Do smart zoom glasses with good eyesight really work?

I am the optometrist of Huachang glasses. I have been engaged in optometry 15 years, and I am also very disgusted with the advertising of good eyesight. Good eyesight is a progressive multifocal lens, which can reduce children's reading fatigue in principle, because ordinary glasses will look too deep in the distance, and progressive multifocal lenses will automatically zoom according to the distance you see. To some extent, it should slow down the speed of myopia deepening, but it is a scam to say that it can reduce the degree. Some unscrupulous merchants deliberately raised the degree when they first matched it, and said that they would lower the degree when they re-examined it. Imagine, if the degree is reduced, how can they continue to wear this pair of glasses? It can be said that at present, there is nothing in the world to ensure that children's myopia will be reduced except laser surgery (laser surgery will have certain sequelae). The kid above said he was 19 years old. If he uses his eyes normally at this age, he should set his shape immediately, which means he won't deepen his degree. If his eyes have enough rest, he will become better without any treatment. In addition, TV has two prices, 999 and 1599. If you don't expect the effect in the advertisement, it's good to match a pair.
