Photochromic chameleon lenses. Chameleon sunglasses for men and women. Pros and cons of photochromic glasses

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's happened 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 appearance They don’t give themselves away in any way. 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 eyesight. This is especially true in the summer, when the eyes even healthy person They lose visual acuity in bright sunshine and get tired quickly.

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.

Glasses with photochromic lenses are different from regular topics that they are able to change color according to the lighting around them. When indoors, these lenses look the same as regular lenses, with diopters. The same applies to night time, when these lenses are transparent, like any others intended for vision correction. But on the street, especially in bright sunlight, these glasses miraculously transform into sunglasses. And if you find yourself indoors again, the lenses become transparent again.

Photochromic lenses for glasses contain special substances, due to which, when exposed to ultraviolet radiation, their structure changes and the color of the lens changes. But as soon as the UV radiation stops, the glasses regain their transparency.

Previously, the rate of darkening was strongly influenced by air temperature, that is, not only illumination was the main influencing factor. If it was very cold outside, the lenses darkened quickly, and this did not always happen at the same speed on a hot sunny day. But now the manufacturers of these progressive accessories are using modern technologies to produce better photochromic lenses. Therefore, the air temperature no longer has such an effect strong influence both on the rate of darkening and on its degree.

Advantages of chameleons

Such glasses have a number of advantages compared to ordinary sunglasses or for vision correction:

Photochromic glasses are ideal option For myopic people who are forced to use it on the street sunglasses with diopters, and change them indoors to regular ones.

Mineral lenses have the following properties:

High level of UV resistance.

Since they are made of glass, they are more difficult to scratch.

But such glasses are more fragile and slightly heavier in weight compared to more advanced polymer ones.

Mineral lenses are more suitable for people with very low level diopter, since they can be made thinner due to high index refraction.

Properties of polymer spectacle lenses:

Plastic glasses are considered safer and more durable.

This material can be used to make lenses of the most various forms, thanks to this the choice of spectacle frames is expanding.

Their low weight compared to glass ones makes them more progressive and comfortable to wear.

Motorcycle glasses demonstrate an excellent price-quality ratio. Reviews allow you to decide on glasses from a specific manufacturer and understand which ones are better.

Modern technologies have made it possible to create special photochromic contact lenses, both with and without diopters. This is considered a great achievement of science.

Contact lenses are able to react much faster to changes in lighting compared to ordinary glasses. It is believed that the species is photochromic contact lenses- This the best option for athletes, for example tennis players.

So, photochromic glasses are a progressive accessory, ideal for people who love to drive. active image life. And also this excellent remedy for vision correction, which not only allows people with vision problems to see well visual organs, but also provides a protective barrier for the eyes from harmful ultraviolet rays.

But fashion-conscious people often buy these accessories for everyday protection of the retina from ultraviolet radiation. Uniqueness sunglasses The chameleon consists of 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 protection from ultraviolet radiation 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 at the slightest impact even after anti-shock treatment.

Chameleons with polymer lenses More suitable for everyday protection from ultraviolet rays, 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. Read more about photochromic lenses watch the video speech of the head of the company BBGR (France) M. Blagovestny:

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 such as farsightedness, myopia, age-related diseases For the eyes, 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 chameleons with diopters can also be used in extreme sports sports such as skydiving, skiing, cycling and motorcycling.
