They became one of the details of the image of celebrities, thanks to which they gained great popularity around the world. Sunglasses-chameleons differ in their ability to change color depending on the influence of ultraviolet or illumination on the lens. This can be explained by the fact that the lenses of such an accessory are made of a special composition and are called photochromic. When ultraviolet light hits the windows, they begin to darken to protect from bright light, and become almost transparent in the room.

The appointment of chameleon glasses can be as follows: addition to the image and prevention of vision. If you need to choose glasses for medical reasons, then you need to consider the following details:

• Lenses, which are covered with a "female" photochromic component from ten to fifty percent, provide a weak obscuration. They have shades of brown.
• Darkening of an average degree, fifteen to seventy percent, is prescribed to people who suffer from tearing eyes or those who do not want to look at bright lights.
• For those who have a high sensitivity, it is necessary to select lenses with a fading of thirty-five to ninety percent.
• Glasses-chameleons with an anti-glare surface reduce the reaction of the lens to bright light and glare.

Any sunglasses give us the opportunity to feel comfortable, being in bright sunlight. The need for them is strengthened on spring and summer days, although in winter they protect against bright snow.
