Types of glasses to work on the computer
Today, manufacturers offer different glasses for the PC.Given the different health conditions of the eyes of each person, firms produce several types of safety glasses:
| Kind | Description |
| Monofocal | Allow to perceive the image completely, but the person does not need to move his head( the glasses give a full picture and a wide field of view).Monofocal need people who track the content on the screen |
| Bifocal | There are two segments. The upper part is focused on the monitor, and the bottom is needed for a close-up view( in this case, the monitor's view is smaller, head movements down and up much more).Bifocal have focus areas for near and far distance, and the intermediate zone remains without focus |
| Three-focus( trifocal) | There are three segments, the first two are the same as those of bifocal lenses, and the third is responsible for a clear image of objects located at an elongated distancehands |
| Varifocal or progressive | There are three segments. The wide middle zone is aimed at working with the monitor. This is an innovative invention and some ophthalmologists believe that these lenses are the best option for |
. The disadvantage of progressive lenses is the need to raise your head to see the image. The zone outside the monitor is located beyond the area of "clear" view. For people with age-related changes( presbyopia), variofocal lenses should be selected.
Eyeglass lenses can be polymer or glass. The main function of glasses is to block radiation. Both kinds of lenses cope with this. Glass - heavy, so do not fit people with poor eyesight. To turn them into "computer", manufacturers apply a special protective coating on the lenses.
Polymer weighs less and does not give a load on the nose( there will not be any marks left from the rim, even if you have a "big" minus or plus).Plastic lenses consist of several layers. One- and two-layer protect from radiation. Multilayered give protection from radiation, improve image sharpness, give additional clarification.
How to choose the glasses for yourself
In order to guarantee the correct glasses to work for a PC, you need to visit an ophthalmologist and find out what the state of your eye's health is at the moment. People with normal vision are suitable monofocal glasses.
People with myopia or farsightedness are suitable for bifocal or trifocal glasses.
The upper half will better focus on objects. The lower one will make it possible to clearly see the objects near.
Progressive lenses are expensive, but they fit almost everyone. When choosing glasses for a PC, it is important to pay special attention to the quality of the frame and lenses.
Give preference to lenses from Switzerland, Germany, Japan, France. Their value is higher than most market offers.
According to doctors, it is also necessary to fight with dry eye syndrome. Behind the PC monitor, a person concentrates his attention so much that he stops blinking. As a result, dry eyes appear, which provokes redness, burning, weakening of vision.
People who complain about computer visual syndrome, recommend wearing glasses and doing gymnastics to prevent eye diseases.
Other people are neutral about the use of glasses. The reason for this is improving the quality of monitors. Modern screens have a special protective mesh, which protects against radiation.
Therefore, they do not harm the eyes. But the glare from them is not completely eliminated, so working with glasses can cause a slight decrease in fatigue in the eyes.
When you need glasses for working with a computer: recommendations from experts
An ophthalmologist thinks that protective glasses for a PC monitor do not help people with nearsightedness, farsightedness, they are contraindicated for people with glaucoma, retinal diseases.
When deciding whether you need special glasses for a PC or not, remember:
- it is absolutely necessary to visit an ophthalmologist before ordering glasses;
- the order needs to be made out only in the specialized shops of optics and the centers of correction of sight;
- glasses must be made to order( individually);
- should not be saved on lenses and frames;
- universal lenses that fit absolutely everything does not exist.
It is also important to combine rest with exercises( palming) and gymnastics for the eyes( according to Bates, Zhdanov ) and perform such actions:
- rotate your eyes open to the right and left;
- look with open and then closed eyes( right, left, top, bottom);
- quickly blink a few minutes in a row( to protect eyes from dryness);
- eyelids close and lightly massage their fingers( do circular motions).
Important: if you feel pain in the eyes or discomfort, you need to urgently go to the doctor and give up glasses.
Prices for glasses for PC
Single-focus can be purchased at a price of $ 10.The average cost of bifocals is $ 15-20.Trifocal will cost at least $ 20-25.Progressive costs from $ 50-60.
It's unambiguous to say how much glasses are cost for a computer, becausemuch depends on the quality of the lens, frame, brand and thickness of the lens( ultrathin at least $ 70).
You can not save on the rim, because the headache can arise because of poor concentration of vision or an uncomfortable frame. Therefore, glasses should be chosen with a special protective function and pick up accessories only in specialized stores of optics or centers for vision correction.
Opinion of people about computer glasses: review of reviews
Those who already use glasses for PC, differently speak about these accessories. The opinion depends on how the person picked up his glasses to work with the monitor. If the choice was made without the involvement of a specialist( without a prescription), then the reviews are usually negative( the eyes hurt, quickly get tired, the problem is not solved).
When a person buys glasses for a PC after consulting with an ophthalmologist and chooses this accessory on the recommendation of a doctor, the reviews are often positive: users note that the eyes are less and less tired, there is no discomfort, rarely there are redness or even disappear, do not worry about a headache.

- can not unequivocally say that poor eyesight is the result of working at a computer;
- any, the more healthy the eyes need to protect from the glare of the screen;
- the correct choice of glasses can be made only after a comprehensive medical examination;
