Reliable. However, it is now too expensive and not suitable for wide application, and it can only adjust the power in real time to the need, and cannot add custom correction (for example, myopic people slightly help focusing, so that the eye muscles are relaxed regardless of whether they see near or far, so as to reduce the degree of myopia), it is better to wear glasses with low points and avoid wearing them for a long time.
According to the optical principle of junior high school, it can be known that if you look near for a long time, after the ciliary muscle is tense for a long time and causes rigidity, you can see clearly in the near and unclear in the distance. Myopia is overfocused, to be defocused, with a concave lens; Hyperopia is overfocusing, to focus, use a convex lens.
After wearing myopia glasses, the visual focus is finally defocused to five meters away, if you look at the near place for a long time, the ciliary muscle continues to tense, so that the focus is focused to within five meters, at this time, the refractive power is about equal to the original 100 degrees plus glasses 100 degrees, when wearing glasses five meters away and you can't see clearly, the mirror power is doubled, and the cycle of myopia is more serious. Therefore, low power should not be worn for a long time, just look at the distance belt.
Glasses should be low rather than high (about 25 degrees low), (100-200 for low degrees) should be worn short, not for a long time.

Discuss continue to study, if you really don't want to learn, machinery should be a good choice, although dirty and tired, find a master, follow him every day, the Yang family has no problem making a living, if you want to have a car, a house and money, you have to continue to learn to become a senior technician. Now no one wants to do technical work, and there will still be a shortage of skilled workers in ten years. In addition, it is also good to learn car service, and it is certain to make money.
If you are interested, tour guide (eloquence is good), chef (unless you are very outstanding or your own boss, the general is not very good), hotel management, logistics (this is very hot, but there are many people who learn), you can also open a small shop, the kind of chain, make money first.

-
This one is very, very good, and it's great.
-
From wearing it once, it's too good. I don't believe that I went for a few days in a row and am now working on this project.
-
The effect is very good, I have done it in the experience store for a few days, and the old people have a good effect.
-
I've used this and it works well.
In this case, it is best to go to the hospital for examination, and the doctor will give a reasonable opinion. But if strabismus occurs, then it must be taken seriously. >>>More

Optometry is only in the optical store is completely free of charge, in the hospital is generally charged, a smaller hospital or no special optometry department generally only charges a few dollars for the examination fee, in the eye hospital, especially the kind of large hospital examination, there are special optometry departments, all kinds of instruments are more complete will be slightly more expensive, like I used to practice in a large eye hospital in Zhengzhou when it was 15, 20 yuan in different situations, in general, just optometry is generally not too expensive. However, in large hospitals, optometry generally requires dilated pupils, and it will be difficult to see clearly for a period of time, so you should pay attention when driving.
