Chameleon glasses are in demand among people who need eye health prevention or purchase them for medical reasons. But fashion-conscious people often buy these accessories for everyday protection of the retina from ultraviolet radiation. The uniqueness of chameleon sunglasses lies in the glasses containing a photochromic substance (silver or copper hologenide), due to which, when exposed to sunlight, the degree of darkening of the lenses changes. Indoors, chameleons remain light-colored.

Chameleon glasses: purpose and types

In chameleon sunglasses, along with UV protection, there is a vision correction function, so they are also produced with different diopters. Photochromic lenses for vision correction or without it can be mineral (glass) and polymer (plastic). Doctors recommend wearing glasses with mineral glasses to patients with eye diseases. They are also suitable for daily UV protection, but glass lenses can break with the slightest impact, even after anti-shock treatment.

Chameleons with polymer lenses are more suitable for everyday UV protection because the plastic is durable and lightweight. Moreover, new technologies are constantly improving polymer coatings - even more durable materials are created every year. If mineral lenses are not tinted, then plastic lenses can be chosen with any degree of coating. For more information about photochromic lenses, watch the video presentation by M. Blagovestny, head of BBGR (France):

For vision with diopters

Most chameleon glasses are commercially available - these are products with conventional photochromic lenses intended for normal vision. For people with low vision, farsightedness, myopia, and age-related eye diseases, models with diopters are recommended, the purpose of which is aimed at neutralizing all of the above diseases with the help of collecting or diffusing glasses.

When choosing diopters, each eye is examined separately, first weak and then strong convex glasses are applied to them in turn, with the help of which the patient reads the lines on a special table. The strongest convex glass shows the degree of farsightedness or nearsightedness of a person. High-quality sun protection chameleons with diopters can also be used in extreme sports, such as skydiving, skiing, cycling and motorcycling. These models are made of very durable material to protect your eyes from particulate matter.

When buying chameleons with diopters, you should consult an ophthalmologist for the correct selection of lenses. The specialist will determine on an individual basis the degree of darkening, the required type and color of lenses. When choosing the shade and shape of the frame, a person can rely on his own taste. To eliminate discomfort, it is better for people with low vision to choose flat-shaped models, when the lenses are in front of the eyes in the same plane.

Sunscreens without diopters

Chameleons without diopters make it possible to feel comfortable both indoors and outdoors. In winter they protect from bright snow, in the spring-summer period they make it possible not to squint on hot days when the sun's rays penetrate everywhere. The highest quality sun protection chameleons are considered to be models from Ray-Ban and Polaroid. Their glasses are equipped with lenses with a high-quality polarizing filter, which 100% protects the eyes from ultraviolet radiation, unlike low-quality Chinese counterfeits.

Special glasses for drivers

There are chameleon sun protection models designed specifically for drivers. Anti-headlight lenses react to weather conditions, changing their color at different levels of illumination. The anti-glare properties of these glasses allow much more light to pass through, so the driver's eyes adapt faster after being blinded by the headlights of oncoming cars. Chameleons designed for driving cars are great help in poor visibility conditions, greatly improving the quality of vision.

Beautiful male and female models with photos

Fashionable sun chameleons are divided into two types: women's and men's. Glasses designed for women have a more elegant design, small size, thin arms and frames with various decorative elements. Men's models are distinguished by a small number of different shapes, they are massive, and the inlay on the frame (if any) is usually discreet. Sunglasses from Polaroid or Ray-Ban, both men's and women's, have a classic design, so they ideally complement the image of a business person, matching the color scheme with different accessories.

Lens darkening levels

The degree of darkening of sun chameleons varies, so they are divided into three types:

1. Low dimming 10-55%. The color of the glasses in these glasses is brown, and this type is intended for daily wear by people with normal vision.
2. Average dimming 15-65%. Glass is usually gray in color. These models are designed for drivers.
3. Strong darkening 30-85%. The glass is green. These models are designed for people with a high degree of photosensitivity.

How to choose chameleon sunglasses

High-quality chameleon sun protection optics differ from cheap analogues in the following parameters that you need to pay attention to when choosing:

• A real lens has a dark edge, but if its color is light, then it is only sputtering and not photochromic glass.
• High-quality glasses retain natural colors, while counterfeit glasses will distort them.
• The “native” coating will lie perfectly evenly. If it has an uneven application, then you have stumbled upon a fake.

Do you need chameleons: reviews

Daria, 30 years old

First, I bought Ray-Ban chameleons as a stylish accessory so that I could sit at the computer with a businesslike look at work. I really liked the look of the model, and the colors are very natural. Then I started going outside in them and using them as sun protection - they become darker in the sun. Now I never part with these glasses and haven’t bought others for several years.

Nikolay, 43 years old

I work as a truck driver, and a colleague advised me to buy chameleons for flights. At first I was skeptical, but then I purchased it and was very pleased. In addition to solar radiation during the day, glasses protect my eyes and me at night from the headlights of oncoming cars. I don’t take them off day or night while I’m driving.

Anastasia, 27 years old

I received chameleons as a birthday present. At first I didn’t understand why they were white indoors, because sun-protective models should be darkened. But when the glasses changed color in the sun, I really liked the result. I wear them in winter and summer with any style of clothing, since the classic frame gives this opportunity.

How much does it cost to buy such glasses - approximate prices

Chameleon glasses in Russia, as well as in other countries, are sold at different prices. If you prefer a quality product, then you should pay attention to the models of the Polaroid company, the cost of which will range from 2000 to 5000 rubles, depending on the store’s policy. You can easily find Ray-Ban glasses at prices ranging from 1,500 to 3,000 rubles. Cheap Chinese analogues can be found in online stores and in markets of any city at prices ranging from 500 to 1000 rubles, depending on the model.

Photochromic glasses help people with visual impairments, protect against ultraviolet radiation and have many advantages over other optical devices. How do they work and are there any disadvantages to using them? Let's figure it out.

Photochromic glasses change color as the light changes.

How do photochromic glasses work?

What are photochromic glasses and what are they for? This is a device in which the lenses simultaneously correct visual acuity and are able to regulate the level of darkness. The impetus for action is the degree of illumination and the angle of sunlight hitting their surface. Chameleons are the second name for such glasses.

If a person is indoors, chameleons do not give themselves away in any way by appearance. Transformations occur when going outside, when the glass begins to quickly darken and protects from the sun no worse than special solar glasses.

When entering a room, the lenses adapt to moderate lighting in a matter of seconds and become brighter

Such glasses are designed for the convenience of people with poor vision. This is especially true in the summer, when the eyes of even a healthy person lose visual acuity in the bright sun and quickly get tired.

Lenses for chameleons contain pigment molecules of a sensitive substance that actively react to ultraviolet radiation. They are activated when it appears and return to their initial position in its absence.

The intensity of glass tinting is higher, the brighter it is outside and the more aggressive the solar radiation.

In other words, glasses with photochromic lenses protect your eyes on a clear day by transmitting much less visible light rays. The color of such lenses can be brown or gray.

Photochromic glasses: pros and cons

Glasses with photochromic lenses cannot provide 100% protection from sunlight for a long time. This is the task of special sun protection models. Therefore, when going on vacation, it is safer to take both pairs with you.

It happens that in an office environment and when working at a computer, the glass often changes color, and this provokes rapid blinking when the lighting changes, the eyes quickly get tired, redness and headaches are observed.

Most people have difficulty seeing, and some experience discomfort in bright and sunny weather. In such a situation, to protect the eyes, they need lenses or glasses.

One of the modern devices can be called chameleon glasses. They are worn in any light, put on outside and not taken off indoors.

Chameleon glasses have photochromic lenses, which are lenses that can change the tone and degree of darkness depending on the amount of sunlight they receive. The lenses are brightened while the person is in the building, since the amount of ultraviolet rays received is minimized. When going outside, the glass darkens, trying to protect the visual organ from exposure to large amounts of light.

Chameleon glasses have a main feature, which is the presence and absence of diopters. That is, they can also be worn by people with poor eyesight.

The degree of darkness of chameleon glasses

The frame of the accessories can be made of any material: plastic or metal. It is believed that metal products are much lighter and more convenient to use. But the lenses themselves should be made of glass, since this is the material that helps create a real photochromic plane.

The glasses are divided according to the degree of darkness.

1. For weak form. Absorb up to fifty percent of light. They have brown lenses. Often these models are worn by the female half of the population.
2. For medium shape. They absorb light from fifteen to sixty percent of light. Such models are perfect for walking on the street and for those people who drive a car. They have gray glass.
3. For enhanced form. Absorb up to eighty percent of light rays. The lenses are green in color. These models are mainly used by patients suffering from conjunctivitis, increased sensitivity to light, pain and dryness.

Experts say that it is better to choose chameleon glasses with a medium degree of darkness. After all, they do an excellent job of correcting vision and protecting it, while the products have a long service life and are quite durable.

Chameleon glasses for drivers

Chameleon glasses can also be used by drivers who are constantly behind the wheel. For their manufacture, photochromic lenses are used, which have the property of changing color depending on the light level. For drivers, this accessory will be a godsend, because the visual organ will always be protected without any damage.

Modern glasses can protect your eyes as much as possible inside the car. Glass contains substances that regulate not only ultraviolet radiation, but also absorb the blue light spectrum contained in the sun's rays. The lenses can darken up to eighty percent, which will allow you to control the situation on the road section even in bright, blinding light.

Such lenses are a great find for drivers who have problems with visual acuity. After all, simple products with diopters do not protect against glare and bright sun. Chameleon glasses are a replacement for several accessories at once.

Just a few years ago, glasses were not in such demand among people because the quality of the lenses was poor. But more recently, lenses made of high-quality material with diopters began to arrive in stores.

Popular chameleon glasses models for men and women

Chameleon sunglasses can be divided into two types: men's and women's. Products for the female half of the population have a more elegant appearance, while being small in size, with thinner arms and frames with different decorative elements. There are not many varieties of men's glasses. They differ only in their massiveness and variety of frame shapes.

Instructions for choosing the right chameleon glasses

To buy glasses, you need to be able to distinguish high-quality work from inexpensive analogues. To do this, you should follow several recommendations.

1. This lens has a dark colored edge. If it is light, it means that the glasses are just coated and they are not photochromic.
2. If you look through high-quality glass, they will not distort color perception. If you have a fake in front of you, the naturalness of the colors will be disrupted.
3. A good quality spray will lie perfectly flat. If it is poorly applied, then such glasses are fake.
4. If the buyer has vision problems, then glasses must be purchased with diopters. To do this, you should contact an ophthalmologist for a vision test. The doctor will write out a prescription, according to which the optician will make custom-made glasses.
5. Every two years, lenses must be replaced, as the coating loses its function and gradually wears off.
6. You need to care for them in the same way as regular accessories. Wipe daily with a special cloth, store in a case and place on the surface with the lenses facing up.

Price for chameleon glasses in stores

Cost of sun protection accessories.
The price of chameleon glasses depends on several parameters.

• What material are the lenses and frames made of?
• Availability of decor.
• Availability of diopters.
• Manufacturer's fame.
• Store markup.

On average, the price for high-quality models ranges from one to two thousand rubles. If we talk about accessories from well-known companies, their prices range from two to five thousand rubles. But there are also fakes on sale that cost much less. Good glasses are absolutely safe for the consumer's eye health. But the fake not only does not affect the image quality, but also harms the eyes, not retaining ultraviolet and anti-glare rays.

Notes on choosing glasses

It is worth noting the fact that modern models can be selected to suit any clothing style and image. Naturally, chameleon glasses should be selected taking into account several circumstances - the season, face shape and type of clothing. For example, for people with a round and wide cheekbone face, models in the shape of a cat's eye and a fox with lenses that are tapered at the top are perfect. Narrow-faced people need to visually expand their face, so they should choose glasses with a small square shape. In addition to all this, the frames of men's accessories should be much more massive than those of the women's half.

Elegant glasses will go well with evening wear, especially with classic clothes. In the summer, you should pay attention to lightweight glasses that have light-colored frames. If the buyer prefers active winter recreation, then you need to select products with a large view and anti-reflective coating.

You can also match glasses to the color of accessories or clothing, or the shade of your eyes or hair. Today, glasses are not just a method of vision correction, but also a stylish element in the image.

Photochromic glasses for older generation glasses had certain problems: the darkening rate depended on the light level and ambient temperature. In the cold the lenses darkened faster, and in the heat the changes came more slowly. Modern technology for the production of photochromic glasses has been brought to perfection and there are no such problems. But, nevertheless, there are also disadvantages.

Operating principle

Glasses with photochromic lenses can be intended for household use or for sports, driving, and made of glass or polymers. In any case, all glasses are coated with a photochromic substance. Photochromes change their spatial structure under the influence of ultraviolet radiation. This makes the lenses darker. In the absence of sunlight, the structure changes in the opposite direction.

Indications

Who is suitable for photochromic lenses? They will be useful both for people with visual impairments and for those who work outdoors, drivers, athletes, cyclists and travelers.

But glasses with photochrome also have medical indications for wearing them. They are recommended to be worn by people with, if there is a risk of developing. Such lenses significantly reduce the development and progression of pathology.

Varieties

Photochromic glasses with diopters are not just a fashion accessory. They will help to simultaneously correct vision and protect the eye from the negative effects of ultraviolet rays. In addition to corrective photochromic sunglasses, there are other types of them:

• bicycle;
• sports;
• for drivers.

In addition, there are photochromic polarized glasses with anti-glare effect. They are designed to protect your eyes from the glare of water, asphalt and snow.

Bicycle

Both amateurs and athletes need eye protection. Photochromic glasses will help cope with this. They will eliminate factors such as:

• ultra-violet rays;
• blinding sun;
• dust, dirt, insects, debris that may get into your eyes while riding.

If the lenses are polarized, they will also eliminate the glare of water or snow.

You need to choose the right cycling glasses. They should fit snugly to the face both in front and on the sides. In addition, it is better to choose polymer rather than glass lenses, since in case of a fall you will be able to avoid injury to the eye.

Sports

Sports photochromic glasses are necessary for those who run, ski, and snowboard. Such an accessory will not only protect your eyesight, but will also make it possible not to be distracted by extraneous factors, which is important for achieving results.

The photochromic lens itself sets the percentage of darkening required in a given weather, whether it is a cloudy or sunny day. This makes it possible to train in any weather conditions.

Chameleon glasses will also be useful for tourists. They reduce eye strain, allowing you to walk the path comfortably. This is also important for the safety of the tourist, especially when overcoming a difficult path in mountainous or forest areas and on water.

For drivers

According to statistics, a third of accidents occur when the driver is blinded by the light of an oncoming car or glare from a wet road. Photochromic glasses with polarized lenses allow you to avoid these factors.

Previously, photochromic lenses did not change their color when a person was in a car: ultraviolet rays simply did not penetrate the glass. Modern polarized glasses with photochrome for drivers capture blue rays, which have a short wavelength. Therefore, they will perform their function even behind the car window. These glasses not only correct vision, but also help avoid glare and protect the retina.

Advantages and disadvantages

Photochromic lenses have both advantages and disadvantages. The positive aspects of lenses with photochrome include the following:

• replaces 2 pairs of glasses;
• ease of use;
• versatility and ease of use;
• good visual effect.

But there are also some disadvantages:

• Photochromic lenses are not able to protect 100% from ultraviolet light for a long time. Therefore, when staying in the sun for a long time, it is necessary to take additional sunglasses;
• In some cases, lenses may change color when working on a computer. In this case, the person blinks often, and the eyes get tired faster, turn red, and headaches occur more often.

Selection rules

Which photochromic lenses are best and how to make the right choice? In order not to make a mistake, first of all you need to learn how to distinguish high-quality glasses from a cheaper option.

A good photochromic lens has a dark edge. If the fin is light, then the glasses are simply sprayed, but the glasses will not be photochromic. If a high-quality composition was used to make glass, then it lies evenly on the surface of the lenses. A good accessory does not distort the color when viewed through the lenses. If after putting on the glasses the colors become unnatural, then it is a fake.

Every 2 years, lenses must be replaced as the photochromic layer wears off. Every day you should wipe the glasses with a cloth and put the glasses in the case.

Photochromic lenses are an excellent solution for people with visual impairments. They not only have a corrective property, but also prevent the development of serious diseases. This accessory is also suitable for people leading an active lifestyle. Photochromic glasses are a universal solution to several problems.
