Functions of chameleon glasses

But glasses for chameleon glasses change their color in bright sun, thereby providing eyes with protection. This property is necessary for those people who have developed a fear of light or increased teardrop.
But in the chameleons, along with the function of protection, there is also a function of vision correction. Chameleon glasses are made with diopters for people with poor eyesight. True, until recently they were not popular, despite their convenience. The fact is that high-quality lenses began to appear relatively recently, replacing cheap counterfeits. Today, chameleon glasses for vision are made of high-quality glass, which provides good vision in the room and protect the eyes in the sun.
By the way, the degree of darkening chameleons may differ:

- 15-65% - average blackout (glasses, more often, gray color, such chameleon glasses are suitable for drivers);
- 30-85% - strong darkening (they are green and common among people with a high degree of photosensitivity).
How to recognize a fake?

- You need to put on your glasses and look around you. If the lenses are good, then the colors will retain their naturalness. If a fake, the colors will become brighter, or, conversely, fade.
- Take a good look at the edge of the lens. If the color of the rib is light, it is just a spray, which, most likely, very quickly erased. A "real" lens should have a dark edge. This means that it is made of photochromic glass, which is distinguished by its strength and durability.
