Rating of photochromic lenses in 2021 buy. TOP - 10 best.
Rating 2020
In the age of computer technology, it is becoming common to meet a person with poor vision. In order to improve it, you can use different methods - have surgery, wear lenses or glasses. Despite the fact that contact lenses do not spoil the appearance of the face, their use creates some inconvenience for a person - after a while the eyes begin to become inflamed and irritated, and turn red. And putting them on is inconvenient - all manipulations must be carried out with clean hands and in the presence of a mirror, which is not always possible to ensure.
Many people prefer to wear classic glasses. Like other medical devices, they are also constantly being improved, and one of these improvements has been the use of photochromic optics. This technology has been known since 1964, and is being improved more and more every year. Chameleon glasses have the ability to change the amount of light transmission depending on the light level. Outwardly, it looks like this: when bright light hits them, they darken and reduce the number of rays that penetrate the eyes, and when going into a dark room, transparency increases.
In this article we will tell you how to choose glasses with photochromic optics, what to look for so as not to make mistakes when choosing, and also make a Rating of the best Ratings of high-quality and popular optics models from the best manufacturers.
How to choose the right lenses for glasses
Before you go to the optician, you need to visit an ophthalmologist and undergo a full examination, especially if you are choosing this accessory for the first time. An ophthalmologist will examine refraction, measure the curvature of the cornea, pupillary reactions, intraocular pressure, examine the fundus and then make an accurate diagnosis. You should not save time on going to the doctor, because even the slightest deviation in the prescription will doom you to the wrong purchase and lead to unnecessary financial expenses.
After the doctor has written a prescription, you can go to the optician. The frame can be metal or plastic. The first ones are the most highly durable and less susceptible to deformation, but they make the glasses heavier and can cause allergies. Plastic options are not as massive, but are inferior in strength. The ideal option is metal temples and plastic temples. It would be good if there were silicone pads on the nose pads.
What determines the price of chameleons?
It is very difficult to navigate the wide range of the market, especially if you are choosing an accessory for the first time. Price plays a huge role here, it is important not to fall into the hands of scammers.
Many increase the cost, at their own discretion, attributing supernatural properties to ordinary chameleons. If you focus on price, you need to remember a few tips:
- The final cost of the product will depend on the quality of the frames and lenses. Analyze the product offered, visit the websites of well-known manufacturers. You should not trust the seller; he often offers cheap goods at a high cost.
- Many buyers want to decorate the frame using various decors. Of course, such glasses will be a little more expensive than their regular counterparts.
- For vision correction, prescription lenses cost significantly more than glasses for style.
- The brand matters; well-known companies, as a rule, increase the price due to their fame. Of course, trust in the manufacturer makes us overpay. No need to look at the brand; stick to the rules of choosing by quality, not by price.
- Store markups are the scourge of modern trade. To increase profits, unscrupulous sellers purchase cheap goods and sell them at an inflated price in order to profit from the consumer. You shouldn't buy glasses at the first store you come across.
- If you analyze the entire market and follow the advice of experts, you can purchase high-quality chameleons within two thousand.
Refractive index
The choice of the base of glasses is carried out according to several indicators at once, one of the most important is the refractive index. It determines the ability of glasses to transmit sunlight. The higher this indicator, the thinner, lighter and more expensive the lenses will be. High index elements reflect 50% more light than their low index counterparts. They provide maximum efficiency and often feature an aspherical design.
When focusing on the refractive index, it is worth taking into account individual characteristics, doctor’s advice and frame material. According to the refractive index and modification of the lenses, they are distinguished:
Coefficient | Purpose |
1,49-1,5 | low index suitable for small dioptres |
1,5-1,56 | Ideal for any frame, reliably protects the eye from ultraviolet rays |
1,61-1,67 | much stronger and thinner than standard glasses, best suited for rimless frames |
1,74 | ultra-thin are designed for vision correction with high diopter, used in rim frames. |
The only disadvantage of highly indexed glasses is the low dyspepsia coefficient; such lenses cause severe color distortions. Light passing through the polymer is decomposed into several components, which can cause iridescent distortions at the edges, which in medicine are called chromatic aberration. The lower the dyspepsia factor, the more colored spots you will see around objects.
Disadvantages of chameleon glasses
It’s worth noting right away that all the shortcomings that will be listed below apply only to products that are manufactured using outdated technologies. Currently, most of them are irrelevant; the only disadvantage of such accessories is the high price per unit. Flaws:
- Long time to change the lighting mode.
- Difficulties when working in conditions of elevated ambient temperatures.
- Uneven dimming in different areas, this is especially true for cheap products.
- Inaccessible to wear while driving, since car glass does not transmit ultraviolet rays.
- A small number of color options - most often, models with green and brown shades are found on sale.
When choosing photochromic optics, consultation with an ophthalmologist is required.
Optical zone selection
The next type of classification is the optical zone. It characterizes how many tricks the glasses have. There are three main types:
- Afocal. They do not have an optical zone and are prescribed by doctors only if there is no need to correct vision. Afocal options are installed in sunglasses, computer glasses, fashion glasses or office glasses.
- Single vision. They can provide vision correction either near or far. The entire surface of such glass has the same number of diopters. Single vision glasses are prescribed to elderly patients to correct poor accommodation.
- Multifocal. The surface of such glass is divided into zones with different diopters. Multifocal elements help you focus your gaze at different distances.
Lens shape
Modern production technologies make it possible to develop lenses not only with a high refractive index and different optical zones, but also of various geometric shapes. The shape affects the thickness, lightness of the frame, the aesthetic appearance of a person, and the brightness of peripheral vision. Based on their shape, lenses are divided into:
- stigmatic or spherical;
- astigmatic or aspherical;
- bifocal or biaspherical;
- progressive or trifocal.
Stigmatic form
This is one of the most popular designs - convex. The spherical shape is inexpensive and suitable for almost any occasion. The surface of such glasses is marked point by point with identical diopters and has an equal radius of curvature. The spherical elements provide high-quality vision only in the central part, the curved side gives a distorted view to the sides. There are two types of stigmatic form:
- biconvex – for correction of farsightedness;
- biconcave – to correct myopia.
Astigmatic
These are lenses in which one or two surfaces are non-spherical. Thanks to this geometric feature, they have minimal optical distortion of objects. When wearing aspherically shaped accessories, a distortion in the size of the eyes may occur. Disadvantages include multiple reflections that appear on the surface of the glass, which is why they are often produced with a special anti-reflective coating. Astigmatic type is prescribed to people with a high degree of myopia or farsightedness.
Bifocal lenses
They have two spherical surfaces on the inside and on the outside. The specific construction provides the widest possible overview and clarity of the image of objects. In addition, the bifocal shape is thinner compared to other types. Ophthalmologists recommend wearing it with high diopters or astigmatism, when the patient needs the lightest possible design.
Progressive
If earlier people bought several types of glasses at once (some for vision, others for watching TV or reading), today scientists suggest using progressive lenses. At the top there is an area for distance vision, and at the bottom for viewing nearby objects. They do not blur the contours of objects when moving from one type of vision to another. The only disadvantage is that it takes a long time to get used to. They are not recommended for patients who have cataracts, strabismus, or a large difference in diopters between the right and left eyes.
Photochrome lenses for drivers
Another category of optics for people who drive for a long time. It is very important for drivers to be able to see the road and accompanying vehicles in any weather and time of day.
Those who experience vision problems used to have to resort to a trick and use 2 pairs of glasses at once to protect their vision from sunlight and headlights from oncoming cars.
This is not only inconvenient, but also dangerous from the point of view of accidents. With the advent of photochrome on the market, everything has changed; now you don’t need to use various tricks, you can simply purchase photochromic lenses and enjoy comfort on the road.
Types of glasses lenses
If previously only glass was used for vision correction, now there is a wide selection of other materials that are safe for humans, and the technology for making glasses is improving every time. Glass or mineral elements still remain popular due to their low cost, but they are being replaced by polymer elements that are lighter but have a higher price.
Glass (mineral)
The most popular type of lenses. They are made from special grades of mineral glass, which are characterized by high oxygen permeability. The main advantages of mineral glasses:
- Durability. The glasses can be used for a long time, while the surface remains unclouded.
- High optical characteristics and increased resistance to scratches on the surface.
- The best option for people with a high minus. Their refractive index is higher than that of plastic options.
- High throughput, thanks to which glass elements are used to create anti-glare, polarized and sunglasses.
Many advantages do not hide the significant disadvantages of glass lenses:
- They have low shockproof properties, so they are not recommended for wearing by children and athletes. To preserve the integrity of the glasses, it is recommended to store and transport such glasses in a special durable case.
- They can cause discomfort when worn for a long time, leaving marks from the frame on the bridge of the nose, causing headaches and dizziness.
- Lenses with photochromic coating have low light transmittance characteristics.
Polymer
Modern safe plastic has become an excellent alternative to glass for vision correction and quickly gained popularity among consumers. The main advantages of polymer elements:
- Short adaptation period. Compared to glass ones, they are much lighter, so they do not cause fatigue or discomfort when worn for a long time.
- Safety, low injury rate. The plastic is unbreakable, so even with a strong impact you don’t have to worry about a splinter getting into your eye.
- Plastic is easy to process, allowing manufacturers to create different designs.
- Polymer elements retain optical properties even under extreme conditions, do not fog up, and help you see clearly in the rain.
When choosing polymers, it is worth knowing that depending on the color palette, the perception of the surrounding world and even your mood may be slightly distorted. For these reasons, ophthalmologists recommend choosing clear or discreet glasses that minimize color distortion. Other disadvantages of polymers include:
- They scratch, so they should only be carried in a case.
- Not suitable for people with high handicap.
- High cost of glasses lenses compared to glass elements.
Depending on which organic material was used for production, polymers are divided into three subtypes:
- Thermosets are compounds of liquid monomer molecules, which are obtained by polymerization of ultraviolet light. The most common material is CR-39. Its properties are close to crown-type minerals, but it is 40% lighter.
- Thermoplastics are polymers produced by thermal interaction or by granule casting. The most famous thermoplastic is polycarbonate. It is highly resistant to injury.
- Quasi-thermosets are a combination of several types of plastic. They have high optical properties, are resistant to damage, and do not distort space.
Benefits of chameleon glasses
- There is no need to buy two accessories - they can replace both eyeglasses and sunglasses.
- Adaptability – depending on weather conditions, the degree of transparency of the optics changes, making the eyes comfortable in any weather, while protection from ultraviolet radiation is always at a decent level.
- A large number of design types and varied designs allow you to choose an accessory depending on the buyer’s preferences.
- They can be used not only by healthy people, but also by those who have various visual impairments.
Types of coating
When choosing glasses, you should pay special attention to the presence of special protective coatings. It can be anti-grease, with a mirror coating, antistatic or with a dirt-repellent effect. Popular types of spraying:
- reflective - prevents damage to the eyes from bright flashes of headlights, preferably for motorists;
- hydrophobic – will protect the surface from water accumulation;
- brightening – will reduce eye strain, preferable for those who sit in front of a computer monitor for a long time;
- mirror – provides maximum protection from UV rays, used to create sunglasses.
Water repellent
It is important for every consumer that the optical surfaces of glasses remain clean and transmit maximum light even in extreme weather conditions. To meet such needs, manufacturers apply a special hydrophobic coating. A thin silicone film completely covers all irregularities, allowing water droplets to easily roll off the surface. Such glasses are easier to get rid of dirt and dust; they almost never fog up when moving from a warm room to a cold one.
Anti-glare
This spray helps protect your eyes and help you recover faster from being blinded by bright lights in poor visibility conditions. Anti-reflective coatings are used to create glasses for motorists and are very popular. The special layer relieves tension from the eyes, soothes, and refracts light well in the dark. Anti-reflective coatings are used not only to create prescription glasses, but also for accessories not intended for vision correction.

Strengthening
This coating helps maintain the integrity of the surface upon impact and prevents scratches that distort vision. Hardening coating is present only on lenses made of organic polymers; it is rarely used on glass. For different materials, manufacturers select hardening varnishes with the appropriate light refractive index.
Enlightening
A coating that is used to increase the clarity of a lens and reduce the reflection of light from its surface. The disadvantage of anti-reflective film is that it reduces impact resistance. If the glass is subjected to heavy loads, falls or impacts, the anti-reflective elements may crack or peel. For these reasons, wearing glasses with this coating is recommended only when working at a computer.
Anti-reflex
A coating that helps eliminate glare from the surface of glass. In addition, their presence interferes with eye contact between interlocutors. To eliminate the defect, manufacturers often apply an anti-reflex film to the surface of glass or plastic. It improves picture quality, the passage of light and oxygen, eliminates glare, and does not interfere with the view. In addition, the anti-reflex coating improves visual acuity.
Mirror coating
A coating that has a high level of ultraviolet ray filtration. Mirror coating is used for the production of sun protection accessories, both with and without diopters. This type of coating is applied to obtain a cosmetic effect and protect the eyes; it does not have any effect on the sharpness, quality and correction of vision. Mirror coating in different colors gives the accessories a stylish look and unusual design.
Production methods
There are two popular options sold in stores - glass or plastic. Their production method is different. For example, to create a glass model, a special coating is used, consisting of molecules with a photochromic structure. It is added only when it is in a liquid state.
The production of plastic lenses can be carried out in three ways. However, each of them is different from the other:
- Adding photochrome to plastic and subsequent hardening is the most reliable and durable method;
- Impregnation of plastic lenses with photochrome;
- Apply a thin layer to the front side. This method is convenient, but less reliable.
Which glasses lenses are best to choose?
There is a lot of different glass and high-quality organics that help protect vision, complement the image and even create a special attractive accent in appearance, have a neat appearance and are suitable for people with varying degrees of vision distortion.

Features of choice for children
The main criterion is that glass is excluded due to the fact that it can break and scratch the skin and mucous membranes. When you come to optics, you should pay attention to transparent polymer - acrylic or polycarbonate. Metal frames are also excluded. It is too hard, can cause allergies, bend and ruin delicate parts. The frame should be soft, monolithic. It is desirable that the frame be on flex hinges, which will prevent distortion, even if the child removes it with one hand.
For active sports
Sports eye accessories must provide a clear picture of the surrounding space so that the athlete can accurately calculate the coordination of his movements. To achieve this, most specialized sports accessories are available with an anti-reflective coating. To ensure that the frame fits tightly to the face, it is equipped with silicone gaskets on the nose folds, rubber temples and made at a certain bending angle. A special neck strap helps to secure the frame tightly on the face.
When choosing types of professional glasses, it is necessary to take into account the athlete’s occupation:
- For cycling and motorsports, polymer inserts with diopters are preferred. The degree of shading of the glass should not be higher than 1–3. It is better to choose a gradient mirror coating with yellow, gold, green or sea green spraying.
- For swimming, the best lens material is polycarbonate with a hydrophobic coating. The color of the glass is selected depending on the pool.
- To play tennis, volleyball, badminton, glasses must have a UV filter. The frame is a semi-rim so as not to narrow the viewing angle.
For motorists
Glass lenses are contraindicated for car enthusiasts. The optimal material is plastic or fiberglass (polycarbonate, Trivex). Lenses must be transparent so that the degree of light transmittance is not reduced. For daytime driving, polarized options are suitable, which effectively protect against the blinding sun, glare on wet asphalt or on buildings. For night driving, it is advisable to buy anti-headlights with yellow or orange lenses.
