Glasses have long ceased to be just an object that corrects visual defects. For a modern person, glasses are a stylish and fashionable accessory that allows, among other things, to position oneself in society. And if in the recent past glasses "like a pilot's" with a mirror surface of the lenses were relevant, now preference is given to glasses with a massive frame and non-reflective glasses.
Necessary
- - glasses;
- - the amount of 200 rubles, depending on the price list in the selected optics salon;
- - specialist advice.
Instructions
Step 1
If you have sunglasses or corrective glasses and want to deprive them of the reflective effect of the lens, you first need to decide on the choice of a special anti-reflective coating. AR coatings consist of several layers of inorganic compounds, the thickness and refractive index of which are selected in such a way as to reduce the reflection of light from the surface of the lenses and increase their light transmission. The cost of such coverage depends on the brand and manufacturer.
Step 2
You need to make sure that the coverage you have chosen is available in the optics stores of your city. The most common brands of special coatings are: Carl Zeiss, Essilor, Polaroid, Hoya. It is also worth remembering that some optics salons work with suppliers of rather rare brands of eyeglass lens coatings.
Step 3
Applying a special coating to spectacle lenses is the task of a competent specialist. The application process must take place in a sterile environment so that dust particles do not get between the lens and the coating - this can dramatically impair vision for no apparent reason. The AR coating consists of several thinnest layers applied to the surface of an eyeglass lens using special vacuum installations. The physical properties of the antireflection coating are designed so that the reflected light rays interfere with and extinguish each other. Coating takes several hours, depending on the availability of the technician.
Step 4
When applying a coating to corrective glasses, it is also worth paying attention to integral, that is, multifunctional coatings. They consist of a hardening coating, an antireflection coating (single or multi-layer) and a hydrophobic coating.
Step 5
After installing the anti-reflective coating, you must remember about special lens care products - microfiber cloths, cleaning sprays, disposable cleaning cloths. Also, the lenses must be protected from mechanical stress.
