Glasses with anti-reflective coating. What can glare influences lead to? How is an anti-reflective coating applied to lenses?

Life modern man hard to imagine without glasses. There are several types of them - corrective vision, sunscreen, protecting from rain and wind, or just an accessory in addition to business style. The importance and benefits are truly undeniable. But apart from clear benefits wearing glasses has a number of significant disadvantages. For example, in sunny weather glare may appear on the lens. At office workers it can only cause a feeling of fatigue. Active people, often exposed to direct sunlight, you should still prefer anti-glare glasses instead of standard sunglasses. Consider the main advantages and disadvantages of the accessory.

Anti-glare glasses are especially popular with drivers.

Anti-glare glasses perform several important functions. Positive effect provided by a special lens material. The glasses filter out the reflected rays of light. As a result, the eyes do not focus on the light. Visual acuity is maintained.

The lens structure of anti-reflective glasses is designed to absorb harmful blue rays. Safe for perception (yellow tint) remain. The main advantages of using anti-reflective glasses:

1. Eliminated dangerous impact on vision from fluorescent lamps, as well as a computer.
2. Provides a safe brightness for the visual analyzer.
3. Glasses can increase the contrast of the monitor.
4. It can be used in combination with other means as a prevention of the development of myopia.
5. Protects the retina and lens.
6. Prevent the development of photokeratitis (complex form sunburn with damage to the cornea).
7. Eliminate the main signs of fatigue: redness of the visual organ, increased secretion of lacrimal fluid,.

Prevention of most of these problems significantly improves the quality of life and performance. Negative sides, as well as contraindications for the use of anti-reflective glasses are unknown. A stylish accessory can make life easier for both the elderly and children.

Purpose

The accessory is especially popular among drivers of vehicles. After all, glare of light often dazzles people behind the wheel and leads to emergency situations.

Additionally, glasses perform a corrective function. Therefore, they are prescribed to people with visual impairments. Ophthalmologists recommend wearing them when sitting at a computer monitor for a long time, as well as while using other gadgets.

Choosing glasses for drivers

To choose the right accessory, you first need to decide on the color of the lenses. Manufacturers have developed several simple recommendations for users:

1. Drivers with 100% vision are advised to use glasses designed only for driving. The color, as a rule, for such an accessory is gray. The dimming ratio is in the range of 70 to 90%.
2. If you experience constant eye discomfort from stop - signal lights, as well as traffic lights, choose glasses with green lenses.
3. have universal properties anti-glare glasses brown as well as yellow. The luminous flux from oncoming traffic is significantly reduced. They are able to relieve eye fatigue, as well as improve visibility during bad weather conditions. They can also be used for computer work.

Please note that the quality of anti-glare glasses depends not only on the material of the lenses.

Useful properties of anti-glare glasses for drivers you can learn from the video:

Also pay attention to a few details:

1. The frame should fit snugly around the bridge of the nose, as well as the ears. She should not squeeze her face. At the same time, glasses with a too loose shape can fly off at the wrong time.
2. If glasses with temples located above or below the frame fit the shape of your face, choose this model. Such an accessory will provide maximum visibility (in viewing angles). Peripheral vision is also not limited.

Anti-glare goggles, like other accessories to improve visibility and protect the eyes, do not have an expiration date. Despite this, the duration of their use directly depends on proper care. Manufacturers advise to perform several simple rules:

1. Protects against various damages (scratches, shock) classic case. An inexpensive accessory will help extend the life of your glasses.
2. It is also advisable to put napkins in the case. Use only a special cloth for cleaning. Microfiber is suitable for wiping. But it is also allowed to use disposable handkerchiefs. The soft material will help clean the lens and will not scratch the special coating.
3. For heavy soiling, use warm soapy water. Do not clean glasses with anti-reflective bleach, ammonia, glass cleaner, or vinegar. Special solutions are sold at optics dealers. Pay attention to the composition. The content of antistatic and antiseptic will help get rid of dust, as well as harmful microorganisms.

The anti-reflective glasses do the job perfectly. Their coating can protect the vulnerable visual organ from the influence harmful factors environment and long work at computer. Do not use glasses that are chipped, damaged or scratched. It is very dangerous. Follow a few simple care rules and your glasses will serve you for many years.

A unique layer is applied to anti-reflective lenses, which has the ability to filter out reflected light fluxes, leaving only a safe sector yellow color. Such eyepieces completely absorb the harmful blue rays. This is very important factor since it is this sector that has the greatest negative impact on visual apparatus.

In a world filled with numerous gadgets, people great amount time is spent in front of a computer monitor, not thinking about how tired the eyes are from light reflections. When using protective optics, the negative impact is minimized.

Those who have problems with refraction should consider buying anti-reflective products with diopters. They act as a protective barrier and correct existing deviations.

Indications for the use of anti-reflective lenses

By appearance the product is no different from ordinary eyepieces with diopters. However, if you look closely, you can see green or blue overflows on the surface. This is due to the fact that the lenses of anti-reflective products are coated with a unique coating that reflects glare - the main reason for the loss of visual acuity when working with a computer. Also, an antistatic layer is applied to the product, so that the lenses do not attract dust particles.

If a person has an ophthalmic problem, he is prescribed anti-reflective lenses with diopters. Of course, the product does not provide 100% protection against negative impact technique, so remember to take regular breaks from work so that your eyes can rest. It is advisable to be distracted from the monitor every hour, the duration of the rest is fifteen minutes.

Also, doctors advise anti-reflective glasses in the following cases:

• Regular work with gadgets for a long time;
• Tendency to dryness of the mucous membrane;
• Cutting and burning in the eyes;
• Increased lacrimation;
• Sensation of sand under the eyelids;
• Photophobia;
• Redness of the sclera;
• Chronic fatigue of the visual apparatus.

The difference between polarized and anti-reflective glasses

Even in specialized salons, these two concepts are often confused. To learn how to distinguish between them, you first need to decide on the definition of glare. These are spots that appear on a smooth or raised, glossy surface that reflects light. Thus, it turns out that any surface can glare (with sufficient illumination and at the right angle of inclination).

Light polarization is a more complex term. It manifests itself when the rays hit the plane at a certain angle, reflected and propagated in the vertical and horizontal direction. The more reflective a surface is, the more damaging glare is to the eyes. Vertical polarization conveys information about the shades of the object and its contrast, while horizontal polarization generates various noises (blind spots, reflections, etc.).

Glare appears regardless of the time of year. Rays can be reflected from the water surface, snow. In conditions of poor visibility (for example, in heavy fog), glare adversely affects visual acuity, since parameters and colors are distorted. The eyes get tired quickly, the person begins to experience discomfort.

Anti-reflective products are a completely different term, since such a surface should not give shine or create glare. Such optics include lenses with a unique coating that makes the visual system transparent. Such eyepieces are often also called enlightened.

Anti-reflective glasses reduce the amount of light reflection from the lenses, while increasing image contrast and visual acuity. If you look at a person in such products, you can easily see his eyes, and not see your own reflection in the glasses.

So let's sum it up. Anti-glare glasses let in more light without forming reflections. Polarized optics have less throughput, but also blocks a variety of interference well.

The principle of operation of anti-glare glasses for a computer

The PC monitor emits the entire "bouquet" of light fluxes, but most of all the blue and violet spectrum. These waves are responsible for excessive load visual apparatus, since they are part of UV radiation. Short rays scatter before reaching the retina of the eye. Thus, clearing the way for green and yellow long-wave streams. For this reason, the picture on the monitor often seems blurry. But red rays are considered useful, because they restore the metabolism in the tissues of the visual apparatus.

Anti-glare glasses block violet and blue light, preventing damage to the retina and lens. These eyepieces protect your eyes from electromagnetic radiation from the PC display, as well as from excessive brightness and glare.

Computer optics is designed to transmit orange and red streams, they have a beneficial effect on the visual apparatus. Also, the products block harmful short-wave impulses. As a result, image contrast and color reproduction are improved.

Anti-reflective lenses reduce drowsiness and increase efficiency by 30%, as the load on the eyes is reduced.

Working principle for drivers

The sun's rays, especially in the summer heat or snowy winter, can lead to an emergency on the road. Since they almost completely blind the person behind the wheel. Some car enthusiasts use regular tinted sunglasses, but they only slightly darken objects in the field of view, without protecting from glare.

For the first time on the market, anti-reflective glasses were released by Polaroid Corporation. Therefore, products this manufacturer considered a classic. Initially, the role of the polarizing layer was played by the thinnest plastic film, which was applied to the surface of the lens. The protective coating was located on top of the glass, which caused additional inconvenience, since it was often covered with scratches during transportation.

Modern technology allows you to hide the anti-reflective film inside the lens, which prevents its damage.

After watching the video, you will additional information about optics for drivers with a polarizing effect.

How to choose anti-reflective glasses

When choosing such products, first of all, you should decide for what purposes you plan to use it:

• Glasses with tinted lenses provide maximum protection from UV rays, scattering glare. They also significantly reduce the blinding of drivers by the headlights of oncoming cars. They make it possible to comfortably drive vehicles in the fog and reduce eye strain;
• Yellow lenses block UV, glare and reduce snow glare. They are recommended for use in low light conditions, in fog or on a blinding sunny day;
• Brown eyepieces also block harmful radiation, reduce headlight glare, relieve eye strain and allow you to drive in foggy conditions.

In any case, before buying, you should consult with an ophthalmologist who will help you choose the best option.

Glasses have become so firmly established in the life of a modern person that many people can no longer imagine life without them. Sunglasses, corrective glasses, protecting from wind and rain, or simply complementing the image of a business person - the benefits and importance of this stylish accessory are undeniable. At the same time, they also have disadvantages, one of the most serious is the appearance of glare on the lens on a sunny day. And if for office workers this remains a tedious, but generally safe nuisance, then for people in active professions such reflections can be serious danger. No wonder many people who are forced to stay under open sky, prefer anti-reflective glasses to regular sunglasses.

Anti-glare glasses: luxury or necessity?

On a clear day, any shiny object, mirror, polished metal, or simply the sun can be reflected in the lens of your glasses, causing blurring. The reason is insufficient absorption of light by the lens. It is to reduce this effect that a special anti-reflective coating is used.

The flash that appeared on the lenses of the glasses worsens the view and distracts attention, preventing a person from responding to a change in the situation at the right speed. Wet roads, mirrored shop windows, shiny surfaces of cars - all this increases the amount of glare and creates a danger to people both on the road and in everyday life.

Ordinary glasses also create an extremely unpleasant impression in photographs, because due to the reflection of the camera flash, in place of the eyes, often there is only a brilliant blurry spot.

It is especially important to purchase anti-reflective glasses in time for those people who experience vision problems. Reflections on the lenses make the eyes strain more, which causes overwork optic nerve and further loss of vision.

Anti-glare glasses for active people

For people whose life is connected with sports, driving or risky professions, they are dangerous enemies. A second of dazzle may be a minor annoyance for an office worker, but for a cyclist or tennis player, this very second can be decisive. That is why anti-glare glasses are so popular among fishermen, skiers, fans aquatic species sports.

Protection from unexpected flashes is especially important for car drivers, because the loss of visibility, even for a moment, is often the cause of terrible disasters. So, only in the Zurich canton of Switzerland, due to glare on the lenses, at least 5 accidents occur every month. Cars whose drivers use anti-reflective sunglasses, according to statistics, get into accidents much less often than the transport of their less prudent "colleagues".

Disadvantages of polarized glasses

Despite their many advantages, anti-glare glasses also have disadvantages that supporters of active life should be aware of.

Glasses with polarized lenses get dirty very quickly, they need to be cleaned much more often than ordinary ones. At the same time, they are not very scratch resistant, so it is recommended to wipe them with a special cloth - microfiber - using a cleaning spray.

Despite popular belief, when working on a computer, they are no better than regular tinted or corrective lenses. In such glasses it is not very convenient to view LCD screens, they will be practically useless even if it becomes necessary to consider something near the sun. However, they will still reduce the brightness, which will reduce eye strain by about 2 times.

It is also worth remembering that the anti-reflective coating of glasses is practically useless when the sun is at its zenith. The point here is the specifics of the refraction of rays in lenses.

Where to buy anti-reflective glasses

Glasses with anti-reflective coating become more and more popular every year, and there are many famous companies specializing in their production. Thus, the most popular brands in Russia are Polaroid, Lozza, Avanglion, Cucci, Persol, Ray Ban and many others. Acquire polarized glasses better in company stores or large department stores, since in small stalls and in the market there is too much risk of getting a fake instead of a quality item.

It is needed not only for people with but also much more for those who suffer from myopia. Ordinary tinted glasses bring more harm than good, because they cause the pupil to dilate and thus can cause retinal burns. Many optical shops can apply the required coating directly to corrective lenses for spectacles. The anti-reflective properties of such accessories are in no way inferior to products famous brands and at the same time make it easier for visually impaired people to walk down the street.

How to tell polarized glasses from regular glasses

Unfortunately, the growing popularity of glare-absorbing accessories has led to a large number fakes. In order not to purchase high price useless item, you should be very careful in the buying process.

Anti-glare glasses have some properties that conventional light-absorbing glasses cannot boast. They absorb part of the light rays and thus play the role of a filter. Therefore, the easiest way to exclude a fake is to look at a brightly lit object first through outside lenses, then - through the inner. On real polarized glasses, the reflection intensity should change.

If doubts remain, try to put one glass on top of the other and turn the top one by 90°. Glasses with anti-reflective coating will become opaque.

Anti-glare glasses are an essential attribute of modern life, filled with high speeds and numerous bright objects. For many people this thing is great helper both at work and at leisure. The main thing to remember when purchasing glasses with polarization is that this accessory has not only advantages, but also disadvantages.

Computer work is associated with constant eye strain. In 25% of cases, the frequent presence at the monitor develops chronic fatigue organs of vision, and increases the risk of developing various ophthalmic diseases requiring treatment.

Special anti-glare computer glasses can prevent unpleasant and pain, uncontrolled tearing, cramps and other similar symptoms.

Fashion accessory or necessity

If benefit regular glasses for vision correction is beyond doubt, the feasibility of anti-reflective optics may raise questions. What are anti-glare glasses for, what function do they perform, and how justified is their purchase?

Such an optic relieves symptoms negative impact on the eyes of electromagnetic radiation from a computer monitor and television screen. In particular, these are:

• eye fatigue symptoms general fatigue causing performance degradation.
• Sensation of dryness and grit in the eyes.
• Inadequate reaction to light (desire to close your eyes, turn away from the light, be in the dark);
• Erroneous perception of colors and shades (inability to distinguish and / or incorrect recognition of colors).
• Decreased sensitivity of eye receptors.

Anti-glare computer glasses are especially recommended for programmers, writers, graphic designers and other professions whose main activity requires many hours of sitting at the computer. It also effectively relieves eye strain in vehicle drivers.

How they work

Special computer optics acts as a kind of filter that prevents the effects of light and radiation on the eyes. Lenses are almost never colorless.

To cut off the blue-violet color spectrum and preserve the clarity and color reproduction of images without undue stress, they are covered with a protective layer of yellow, green or purple. Additionally, cutting-edge optics are coated with an anti-reflective layer, necessary to neutralize random glare.

At the same time, there are nuances of using such a “filter”:

1. Since getting used to it occurs gradually, at first it is recommended to wear anti-reflective glasses (AO) no more than 3 hours a day.
2. You can not use AO without the need: wearing outdoors can lead to absolute isolation of the eye from the sun, and provoke the “dry eye” syndrome, i.e. inability to lacrimation and vulnerability to light.

When buying protective anti-reflective optics with diopters, you need to choose a product 2 diopters weaker.

Varieties

In optics, you can purchase the following types of anti-glare glasses for a computer:

1. With monofocal lenses - designed for people with normal vision. This is a standard optic that allows you to cover a wide field of view.
2. With bifocal lenses, i.e. with dual focus. The optical zones in them are divided in such a way that one part is adapted for image perception at a close distance, the other - for focusing on the monitor. In this case, objects in the distance will not be clear.
3. With progressive lenses - divided into segments that do not have a visible border. They allow you to quickly "switch" vision from objects outside the monitor to the image on the computer without discomfort. 3 segments are adapted for viewing at a great distance ( top part), to perceive the "picture" on the monitor as a whole (middle wide part) and to focus at close range (small, lower segment).

Models with progressive lenses are considered the most practical, because. allow you to equally comfortably view objects and images at any distance.

How to choose

Anti-glare glasses to prevent fatigue, tearing, dryness and other painful sensations in the eye area cannot be selected solely on the basis of low cost, reviews or recommendations from friends.

Otherwise, you can harm the organs of vision or simply not achieve the goals pursued. When choosing an AO, they are guided by:

• Features of the visual receptors (this is important when choosing lenses, for example, glasses with monofocal lenses are not suitable for nearsightedness or farsightedness, since the “picture” can be blurred).
• Individually shaped eye sockets.
• The quality of the goods (when buying a cheap product, it is easy to “run into” a fake or a defective product; practicality and convenience should also take precedence over a fashionable solution for frames, etc.).

Anti-glare optics are bought via the Internet, through ads and in dubious stores. Such a product may do more harm than good, and not meet the expectations of the buyer.

Visual discomfort caused by regular use of a computer is called computer visual syndrome. It is diagnosed in 70% of people who work in front of a monitor for three or more hours a day. Anti-reflective glasses with regular use will help to avoid the development of myopia, hyperopia and astigmatism.

The effect of monitor radiation on the eyes

The reasons for this phenomenon lie in the peculiarities of the perception of the monitor by the human eye. When we read printed work, text and pictures are sharp, but the monitor includes a lot of flickering pixels. Therefore, the text on the monitor does not seem clear enough to the eye.

Focusing the eye is also difficult because the pixels near the center of the screen are brighter than those located at the edges. This dissonance causes fatigue visual system. In addition, vision is affected by the intensity of the glow, font features, the location of information blocks, colors, and even the position of the monitor.

In order to prevent deterioration of vision, you need to constantly follow the rules of working at a computer, monitor your posture and the location of the monitor (60-70 cm from the eyes). Every hour you need to take a break, do gymnastics for the eyes. To avoid drying out of the mucosa, you can use moisturizing drops. For a prescription, you need to contact a specialist.

Using even the most protected and modern monitor, a person still blinks 2-3 times less than usual. This leads to the drying of the cornea and the formation of microcracks. The presence of lesions in the mucosa causes discomfort and over time provokes a decrease in visual function.

Even with a slight deterioration in vision, you need to undergo an examination and find out the cause. If the deterioration is due to computer use, you can purchase special glasses that minimize harm.

The difference between polarized and anti-reflective glasses

It is noteworthy that even in optics salons, these types of optical systems are often confused. In order to understand these concepts, you need to know what glare is. And glare is a spot of light that is observed on a convex or flat glossy surface that reflects light. It turns out that any surface can create glare (at a certain angle, as well as with proper lighting), even the lenses of glasses.

The polarization of light is a more complex concept. It occurs when light hits a surface at a certain angle, is reflected and propagates predominantly horizontally and vertically. Vertical polarization of light conveys information about colors, contrast, and so on to a person, while horizontal polarization creates noise, glare, interference, and blind spots. And the higher the ability of the surface to reflect light, the stronger the glare will affect vision.

Glare occurs at any time of the year. This occurs when light is reflected from snow, water, and even in foggy conditions. In conditions of poor visibility, glare reduces visual acuity by distorting colors, shapes, and contrast. All this provokes eye fatigue and corresponding discomfort.

It is noteworthy that the reduction in light intensity through the use of sunglasses does not reduce glare. To reduce the negative effect of glare from horizontal surfaces, only polarized lenses that have a polaroid coating. The principle of operation of glasses is hidden in a transparent polarizing film that blocks reflected rays.

Polarized glasses eliminate glare and allow you to see the world clearly without damaging the eyes. These glasses are recommended when driving vehicles as bright reflections can dazzle.

Anti-glare glasses are a different concept, since an anti-reflective surface means one that has almost no shine and no glare. It is correct to call anti-reflective those lenses that have a special coating that makes the optical system more transparent. Such glasses are also called enlightened or anti-reflex.

Anti-reflective lenses are designed to transmit light and reduce the reflection of light directly off the glasses. Thus, image contrast and visual acuity are increased. If you look at a person who wears such glasses, you can see his eyes, and not a reflection in the glasses. It turns out that anti-reflective glasses let in more light, without giving reflections, and polarized glasses block reflections, letting in less light.

The principle of operation of anti-glare glasses for a computer

The computer screen emits the entire spectrum of light rays, but mainly violet and blue waves overload vision. They are part ultraviolet radiation. It is also noteworthy that short-wavelength rays are refracted and scattered halfway to the retina, making way for green and yellow long-wavelength rays, and therefore often the image on the screen seems blurry. Interestingly, red rays are very useful, they restore metabolic processes in the eye tissue.

The benefit of anti-reflective computer glasses is that they block violet and blue rays, protecting the retina and lens from ultraviolet radiation. Similar optical systems protect your eyes from electromagnetic radiation from the monitor, as well as glare and excessive brightness.

Computer glasses are designed to let through the red and orange parts of the spectrum, which have a beneficial effect on the organs of vision. They also block shortwave - harmful - rays. Thus, contrast and color perception are increased.

Anti-glare glasses reduce drowsiness and increase efficiency by 30% (by reducing eye strain).

Indications for the use of anti-reflective lenses

In appearance, computer glasses do not differ from conventional optical systems with diopters. However, upon closer inspection, you can see green, blue and purple overflows on the surface of the lenses. This is due to the fact that a filter coating is applied to the glasses of computer glasses, which reflects glare - the cause of reduced vision when working in front of a monitor. Also, computer glasses have an antistatic layer that does not allow the glass to be magnetized.

If the patient has reduced vision, doctors usually prescribe anti-reflective glasses with diopters. It must be remembered that such glasses do not completely protect the eyes from negative influences, so you need to periodically take breaks from working at the computer. To minimize harm from the monitor, it is enough to give your eyes a rest for fifteen minutes every hour. For these purposes, you can install a special program on your computer that will remind you of the need to organize a break.

Computer glasses are shown to those people who spend more than three hours a day in front of the monitor. Similar optical systems are allowed for both adults and children.

Indications for the use of anti-reflective glasses:

• regular and long-term use of equipment with screens (phones, tablets, computers, etc.);
• tendency to dry out mucous;
• feeling of pain or burning;
• tearing;
• photophobia;
• redness;
• chronic eye strain.

Patients note that when wearing anti-reflective glasses, their performance increases due to the fact that eye fatigue is reduced. With use, dryness and burning disappear, as well as pain during overvoltage. It also reduces the frequency of headaches and dizziness.

How to choose anti-glare glasses for work and life

You should always remember that even with minor health problems, it is always better to consult a doctor. Despite the simplicity and safety of anti-reflective glasses, it will be better if they are prescribed by an optometrist. This is due to the fact that during the examination, the doctor can identify a serious deviation and prescribe treatment in time. Pain and redness often accompany inflammation of the eyes.

When choosing anti-reflective glasses, you need to consider the following factors:

1. Frame characteristics. For your own comfort, you need to choose a frame that will fit the shape of the face and the taste of the patient. You also need to make sure that the frame does not put pressure on the bridge of the nose or ears.
2. Image quality. Glasses should not distort the picture, increase or decrease objects, narrow the horizons.

When the patient does not have vision problems, the doctor can prescribe ordinary "pacifiers", the glasses of which will be coated with a protective anti-reflective layer. Anti-reflective lenses are made of plastic and glass. Plastic ones get scratched quite quickly, but they are recommended for children, because they do not break into fragments under pressure and do not injure the eyes.

Types of lenses for anti-reflective glasses:

1. Monofocal. Thanks to such lenses, a normal perception of objects without size distortion is ensured. Such optical systems are suitable for people with normal vision. Their task is to reduce eye fatigue, they prevent the deterioration of vision and even a violation of posture. Thanks to monofocal lenses, headaches and discomfort in the neck disappear. These glasses are most often prescribed to young and old people.
2. Bifocal. These lenses have two optical zones: the upper one is designed for studying objects on the monitor, and the lower one helps to see objects at close range.
3. (progressive). These lenses have three optical zones for different mode work (computer, near, far). These glasses provide the most comfortable use of modern technology.

When choosing glasses, be sure to study the documentation for the product. So you can save yourself from buying a fake, which is quite capable of being harmful to the eyes. The goods of German, Japanese and Swiss manufacturers are recognized as the highest quality. Chinese lenses are less effective and durable, but are sold at an affordable price.

It must be remembered that even the most expensive monitor does not provide eye protection. Therefore, anti-glare glasses will be indispensable for anyone who spends a lot of time in front of a computer or TV. You can always choose a frame that will make glasses not only useful, but also stylish.

Features of anti-glare glasses for drivers

If we talk about drivers, anti-glare glasses help them recover their vision faster after being blinded by the headlights of oncoming cars. However, such lenses (with the addition of diopters) are recommended only for drivers with reduced vision, since in normal vision, any lenses reduce light transmission. Drivers will benefit from polarized lenses that protect against glare, but should not be used at night or in bad weather.

Anti-headlight glasses will be much more effective when driving. They include yellow or yellow-orange lenses that delay Blue colour. These glasses can be used at night and in bad weather, as they increase the contrast of the image.

Given all of the above, we can conclude that all computer users need anti-glare glasses. They will not only save you from discomfort and eye fatigue, but also avoid serious violations vision.
