The choice of suitable glasses must be taken as seriously as possible. The effectiveness of vision correction and how convenient it will be for you to use them depend on this. Incorrectly chosen glasses can cause discomfort and distort the world around you.
How to choose glasses is a question that cannot be answered briefly. There are many factors to consider when choosing.
What are glasses made of?
Glasses are made up of lenses and a frame.
If the product is intended for vision correction, then its lenses have a certain refractive power, which is called “optical power” and is measured in diopters. It is due to it that you see the world around you more clearly, without distortion. There are also glasses without diopters, for example, sunglasses or for working at a computer.
The frame is needed to hold the lenses in front of the eyes. Its main elements are:
- Frame – necessary for fixing lenses;
- Temples – thanks to them, the glasses are kept on the head;
- Bridge, bridge, or bridge of the nose – connects the two parts of the frame to each other;
- Nose pads – needed to better fix the glasses on the face.
How to choose eyeglass lenses?
To the question “How to choose glasses?” It is impossible to give an exhaustive answer without paying attention to the choice of lenses. If you need eyeglasses for vision correction, the choice of a suitable model must begin with a visit to an ophthalmologist. He will determine what kind of visual impairment you have, and what is its degree.
In this case, not only a table with letters and symbols printed in a font of various sizes is used, but also special devices. The specialist indicates the parameters of the lenses you need in the prescription, according to which you will decide which spectacle lenses to choose.
The most common eyeglasses are:
- For a distance – designed for constant wear and allow you to clearly see objects that are at a great distance from you;
- For near – needed for reading or work performed at a relatively short distance from the eyes;
- For a medium distance – for example, to watch tv or work at a computer.
Frame materials
All frames can be divided into three main categories:
- Plastic;
- Metal;
- From exotic materials, such as wood or horn.
Different metals and polymeric materials have different properties. For example, frames are made from polyamide plastics, the main advantages of which are lightweight, strength, flexibility, and resistance to high temperatures. For the manufacture of glasses, stainless steel is used – the frames made from it will be durable, hypoallergenic, but relatively heavy. Talking about frames, Rose gold.glasses from glasses shop are very in the style statement these days, pick yours to get updated.
There are also combined options. Many manufacturers offer frames made of metal and plastic, combining the advantages of different materials. Other solutions are also possible, for example, glasses made of plastic, which is called “optical”, – such frames can contain various inclusions: pieces of metal and leather, crystals. They will appeal to those who love unusual design solutions.
How To Choose a Frame Size?
How to choose glasses by size? As a rule, the manufacturer indicates the main parameters on the temple or bridge. This is:
- Aperture width,
- Bridge width,
- Earpiece length.
They must be taken into account, but, of course, it is worth not only focusing on numbers but also trying on the frame.
There is a basic principle that needs to be taken into account: the width of the frame should approximately correspond to the width of the face and not go beyond it (or go out, but not much). True, there is an exception to this rule – design models created with a deliberate violation of this principle. But they are intended primarily for those who like to create catchy, contrasting images and attract attention.
