Let’s understand this first, the reason short-sightedness increases is strongly related to the length of the eyeball, or the eye axis for short. As the eye axis grows, short-sightedness will tag along and increase
Long story short, the reason we get short-sightedness is because the light entering the eye gets focused on the wrong place. By wearing glasses, you can move this focus to the retina. But, our eyes are not that simple, it actually has plenty of focus, not just one.
When you put on the glasses, there are still some lights that will fall at the wrong area. Naturally our retina will then try to find the clearest focus, causing the retina to grow longer in length. As the retina grows, the eye axis eye increases and short-sightedness increases as well.
On the other hand, Ortho-K lens, a specially designed lens and it is worn in the center of the cornea. It’s pulling the retina hard, making sure that it doesn’t grow that fast. Simply put, Ortho-K lens causes the focus to be on the front of the retina. As such, the retina will not grow backwards (eye axis increases), only forward (eye axis decreases)
Okay, that’s all for today. This is how the Ortho-K lens controls short-sightedness. Hope this little knowledge is helpful to you!
