When the need to buy glasses (for vision, forcomputer, sunscreen) becomes vital, immediately a lot of questions arise: which lenses to choose, what shape and frame should I prefer, how much to spend on this accessory, in general, how to choose the right glasses?
How to choose the shape of glasses
First of all, regardless of whether there are glasses for sight or sunglasses, attention is drawn to the shape of the frame. How to choose the shape of glasses by type of face?
If the face is round, a square shape will fit andbright color rims. Round glasses, as well as glasses with a large frame, that cover most of the face (this is more true for sun glasses) will not work.
If the face is square, fit aviator glasses, as well as a frame with a cut round shape. It is not recommended for people with this type of face to wear glasses in square and rectangular frames.
If the face is long, elongated, it is bestwear large glasses, as well as large sunglasses with panoramic glass. Small sunglasses, as well as glasses without rims, will not suit this face.
The face is heart-shaped. Suitable for almost any type of glasses, especially glasses without rims. Do not fit darkened glasses for sight and too dark sunglasses. Also it is not recommended to wear glasses with a rim decorated with an abundance of small details - this frame will focus on the wide part of the face.
Oval face. All kinds of frames are suitable. The only nuance that needs to be taken into account in this case is that a small face in glasses with a thin frame will be lost even more, so in this case give preference to a more massive frame.
How to choose glasses for vision
A typical mistake when choosing glasses correctingvision, is that the focus is on choosing a frame, and the choice of lenses is the tenth thing. This is a fundamentally wrong approach to business. First of all, glasses for sight - this is a kind of medicine, and no medicine without a doctor's advice can not be prescribed. Therefore, before hurrying to the store for the rim, check your eyesight and find out what optical indicators your lenses should have. Wrong figures will lead to the fact that purchased glasses will further spoil your vision and will be a waste of time and money.
In addition to accurate indicators for lenses, you need to choosealso the material from which your lenses will be made. Here the choice is small: plastic or glass. The advantages of plastic are that it is lighter in weight, less injurious in case of lens damage, and also has the possibility of different design (for example, lens coloration). But there is a significant disadvantage - cheap plastic misses and can even strengthen harmful rays, thus spoiling the eyesight and eyesight. Glass lenses are thinner than plastic ones, and they are also stronger than them. In addition, glass lenses on sunglasses are more reliable in protecting from harmful emissions.
Choose a frame for glasses
In addition to the shape of the frame, which was mentioned above,You should also pay attention to the following several points. First, pay attention to nosoupory - they should not cause discomfort and strongly push on the bridge of the nose. It is best to choose soft, silicone nosopory. Secondly, the dimensions of the temples should fully correspond to the distance from the ear pin to the rim. Third, do not buy cheap metal frames. In contact with sweat, this frame can rust and cause an unpleasant allergic reaction.
How to choose sunglasses
For sunglasses, it is better to choose lenses fromplastic: they are less dangerous to the eyes in case of damage (and in summer, especially during the holidays, it is quite possible to break them). In terms of size is preferable to stop on the big glasses - they are much better protect from the sun. Of the colors it is best to choose dark gray and dark green hues of the lenses (pink color adversely affects the psyche and distorts all colors, and from blue shades to the owner of glasses may well become uncomfortable, as they stimulate the dilatation of the pupils).
In addition, for sunglasses it is recommended to choose a frame for the color of the hair. In this way:
Blondes and blondes should stop on black, blue or green. Also suitable frame "animal" color: skins leopard or crocodile skin.
Brunettes and brunettes are suitable for silvery or light golden tones.
Redheads can experiment with the frame, as they like: glasses will look great in lilac, and in light green, and in blue.
Gray-haired, however, should avoid only gray and yellow flowers. Rims of other colors will be to them to the person.
How to choose glasses for swimming
Before you start choosing glasses, you need to decide how often and professionally you will use them.
If you go to the pool irregularly or rarely, inexpensive glasses with a detachable nose bridge will suit you. These glasses will fully satisfy you in terms of comfort and tightness.
If you go to the pool often or seriouslydo swimming, then you better buy glasses with soft silicone or neo-prone gaskets. With these glasses you can swim for a long time and not feel discomfort for the eyes.
When choosing glasses for swimming, check that they arefit tightly to the face, but did not give you any discomfort. Glasses with silicone gaskets are pretty close to the skin, but can cause a "suction" sensation. People with sensitive skin should better buy glasses with microporous pads. She will not stick to her face as much as silicone, but she will not miss water either.
Some manufacturers recommend glasses forswimming with blue lenses because of their calming effect. But still it is recommended to choose the lens "for yourself".
