Orthokeratology 2
According to the girl who is also shortsighted, she has a treatment with special contact lenses, which is called “Orthokeratology”. We know that wearing normal contact lenses recover one’s sight by adjusting the focus point inside of eyeballs. As a matter of course, the lenses have to be on eyes while they are opened. In other words, the user needs them while he/she is awake or being active mostly in daytime. The girl, however, wears the contact lenses Ortho-K while she is sleeping in the night and wakes up in the morning with clear unaided vision, which stays even after removing the lenses. It sounds quite interesting, I thought. So I studied about it on several websites and found that Ortho-K helps to correct shapes of physical lenses on the front surface of user’s eyes.
