Recently, people who spend a lot of time at the computer begin to notice that their visual acuity is deteriorating, double objects appear, the release of tears increases, a feeling of mote under the eyelids, pain appears in the eye area, eyeballs look inflamed. The manifestation of these symptoms is called computer vision syndrome (CCS).

Statistical studies have shown that CHD is observed in 75% of people who spend several hours at the computer every day.

What is the reason for the harmful effects of communication with a computer on human vision

The brain and visual organs of a person perceive the image from the monitor screen and the image located on paper differently. The text on paper is crisp, while the letters on the computer screen are not crisp and clear.

Images on a monitor are formed using tiny dots of light (pixels) that are usually brighter towards the center than at the edges of the screen. These nuances make it difficult for the eyes to focus, which leads to an overload of the visual channel during work.with a computer. Also, blue-violet radiation generated by monitors has a negative effect on eye tissues.

Besides this, with concentrated attention on the screen, a person blinks much less often than usual. At the same time, the work of the lacrimal glands is disrupted, protective, nourishing and light-refracting functions deteriorate. This leads to dry eye syndrome.

Due to the above negative factors, it became necessary to protect the eyes from the harmful effects of the computer on vision.

What measures to take from the harmful effects of the computer

Is it possible to abandon the computer in the era of information technology, when it has become indispensable both at work and at home? Of course not, because now no organization or institution can do without a computer.

There are no age restrictions for regular computer users. Now a significant part of the day at the computer is spent by people from 6 to 70 years old. How can you protect your eyesight from the harmful effects of a computer?

Computer glasses - eye protection

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

They have special lenses designed to reduce the development of symptoms associated with CVD.

A special interference filter is applied to the surface of the lenses of computer glasses, which absorbs the rays of the blue-violet spectrum. The optical characteristics of thiscoatings increase the resolving power of the eye, which leads to a decrease in visual load.

Computer glasses have no contraindications. Glasses with lenses without diopters are produced for users with normal vision.

For those who constantly wear glasses with diopters, you can pick up ready-made computer glasses in optics or go to a specialized salon where they will make glasses for a computer with the necessary parameters, they will pay attention to all your wishes and feedback.

Computer glasses are an important accessory. Let's take a closer look at the selection of glasses for the computer. To ensure comfortable work at the monitor, lenses for computer glasses of several types are made, which we will talk about.

Monofocal lenses

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

Bifocals

The upper half of these lenses is aimed at focusing on the computer screen, and the lower half is adapted for the perception of objects at close range. These lenses show a boundary separating two optical zones. Although these lenses provide comfortable viewing and reading at close range, distant objects will be perceived as blurry.

Progressive lenses

Outwardly they are similar to conventional monofocallenses, since there are no clear boundaries between the optical zones. However, progressive lenses have three segments with different viewing capabilities. The upper zone is designed for viewing objects at a long distance, the wide buffer zone is for working on a computer, and the lower part of the lens is designed for focusing at close distances. This type of lens is the most comfortable, as it allows you to see clearly at any distance, feeling more natural.

Glasses for a computer, reviews of ophthalmologists confirm this, minimize the harmful effects on the eyes from fluorescent lighting lamps due to their properties not to let through blue-violet rays that negatively affect the eyes. On sunny days outside, a special coating of computer glasses will reliably protect against ultraviolet rays. In this situation, anti-glare computer glasses bring double benefits to their owners.

How to choose glasses for working at a computer

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

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

For gamers, lovers of dynamic scenes, anti-glare glasses for a computer are suitable, reviews of such accessories can, of course, be viewed on the Internet, but it is better to buy optics for working with computers in special stores.

Buying optics over the Internet is undesirable, as there is a high probability of acquiring a fake. Price is not an indicator of quality, but this criterion should not be discarded either. In order not to pay twice, it is better to spend money on high-quality computer protective glasses. User reviews indicate that glasses from German, Japanese and Swiss manufacturers deserve more trust. 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, a lot of attention is paid to their appearance, but if you choose glasses for a computer, customer reviews, of course, play an important role, but the quality of the accessory will be a more priority choice. You can familiarize yourself with 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 protective functions. Protective glasses are made with diopters and with ordinary lenses. For PC users suffering from nearsightedness or farsightedness, it is better to order special lenses for working at a computer with the right diopters.

What should be the frame

If you look at the reviews, computer glasses are now in demand, and we can conclude thatThe best option for the material for the frame can be good plastic or high-quality metal. When choosing an elegant metal frame, it is better to make sure that it is of high quality, otherwise the coating of the frame will begin to wear off rather quickly. This leads to oxidation of the frame metal due to skin contact, which can cause allergic reactions and irritation, as well as dark spots on the skin where it comes into contact with the metal, which is often what users pay attention to when leaving reviews.

Computer glasses have a rather high cost, which is due to the high quality of all components, polishing quality, proportions, and reliable fastenings.

Gunnar glasses

The lenses are equipped with optical anti-reflective filters developed on the basis of GUNNAR i-AMP technologies.

The use of yellow color and anti-reflective coating in the lenses was the best solution for increasing the contrast of the perceived image from the monitor and significantly reduced the effect of bright lighting on vision used in offices.

Real protection of computer glasses

The opinion of most ophthalmologists is unequivocal - such glasses really relieve fatigue, prevent the occurrence of headaches associated with the eyes, and prevent visual impairment. It must be remembered that you will not get rid of all eye ailments by buying glasses. Protection from the computer, user reviews say this, of course, there will be, but computer glasses only reduce eye strain and make working at the monitor more comfortable and safe, but they are not able to save from visual impairment if the rules of caring for one's he alth are violated.

Vision monitoring, work breaks

In addition to the use of protective accessories, you must constantly monitor the state of your vision, periodically letting your visual organs rest. Invisible screen flickering is quite tiringfor eye perception when viewing pictures on modern monitors. It is advisable to take a break from work, use gymnastics for the eyes, relax, even if you are wearing computer glasses. Reviews say that the most effective way to relax is he althy sleep.
