level.
Actively control light
Change the lighting around you to reduce glare on your computer screen.
If it is natural light from a window, move the screen until the shadows disappear.
Use a desk lamp with a dimmer switch to adjust the light to suit your eyes. Be sure to choose a lamp that distributes light evenly.
Placing a glare filter on your monitor screen can also help protect your eyes.
Suitable distance
If the distance from the eyes to the computer is not suitable, such as the computer is too close to the eyes or too high, the eyes will have to look up frequently, so they will have to adjust more, open wider, and the eye muscles will work more, causing fatigue.
You should sit 50-66 cm away from the computer screen and place the screen about 10-20 degrees below eye level, do not let the screen center too high or too low compared to eye level. Working posture is also very important, remember to always keep your back straight and your shoulders level. When sitting, you should adjust the chair so that your forearms are parallel to the floor, your thighs are perpendicular to your shins and your feet are flat on the floor.
Eating and resting
After every 20-30 minutes of working in front of the computer, you should rest your eyes by closing them, or looking into the distance, especially at green trees or looking around the room for about 20 seconds. You can also do some relaxing movements, massage your eyes to feel more comfortable.
Several studies have shown that a diet rich in the nutrients lutein and zeaxanthin may help prevent eye diseases such as macular degeneration and cataracts.
Nutrients that are good for the eyes such as natural vitamin E, vitamin A, vitamin B2, Lutien, Selenium, Chondroitin, Superberry extract can be found in fresh foods every day such as red, orange, yellow vegetables, shrimp, fish, meat... or in some functional foods for the eyes currently sold on the market.
When all of the above solutions fail, see an eye specialist and tell him or her about any eye strain or other problems you are experiencing at work.
