On the one hand, orthokeratology lens can easily make the cornea inflamed and perforated, and even lead to blindness of the eyes. On the other hand, the deprivation of oxygen in the eyes causes the eyes to become dry eyes. These dangers are no longer simply a theoretical possibility, but real risks.

It occurs after many years of having to stop wearing orthokeratology lenses. Orthokeratology lenses are dangerous, and it is better not to wear them.
