CONTACT LENSES TO SLOW DOWN OR STOP NEARSIGHTEDNESS ESPECIALLY IN CHILDREN
Optometrists Are Fitting Children and Adults With Contact Lens to Wear At Night To Try and Reshape the Eye Possibly Slowing Down or Halting Myopia
A contact lens worn at night is being studied for a possible ability to reshape the cornea of the eye. Possibly slowing down nearsightedness, myopia, if the reshaping becomes permanent. But the technique is not without controversy.
"Nearsightedness is caused by a steepening of the cornea, the transparent tissue in front of the colored part of the eye. Night time contacts apply a slight pressure to the center of the eye, flattening the cornea."
"Adult users must wear the lenses every night, or their corneas will revert to their original shapes, and nearsightedness will return.In children, however, a few small studies suggest the reshaping benefits might be permanent". There are possible problems, indeed all contact lenses wearers have to be very cautious. There is a recent report of problems in Taiwan.

Children Using Overnight Orthokeratology Face Serious Risk of Microbial Keratitis
"While local conditions and the high prevalence of myopia and contact lens wear in adolescents in Taiwan may contribute to a higher incidence of pediatric microbial keratitis associated in this region, such a complication can also occur in similar patients in other geographic areas".
