Glasses is a notion that refers to glasses whose subjection is carried out 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 note that, in the language colloquial, glasses, glasses Y lenses are concepts that are used synonymously, although each of them predominates in different Spanish-speaking regions.
For example: “Where have I 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 soccer: otherwise you may hurt yourself”.
The glasses consist of a frame or mount that holds the glasses. The frame has two sideburns that are supported by the ears and a bow that is located on the nose. In this way, the lenses are right in front of the wearer’s eyes, which can correct defects in his vision, such as astigmatism wave myopia.
The frames of the glasses were originally produced in steel or iron. Over time, manufacturers began to use resins. Currently, it is common to use titanium alloys or aluminum. As for the lenses, we can find them made 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 have dark lenses to block ultraviolet rays and protect the eyes from sunlight. There are also protective glasses that are used in certain trades and even in sports.
Sunglasses are one of the most common accessories in hot weather, 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 hindering our movement on public roads, but it also serves to protect our eyes when we are outdoors. During summer beach vacations, for example, most people wear them.
The cleaning Using 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 generates 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 in the form of a spray, in small bottles whose content is a liquid that cleans glasses lenses without leaving residues that can cause scratches. These sprays are usually sold alongside microfiber cloths, great for spreading the liquid and then drying the crystals to a good finish.
It is important not to spray too much liquid on the glasses, to avoid creating a “paste”. Finding the right spot takes time. There is also a product that instead of a sprayer consists of a bottle in 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 not even a stain is noticed.
An alternative to these products is to use tap water and a soap for the hands, although in areas with a lot of lime this can cause marks on the crystals.
