Night time contact lenses (Ortho-k), have been proven to slow down the progression of myopia in growing children, but I hear that there is very little research to back this. Do you have any research we can read up to learn more about Ortho k?

There are many studies that have been published in the medical literature proving the efficacy of Orthok in controlling myopia progression. This is a huge area of interest in recent years and there will be many more studies that will be published in time to come. This website http://www.myopiaprevention.org/references_orthokeratology.html compiles quite an extensive list of studies that have been published. You can click on the links and read the full version and/or abstract of each study.

Yeah I've read that Ortho K lenses are like braces for the eyes, improving eye sight quality. Like braces for the teeth, they are lenses that push and mould your cornea as you sleep. Here is a centre in Singapore who does this procedure. http://tituseyecare.com/services/orthokeratology/
