Optical characteristics of sunglasses Polaroid

What is polarization?

The bright rays of the sun are reflected from various smooth surfaces: water, snow, car glass.

This light creates waves that travel in vertical and horizontal directions. Vertical light is beneficial to the human eye, but horizontal light is not at all. Therefore, inside each lens there is a layer of vertical polarization, which prevents horizontal light waves from penetrating.

Polarized glasses significantly reduce blur and increase the contrast of what you see.

Non-polarizing sun lenses do not solve the problem of glare when driving. While driving, polarized sunglasses block solar interference on the road surface and uncomfortable reflections from the glass. Good quality polarized lenses (in the online store GLAZEY only these) also perfectly block ultraviolet radiation up to 400 nm.
UltraSight™ lenses consist of 9 layers. Each performs its own unique function. A polarizing filter is inserted in the center, which absorbs harmful to the eye UV rays. Next to it are shock-absorbing layers, which give the lens strength and flexibility. Scratch- and impact-resistant layers on both outer sides complete the lens structure.
The reaction time of drivers wearing polarized sunglasses was 20% faster than the reaction time when driving without sunglasses and 40% faster than that of drivers who were wearing regular sunglasses. Faster response means stopping distances are 6 meters shorter than when driving with non-polarized sunglasses, and 3 meters shorter than when driving without glasses.
In the production of glasses we use: for frames - an alloy that has high strength and resistance to corrosion; for the lens - a lens with a protective coating that prevents UV (ultraviolet) radiation.
Nose pads are made of hypoallergenic high-quality material.
Terms of use:
- it is recommended to store in a case;
- if the temples touch the inside of the lenses, wrap them with a napkin;
- remove and put on glasses only with two hands to prevent loosening and breaking of the temple fastening mechanism;
- do not wear glasses directly on your head - this can lead to their deformation;
- make sure that the cloth you use to clean your glasses does not contain dust, sand or anything that can scratch the lenses (wash it regularly with soap);
- in case of heavy contamination, wash the frame with soapy foam, rinse under water and wipe with a clean cloth.
Don't allow:
- contact with sea water, hairspray or perfume, especially if your lenses have a mirror coating;
- storage without a case: in a purse or pocket, on the dashboard of a car, where the glasses may come into contact with various objects;
- Avoid long-term storage of glasses in high temperature conditions. Direct sunlight (especially through a car window) can cause irreparable damage to your lenses and frames.
Guarantee period:
6 months from the date of purchase of the product, subject to the operating rules and conditions of effective and safe use.
Best before date:
Is not limited.

How are polarized glasses different from regular sunglasses?

UltraSight™ lenses are exclusive to Polaroid Eyewear.

Thermofusion technology allows the production of only optically correct lenses. The adjustment occurs automatically during the bending process. Your vision will not suffer from distortion.

Selecting lens color

The first buyers of Polaroid sunglasses, back in the 1935s, did not have this option. They were presented with only one lens color option – green. And it is no coincidence that it was considered optimal for most life situations. With modern models (with a wide variety of lens colors), you can afford to choose those that you think best suit your skin tone, hair color, eyes, style and your basic requirements.

Below are examples of how to match lens colors to different conditions that Polaroid sunglasses are sure to help you with.

Dark gray (shading category Cat. 3) – minimally distort color, a good option for bright sun. Suitable for general purpose sunglasses. Provide natural color reproduction in the environment. Good for driving, all kinds of sports and outdoor activities. Glasses with gray lenses will be comfortable both in sunny and cloudy weather.

Brown and amber (dimming category Cat. 3) - improve image contrast. Enhances the perception of depth in space. Suitable for playing golf, tennis, fishing, mountain and water sports, for any type of physical activity. Recommended for wearing in moderate cloudy and sunny weather.

Dark green (shading category Cat. 3) – have the property of reducing eye fatigue during prolonged concentration of gaze. Reduces disturbing shine, but makes shadows clearer. Suitable for a variety of active outdoor activities. Recommended for both cloudy and sunny weather.

Lenses with gradient effect(blackout category Cat. 3) – driving a car in them is a pleasure, and reading in the sun becomes much more convenient. All this is due to their property of limiting the overhead light of medium brightness.

Blue and purple(dimming category Cat. 3 or Cat. 2) – look very stylish, add contrast in dim lighting. Reduces glare. Helps you see the outlines of objects better. They are also used by fans in open stands when playing golf. Suitable even in fog and snowfall.

Yellow lenses (shading category Cat. 3 or Cat. 2) - improves visibility in fog and atmospheric haze. Perfect for lovers of fishing, skiing, tennis, hunting, and flying aircraft. Recommended in the morning and evening hours.

Clear white lens colors(shade category Cat. 0) – Present only in the Polaroid SPORT collection, included with glasses with additional interchangeable lenses. Suitable as a fashion accessory. They will save you from insects by riding a bicycle or motorcycle at dusk. They will not protect your eyes from sunlight.

For driving – copper color (light transmission 16%)

For fishing – brown (13%)

For relaxing on the beach - gray (15%)

Maximum protection against polarized light while maintaining natural color rendering – brown (27%)

Information for drivers.

When you're driving, glare doesn't just make it difficult to see - it creates dangerous driving situations. Even the most careful drivers are vulnerable without polarized sunglasses!

Wearing sunglasses with polarized lenses helps block glare, greatly improving driving safety.

Polaroid Sports Collection

Created specifically for people leading an active lifestyle. Sports glasses represent the embodiment of the latest research in the field of ergonomics, a high level of quality and manufacturability of the materials used. The frames provide front and side eye protection, are highly durable, and have polymer lenses that provide 100 percent protection from ultraviolet rays.

Do you like cycling or fishing?

Read our tips and you will look at equipment for your favorite hobby in a new way!

1. To protect yourself from splashes and dust, there is no better way than to wear tight-fitting sports glasses.

2. The main “enemies” of a cyclist are not only the blinding sun, dust and wind, but also tree branches. Fishermen should also keep an eye on the trajectory of the fishing hook in the air. Another plus for tight-fitting glasses!

3. Protect your eyes from glare on horizontal surfaces using polarized lenses. It is from these glares that the eyes quickly get tired and visibility deteriorates.

4. Horizontal light, affecting the eyes day after day, can cause early cataracts.

5. A polarizing filter is especially important for those who constantly look at wide horizontal surfaces. For skiers it's snow, for rowers it's water, for cyclists it's asphalt. Fishing glasses should also be polarized.

Mirror glasses

A very popular trend this season, and they won’t go out of fashion for the next couple of years. The mirror coating is applied in a special way and consists of tiny particles, resulting in a mirror effect.

There are no clear boundaries to this trend. Mirrored glasses are quite versatile and easy to fit into any look. Lenses of various shades are relevant. A great opportunity to play with colors and accessories to add bright accents to your style.

Children's eyes need protection.

Children under 3 years of age should start wearing sunglasses. Scientists stated this. What is this connected with? The fact is that the lens of a child’s eye is more transparent than the lens of an adult. This results in more harmful sun rays reaching the baby's retina. Subsequently, this can cause the development of serious eye diseases. According to statistics, a person receives the largest amount of harmful rays during childhood.

Transmission of UV radiation by the lens depending on age:

After birth – 95%

At 6 months – 80%

At 8 years old – 75%

At 25 years old – 20%

Polaroid creates lightweight and durable sunglasses for its little customers. They will reliably protect against exposure to potentially dangerous solar radiation and injury. Children cannot help but appreciate the effect of a polarized lens during games and sports. Hypoallergenic.

Production, operating rules, shelf life of sunglasses in the online store GlAZEY.

Sunglasses are made from materials approved for use by the Ministry of Health of Ukraine. They also passed the state sanitary and epidemiological examination.

The first glasses were released by Polaroid in the 30s of the last century. These are the safest and most comfortable sunglasses today. Polaroid, thanks to many years of experience, has improved manufacturing technology in combination with stylish Italian frames.

Polarization - what is it and why is it important?

As is known, polarized light, unlike daylight, spreads only vertically and horizontally. It is in the vertical plane that light is found that is useful to the human eye.

Glare, which, when light comes into contact with water or other mirror surfaces, is formed in a horizontal plane, create interference and cause eye fatigue. Polaroid is used to protect against glare and the harmful effects of ultraviolet rays. Glasses that improve contrast perception and color rendering allow you to feel comfortable.

Due to the violation of the protective layer of the earth, dangerous to human eyes radiation. Polaroid has 100% solved this problem. Sun protection lenses limit the penetration of dangerous rays and completely eliminate harm.

Technology for making lenses for sunglasses

Manufacturing technology designed for innovative production, which allows you to reliably protect the polarizing layer from damage and give it a shape that reduces its thickness towards the edge.

Polaroid sun protection lenses are made up of multiple layers that fit together perfectly. That is why the glasses have a very high quality characteristic.

What are the advantages of Polaroid lenses?

​In the middle of the lens there is a polarizer film. This is the main element through which protection occurs. The film is surrounded by a layer that eliminates the damage of ultraviolet radiation, absorbing it. Next comes the coating, which makes the lenses flexible and durable. The next layer is unique, it is resistant to scratches and other mechanical damage.

In 2006, Polaroid released a lens that confirmed the company's leadership in sunglasses and set modern standards for quality.

The lens was made in the UK, in its production the latest technology of polishing under pressure was used. It is able to absorb some amount of infrared radiation, which makes wearing glasses comfortable and reduces the heat transmitted.

Convenience and durability of use is due to the additional layer and quality of Paloroid; the glasses do not wear out for a long time, break less often and always look like new.

Eyewear for everyone, combining technology and fashion

Sun protection glasses are popular for over 69 years. At first they were used only by athletes and water sports enthusiasts. Today, the scope of application has expanded; sun lenses and Polaroid have begun to be used not only by professionals, but also by ordinary people.

Types of sunglasses produced by Polaroid

• for men
• women's
• sports
• children's
• unisex

By the markings on the original Polaroid sunglasses, you can understand who they are intended for, from which collection and what material was used for the manufacture of. The first letter contained in the license plate indicates the collection and for whom this model is intended.

Choosing sunscreens eye protection products, a person wants to look stylish and original, formal or informal, all these tasks are successfully solved by Polaroid. Glasses should be comfortable and fit well, the frame should be light and durable, should not break, it’s good when the price matches the quality.

It is worth buying sunglasses of the shape that suits your face type. Choose the color according to the purpose of use: for very bright sun, for fishing, driving, etc.

On what material? stop when choosing sun lenses Polaroid is a matter of taste. Glass or plastic? Plastic, if it is of high quality, can be no worse than glass, and it is also lighter and stronger. Children are not recommended to purchase Polaroid glass glasses. The price of such lenses is much higher, they fog up faster and are much heavier than plastic. Due to the increased risk of injury, sunglasses with glass lenses are not recommended for active sports.

The difference between Polaroid sunglasses and fakes

A fake Polaroid can be distinguished from an original by several features:

1. According to the number on the bow, it should not be erased and consists of 4 digits
2. The brand inscription must be present. Polaroid sun protection lenses, the official logo of which is not printed, are fake.
3. A passport book with a code that matches the number on the shackle is a distinctive feature of the original
4. The low price and quality of individual parts suggests that this is a fake Polaroid

They have long become a world classic in the “optical” market. This is due to the unusually high popularity, impeccable quality and unique features of the products. The reason for their continued popularity is their versatility: these are glasses for representatives of different ages, social classes and stylistic trends. Polaroid glasses are created with people in mind: for their comfort and preservation of vision.

For a detailed review polaroid sunglasses Let's take a tour into the world of Polaroid.

What is the origin of the Polaroid brand?

In modern times, sunglasses came along with the popular Polaroid brand. The Polaroid Eyewear company has been producing lenses with a polarizing effect for about eighty years. The company's sunglasses quickly found their buyer and expanded their sales geography to the whole world. Today, the Polaroid concern is the largest manufacturer of optics with an impeccable reputation. Designers and technologists are constantly improving product manufacturing technology, making it more modern and innovative.

All these achievements were started by the American Edwin Land, a technician by training. In 1929, he invented the main component material for future branded products. It was a polarizing lens. This product was called “Polaroid.” The principle of its operation formed the basis for the development of unique sunglasses.

About Polaroid sunglasses. The main principle of glasses design

The secret behind the huge demand for Polaroid glasses is the use of polarized lenses. This is a structure of several layers, between which a polarizing filter is placed. It is capable of preventing horizontally directed light from passing through the glass of sunglasses.

Light can be horizontal or vertical. Reflecting from flat surfaces, the light becomes harmful to the human eye. Vertical light, on the contrary, helps to recognize colors and shades.

A polarizing film, or filter, installed in the lens blocks the entry of horizontal rays to the retina. And, thanks to the vertical direction of light, the shades become brighter and the image clearer.

Polaroid recently teamed up with RealD™ Ink to release 3D glasses. This further enhanced the effect of the polarizing lens and made it possible to create three-dimensional visualization of the surrounding world.

Thus, thanks to the development of Dr. Edwin Land, they provide comfort and protection for vision.

Points guarantee:

• no glare,
• clear picture image and high contrast,
• undistorted color palette,
• duration of wearing glasses without eye fatigue,
• safety regarding ultraviolet radiation.

Modernization of the company led to the use of Thermofusion technology. This is a process where the polarizing layer narrows from the center of the lens to its edges. This leads to protection from lens overheating and significantly increases the service life of the glasses.

Polaroid sunglasses are the brainchild of a company that has embraced innovation, consumerism, and a reputation for eighty years. Polaroid – perfection in every detail!

Polarized glasses are glasses whose lenses have a polarized filter. So far, everything seems to be clear, or vice versa, nothing is clear, but let’s understand what polarized glasses are and why a polarizing filter is needed.

Let me make a reservation right away: all the tests for polarization of sunglasses that are described in this article were tested on this model of glasses. This model of polaroid glasses is inexpensive and very popular, so it was chosen for the test.

How to determine whether there is a polarizing filter in the lenses of your sunglasses or not? First, you need to understand what polarization is, and why this very polarizing filter protects your eyes.

Please do not confuse the polarizing filter in sunglasses (the use of this filter in sunglasses is not necessary) and the filter that protects the eyes from ultraviolet radiation (must be present in all sunglasses, otherwise why are they needed).

Some scientific facts about polarization

Daylight propagates in the form of electromagnetic waves oscillating in all directions of three-dimensional space.
Polarized light extends already in two-dimensional space, in horizontal and vertical directions.

In simple terms: light propagating in a vertical direction allows the eyes to perceive important information, recognize colors and contrasts. Horizontally spreading light creates optical interference (glare). For those who want to study in more detail the process of polarization of electromagnetic waves, it makes sense

Already in 1929 it was clear how to control light to reduce glare. The founder of the Polaroid Corporation was the first in the world to invent polarizing lenses for sunglasses. Today, almost all Polaroid brand sunglasses come with a polarizing lens filter.

For whom is polarization important in sunglasses?

Polarized lenses in sunglasses are loved by many; their very strong effect is noticeable for those who spend a lot of time on the water. Glasses with a polarizing filter are very popular among people who are keen on fishing; read about this in detail in the post “How to choose polarized glasses for fishing”. It is the waves on the water that create a huge amount of blinding glare, which polarizing lenses in sunglasses cope perfectly with.

Also, everyone who drives a car can remember the blinding effect of wet asphalt in sunny weather, etc. So, many motorists use polarized sunglasses to drive a car and they really like these glasses.

Where to buy polarized glasses

To avoid buying fake polarized glasses (of which there are many on the Internet), try to buy sunglasses in trusted online stores.

Where to buy original polarized glasses:
In RuNet, the leader in sales of original sunglasses is Lamoda. This online store has a large selection of original polarized glasses (lamoda does not sell fakes).

Where to buy fake polarized glasses:
If you purposefully want to buy a fake, then the undisputed leader in this matter is the AliExpress website.

The AliExpress website has a huge selection of fake sunglasses; you can choose from more than 30,000 models. For example, counterfeits of sunglasses from the famous Ray Ban brand on AliExpress can cost 300 rubles and free delivery to the post office.

Before purchasing Ray Ban sunglasses, be sure to read the following articles:

Advantages and disadvantages of polarized glasses

The price of high-quality polarized glasses can be quite high, and there is no point in buying cheap fakes. Let's figure out whether it's worth paying a high price for glasses with a similar filter, or whether it's better to buy regular sunglasses with a UV filter.

It is worth noting that along with the advantages, polarized glasses also have a number of disadvantages that can negate all their usefulness. Some people who use polarized glasses complain of constant headaches. Is this related to wearing polarized glasses or not? Without a medical examination and examination of such glasses, it is impossible to understand the causes of headaches.

Read on for all the other benefits of polarized glasses.

Benefits of polarized glasses

• Polarized glasses perfectly remove glare and reduce light intensity;
• when using glasses with polarization, the contrast of what you see increases;
• polarized glasses reduce eye fatigue;
• polarized glasses are simply irreplaceable for certain types of activities (driving, fishing, skiing, etc.);
• Glasses with a polarizing filter are recommended for people with light hypersensitivity.

Disadvantages of polarized glasses

• the price of polarized glasses is significantly higher than regular sunglasses;
• polarized glasses reduce the readability of road signs (weaken the reflected light), side lights and brake lights;
• Polarized glasses make it difficult to view information (darken the image) on a liquid crystal display (mobile phone with an LCD display, GPS navigator, tablet, etc.).

Two easy ways to determine if your sunglasses have a polarizing filter

It should be remembered that a polarizing filter is a thin film that is contained in the lens of your glasses, depending on the quality of the lenses in your glasses, the service life of the filter also depends.

For example, the polarizing layer (polarizing film, polarizing filter) in the original glass lenses of Ray Ban glasses is sealed between two outer lenses (), such a filter lasts throughout the life of the glasses. Oakley's patented polycarbonate lenses feature a polarizing filter at the molecular level of the polycarbonate (essentially the entire lens is a thick polarizing film). Inexpensive Polaroid glasses also have their own technology for producing polarized lenses; about Polaroid lenses, read the link.

In fakes of famous brands and cheap glasses, a filter is used in the form of a thin film on the surface of the lens, which wears off over time and the polarizing effect disappears. Try to buy glasses in trusted online stores that sell original products.

When purchasing sunglasses, it is very easy to determine whether there is a polarizing filter in the lenses! There are two simple ways to do this.

First test of the polarizing filter.

Before purchasing, ask the seller for another pair of polarized glasses and match them lens to lens. Next, turn some glasses 90 degrees relative to the others and look at the light (the axis of rotation should pass through the centers of the lenses). If the glasses are polarized, then the clearance in the lenses will become dark, but if the glasses are simple, then nothing will change.

Second test of the polarizing filter.

Take polarized glasses, look at any LCD monitor (cell phone display or payment terminal monitor) and rotate the glasses 90 degrees relative to the monitor. If the lenses of the glasses have a filter, the image will darken or become completely dark. If the glasses are simple, then nothing will change.

One small note, this test works exclusively with LCD screens.

Where else are polarizing filters used?

The use of polarized light and polarizing filters in everyday life is much wider than just use in sunglasses. Here are a few everyday examples that many people use in their homes and do not think about the fact that this is polarization.

3D glasses- glasses for watching movies with 3D effect, work on polarized image separation. It all works very simply, the visible image (on the TV screen) is divided into stereo pairs (two separate images), which have different polarization (for example, the left image has vertical polarization, and the right one has horizontal polarization).

3D glasses also have two lenses with different polarization (for example, the right lens has vertical polarization, and the left lens has horizontal polarization). The eyes each see their own image, and the brain combines it all together and creates the illusion of volume.

Polarizing filters for cameras- the filter consists of 2 rings, one of them contains a polarizing filter, by rotating which you adjust the degree of polarization. It works the same way as with sunglasses, your photos will be more saturated. For example, if you are shooting a landscape, the clouds will stand out in more contrast against the blue sky, and the vegetation will look more lush.
