The manifestation of these symptoms is called computerized visual syndrome (GLC).

The conducted statistical researches have shown that 75% of people spend hours on the computer daily for a few hours.

What is the cause of the detrimental impact of communication with a computer on the sight of a person

The brain and human visual organs do not perceive the image from the monitor screen and the image on the paper. The text on the paper has clear outlines, while the letters on the computer screen are not sharp enough and contrasting.

Images on the monitor are formed with the help of miniature radiation points (pixels), which are usually brighter to the center than at the edges of the screen. These nuances make it difficult to focus the eyes, which leads to an overload of the visual channel when working with a computer. Also, the radiation of blue-violet frequency, generated by monitors, also has a negative effect on the eye tissues.

In addition, with concentrated attention on the screen, the person blinks much less frequently than usual. In this case, the work of the lacrimal glands is disrupted, the protective, nutritional and refractory functions deteriorate. This leads to the appearance of dry eye syndrome.

In connection with the above negative factors, the necessity of protecting the eyes from the harmful effects of the computer on vision has appeared.

Computer glasses - vision protection

A good eye protection when working with a PC are computer glasses, expert reviews also advise users to purchase this accessory.

They are equipped with special lenses designed to reduce the development of symptoms associated with COP.

On the surface of the lenses of computer glasses, a special interference filter is applied, absorbing the rays of the blue-violet spectrum. The optical characteristics of this coating allow to increase the resolution of the eye, which leads to a decrease in the visual load.

Computer glasses are an important accessory. Let's look at the details of the selection of glasses for the computer. To ensure comfortable work behind the monitor, we make lenses for computer glasses of several types, which we'll talk about.

Monofocal lenses

In these lenses, the optical zone allows you to watch the computer screen, providing a wider view. Usually, such lenses are chosen by people with normal vision. But with myopia or farsightedness with such glasses, distant or close objects will have blurred outlines.

Bifocal lenses

The upper half of these lenses is aimed at focusing on the computer screen, and the lower part is adapted to perceive objects from a close distance. On these lenses, a boundary separating the two optical zones is visible. Although these lenses provide comfortable work with the computer and reading near, remote objects will be perceived vaguely.

Progressive lenses

Externally, they are similar to conventional monofocal lenses, since there are no clear boundaries between the optical zones. However, progressive lenses have three segments with different viewing capabilities. The upper zone is intended for viewing subjects at a long distance, a wide buffer zone for working on a computer, and the lower part of the lens is designed to focus on close distances. This type of lens is the most comfortable, because in such glasses you can clearly see at any distance, feeling more natural.

Glasses for the computer, reviews of ophthalmologists confirm this, minimize the harmful effect on the eyes of fluorescent lighting lamps due to their properties not to miss the blue-violet rays that adversely affect the eyes.

How to choose glasses for working with a computer

Choose computer glasses should be based on the type of work on the computer. If the lion's share of the work is related to the texts, it is better to choose glasses with lenses that enhance the contrast and remove the halftone. When working with graphics programs, they will be the best option.

In this case, you should ask the seller in detail about the chosen model of glasses and get acquainted with the corresponding documentation on them. If it is not available, then it is advisable to refrain from buying in this salon.

For gamers, fans of dynamic scenes, anti-glare glasses for a computer, reviews on similar accessories can, of course, look on the Internet, but opticians for working with computers are better in special salons.

Buying optics over the Internet is undesirable, since there is a high probability of buying a counterfeit. Price is not an indicator of quality, but this criterion should not be discarded either. To avoid paying twice, it's better to spend money on quality goggles for your computer. Customer feedback indicates that more points are earned by German, Japanese and Swiss manufacturers. The quality of domestic and Chinese computer optics is slightly lower, but at a price it is more affordable.

Design or quality

When buying glasses for everyday life, much attention is paid to their appearance, but if you choose glasses for your computer, customer reviews, of course, play an important role, but the quality of the accessory will be a higher priority option. You can see the appearance of these glasses by looking at their photos to make sure that they are all identical. They are comfortable to wear, carry mainly defensive functions. Protective goggles with diopters and with usual lenses are made. For PC users suffering from nearsightedness or farsightedness, it is better to order special lenses for working with a computer with the correct diopters.

What should be the frame

If you look at the reviews, computer glasses are in demand now, and you can conclude that the optimal version of the material for the frame can be a good plastic or high-quality metal. When choosing an elegant metal frame, it is better to make sure that it is executed qualitatively, otherwise the coating of the frame will begin to disappear quickly. This leads to oxidation of the metal frame due to contact with the skin, which can cause allergic reaction and irritation, as well as the appearance of dark spots on the skin at the point of contact with the metal, often users pay attention to this, leaving feedback.

The glasses for the computer have a fairly high cost, which is due to the increased quality of all components, the quality of polishing, the observance of proportions, reliable fasteners.

• You need to work at a computer in a well-lit room.
• The location of the monitor is min 50-60 cm from the eyes.
• Required breaks in the work every half hour of working with the computer.

During a break, you need to do an easy eye exercise:

1. The maximum turn with the eyes to the left, then to the right, up, down.
2. Rotation of the eyes in a circle first in one direction, then in the opposite direction.
3. Close your eyes tightly for 5 seconds, then open wide. The procedure is repeated several times.
4. Rapid blinking for 2 minutes. This exercise will moisturize the eyes and save from drying out.
5. A direction of a sight in the distance. This removes tension from the eyes.
6. The eyes are closed, and the eyelids are massaged with circular movements of the fingers.

With these simple rules, the eyes will always be healthy.
