In today's world, the number of people with poor eyesight is growing every day. In order not to see the world as blurry, people have to go to doctors - to find the right glasses for vision. The ophthalmologist will help assess visual acuity, tell you about the main features of using this method of correction and write out a prescription with which you can already contact the optician.
Selection of glasses directly in the store is now a reality
Even if you don't like going to the district clinics, it's not a problem. Modern salons-shops offer not only a wide selection of glasses, but also services for their selection. Many opticians have the necessary equipment for assessing visual acuity, eye condition, measuring the distance between the pupils, with the help of which a qualified oculist working there will help you choose glasses for vision. Your task will only be to choose the frame you like.
Frame selection: unknown subtleties
If you plan to wear glasses all the time, then don't take the first frame that comes across. It will depend on her whether you buy stylish glasses.for vision or get a model, like a neighbor's grandmother. Try on several options, choose the one that suits you the most. Pay attention to whether you are comfortable in the chosen model. Ideally, you should not feel the frame on the bridge of your nose at all, and the ears of the glasses should not press. The nose pads that many models are equipped with should be easy to adjust and install so that the glasses do not warp or fall off. Imagine: if you have, for example, myopia, then you will have to wear glasses for about 16 hours daily, the slightest discomfort by the end of the day will cause wild fatigue and irritability. In addition, do not forget that the frame must be reliable: it is better to pay a little more, but choose a more durable material. After all, you can’t insure eyeglasses from falls, from falling into children’s hands, or simply from the fact that someone can accidentally lean on them or even sit down.
Choosing the best lenses
Having decided on the frame, you need to start choosing lenses for eyeglasses. Many believe that this should be done by an optometrist. But the doctor only selects the right amount of diopters, determines the required distance between the centers of the lenses, but the material from which they will be made will have to be chosen independently. In modern optics, you will be offered classic glass and plastic lenses.
Advantages and disadvantages of different lenses
In our time, most people opt for ordinary glasses, because they do not become cloudy and can retain ultraviolet light. In addition, ordinary glasses can be made photochromic, and they will darken in the sun, while simultaneously acting as sunglasses. Glasses are also coated with special anti-reflective and polarizing compounds, thanks to which special glasses have appeared for working at a computer and for driving a car. But glasses for vision, whether they are men's or women's, with glass lenses also have disadvantages. So, the glass is quite fragile: one unsuccessful fall on the floor and you have to go to the optics for new glasses. Also, glass lenses are quite heavy and it will not be possible to avoid marks on the bridge of the nose when wearing glasses all the time. Plastic (polycarbonate) lenses are 2 times lighter than glass, they are quite difficult to break, but they can be scratched. In addition, only polycarbonate is suitable for people suffering from astigmatism, because it can be used to make double-curved diopter lenses.
