It's imminent that computers make our work easier and more efficient, but on the other hand computers also affect our health at the same time. According to experts, 70 to 75% of those who work or sit on a computer have vision problems. This condition is called "computer vision syndrome". Sitting for a computer for more than three hours a day poses a potential threat to the development of a computer vision syndrome.

Although, for now, there is no reliable evidence that the use of a computer leads to permanent damage to the eyes, these symptoms can be a significant problem.

Visual disturbances and changes in the eyes

Within the computer vision syndrome, visual disturbances may occur in terms of difficulty in focusing, color perception changes, light sensitivity, text flashes. Frequent feeling of dryness, redness, itching, burning, increased tiredness, feeling of weight in the eyelids. The sensation of the foreign body in the eye is particularly noticeable in the contact lens carriers.

Preventive measures

In order to alleviate or eliminate the problems caused by long-lasting work on a computer, we propose:

Adjust the brightness of the monitor to the intensity that your eyes give,
Restrict continuous computer time.
Apply the rule to look at 20 minutes every 20 seconds.
Use special filters in glasses or to reduce the glare. Wearing special glasses designed to operate on a computer reduces eye strain. They may also have dioptres, if necessary, which an ophthalmologist will determine, and it is desirable to have an antireflex layer.
Be sure to visit an ophthalmologist

Meet your ophthalmologist with any eye strain or other problems you feel at work or when working with a computer. You may need glasses or contact lenses to correct vision and ease your work on the computer. Glasses can be:

Monofocal and will provide you with a good vision only at one, fixed, distant or near distance of about 35 cm.
Multifocal glasses provide a good distance and proximity view as well as the intermediate distance just needed for working on a computer.
By bifocal principles, a good distance and proximity is achieved. at 35 cm, but due to the direction of looking at work on the computer, the use of these glasses requires a forced, unnatural position of the head backward, which creates a fatigue in the neck area and feeling disconnected, so they are not recommended for operation on the computer.
Glasses can have a tinted (photosensitive) and antireflective layer, which can help to enhance the perception of contrast, filters glare and light reflection in order to reduce work disturbances.

Parents should contact a doctor in case you notice that the child flashes, has red eyes, if they complain of tearing, blurred vision, eye fatigue and headache.
Computers used by your children should be set at an adequate height and with optimal lighting in order to reduce the problems.

With the right choice of computers, the position of your body in relation to the screen, the proper working and resting, using, if necessary, adequate spectacles, you can reduce or eliminate the symptoms of computer vision syndrome.

It is recommended to check your and your child's sight at least once a year with a specialist doctor. In case any of the above symptoms occur, it is best to contact the ophthalmologist immediately
