Prolonged work on the computer causes tension, dryness, and eye fatigue, and understanding the details of this condition helps to reduce this negative effect.
It is normal for any activity related to eye strain to cause, and when activity increases, causes headaches, dryness, eye fatigue, and blurred vision.
When you look at the computer screen, some feel uncomfortable, which is called "visual fatigue," caused by lack of eyelashes when working on the computer, which makes it more dry and tense, according to the American Academy of Ophthalmology .
It is important to rest the deviated eye of the screen according to the "20-20-20" rule, ie, rest for 20 minutes of work and look at 20 feet (20 meters) for 20 seconds.
Reducing the brightness of the screen also helps reduce visual fatigue. Special glass can be used to reduce light reflection.
You should avoid sitting too close to the screen. Ophthalmologists recommend that the top edge of the computer screen be below eye level, and if the letters are difficult to see clearly, they should be enlarged to be clear.
Although there is no scientific evidence that the blue light emitted by the apparatus screens damages the eyes, it actually affects the daily rhythm. In other words, if a person has a sleep disorder, he should leave these appliances before bed.
