Should I wear glasses all the time for myopia?

Wearing glasses is more to correct your vision and protect your eyes, so as not to worsen myopia. If you are nearsighted but don't wear glasses, it will have a lot of impact on your eyes. First of all, after a person is nearsighted, seeing distant things requires a lot of adjustments to the eyeballs, which will make your eyes tired easily. Over time, your myopia will increase quickly. When we are nearsighted, sometimes the myopia of the two eyes is not the same. If we do not wear glasses and correct vision, this will affect the normal development of vision. The difference between the powers of the two eyes may become larger and larger, which is easy to cause a squint. After myopia, if you want to see far away things clearly, you need to squint your eyes harder to see clearly. Therefore, some nearsighted eyes often squint when they are not wearing glasses. However, the action of squinting will cause the upper eyelid to form a pressure on the eyeball, and squinting for a long time can easily cause amblyopia. Squinting your eyes for a long time will also make your eyes smaller and affect your appearance. Therefore, once your myopia exceeds 200 degrees, you must wear glasses in time.

Why do you need to adjust your glasses?

To make wearing comfortable, glasses do not overpress the nose and ears. After wearing glasses, it is advisable to have no tenderness at the contact point and not to slide down the head frame. The frames have to be made fundamental adjustments after assembly to meet fundamental standards.



Eyes Optometry

Before buying glasses, it is recommended that you must go to a regular eye hospital or optometry organization, and carefully record your own degrees. Optometry is the focus of attention for glasses. Teenagers use more eyes and refraction changes quickly. The most accurate refraction data can be achieved by optometry before matching glasses. Moreover, correct optometry is not only to determine the degrees of myopia but to understand other conditions like astigmatism and pupil distance. Now comprehensive optometry is widely used, and the results of optometry are more accurate.

Chemically stable, the material is widely used in artificial joints. One thing to emphasize, the titanium welding process is very demanding. The production cost of titanium and titanium alloy glasses is high, and the process has special high requirements in cutting, stamping, welding, and electroplating (for example, welding must be completed in a vacuum), so the price is relatively expensive.
