Orthokeratology, as its name implies, changes the curvature of the cornea. Some people have low myopia. After one use, their eyesight can be maintained for a long time. In the meantime, they can't wear them. After stopping wearing, the cornea itself has memory function, and the degree will retreat, which is a normal phenomenon. If there are no special circumstances, it is still necessary to overcome difficulties and stick to wearing them, so that the effect will be good. If you need to stop at 1 day, your vision will not be greatly affected and your memory function will not be greatly affected in a short time during this 1 day. But I still have to wear it after that.
