Glasses it is a notion that alludes to glasses whose support is made behind the head or taking advantage of the structure of the ears . The glasses, meanwhile, are optical instruments which include two lenses to favor the vision of the person who uses them.

In general, the term is used in the plural: glasses . It is important to keep in mind that, in the language colloquial, glasses , glasses and lenses These are concepts that are used as synonyms, although each one predominates in different Spanish-speaking regions.

For example: “Where will I have left my glasses? I want to read the newspaper and I can't find them ”, “My mother gave me sunglasses for my birthday”, “Take off your glasses to play football: otherwise you can hurt yourself”.

The glasses consist of a frame or mount that holds the lenses. The frame has two sideburns that rest on the ears and a arc It is located on the nose. In this way, the lenses are left right in front of the user's eyes, which can correct defects in their vision, such as astigmatism wave myopia .

The frames of the glasses were originally made of steel or iron. Over time, manufacturers began using resins. At present, it is usual to resort to titanium alloys or aluminum . As for the lenses, we can find them manufactured with crystal , plastic polymers or polycarbonate .

Beyond the glasses whose lenses allow the correction of defects of the view There are also other types of glasses. The Sunglasses They feature dark lenses to block ultraviolet rays and protect the eyes from sunlight. In addition there are protective glasses that are used in certain trades and even in the field of sport.

Sunglasses are one of the most common accessories in times of heat, although in certain parts of the world they are worn throughout the year. It is a product that is very useful in summer to prevent sunlight from obstructing our movement on public roads, but it also serves to protect our eyes when we are outdoors. During summer vacations on the beach, for example, most people use them.

The cleaning Glasses is an activity that takes time to learn to master, especially since at first it is not easy to leave them absolutely free of stains and this causes discomfort that can lead to headaches or interference in a treatment. There are several products designed specifically for this task, although it is also possible to do it without them.

One of the most common products is marketed as a spray, in small bottles whose content is a liquid that cleans the glasses of the glasses without leaving residues that can cause scratches. Usually, these sprays are sold together with microfiber cloths, ideal for spreading the liquid and then drying the crystals for a good finish.

It is important not to spray too much liquid on the glasses, to avoid generating a "paste". Finding the right point takes time. There is also a product that instead of a sprayer consists of a bottle at whose peak there is a sponge that we must moisten and then pass it through each of the lenses. The final step is always to dry the glasses with the microfiber cloth until a spot is noticed.

An alternative to these products is to use tap water and a soap for the hands, although in areas of high lime this can cause marks on the crystals.
