Sunglasses are considered the most versatile and most fashionable accessory. They became one of the details of the image of celebrities, so they have gained great popularity around the world.
Chameleon sunglasses are distinguished by their ability to change color depending on the effect of ultraviolet light or lighting on the lenses. 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 gets on the glass, they begin to darken to protect against bright light, and in the room they become almost transparent.
The purpose 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 the following details must be considered:
- Lenses that are coated with a “feminine” photochromic component from ten to fifty percent provide slight dimming. They have shades of brown.
- Darkening of an average degree, fifteen to seventy percent, is prescribed to people who suffer from tearing of the eyes or those who do not want to look at a bright light.
- Those who have high photosensitivity should choose lenses with a dimming of thirty-five to ninety percent.
- Chameleon glasses with an anti-reflective surface reduce the reaction of the lens to bright light and glare.
- It is recommended to change lenses every few years. The halide that underlies them tends to wear out. After two years, he ceases to fulfill his function.
Chameleon glasses are universal and quite popular. They combine several qualities: protection from sunlight and vision correction. Any sunglasses give us the opportunity to feel comfortable being in bright sunlight. The need for them is increasing in the spring and summer days, although in winter they protect against bright snow. Universal and high-quality chameleon glasses appeared on the market relatively recently. Now you can find many low-quality fakes that are sold at a low price.
Photochromic glasses are divided into two types: male and female. Female models look elegant, the frame is decorated with decorative elements, the lenses are small. Men's glasses are massive and restrained. However, there are options decorated with a small inlay of the frame, but it is usually discreet.
Regardless of the purpose for which photochromic glasses are selected, some rules must be observed:
- Those with wide cheekbones and a face should choose a slimmer model.
- If the face is narrow, you need to choose square- shaped chameleon glasses with a thin frame for female models and with a massive one for men.
- Extraordinary personalities should pay attention to round small glasses of bright colors and irregular shapes.
Chameleon sunglasses perfectly complement the image of a business person. They should be combined with other accessories in a color scheme.
