how does orthokeratology and overnight vision correction work?

706 views

My friend briefly mentioned that he uses ok lenses (orthokeratology lenses) and that it’s a part of his daily nighttime routine. Does this even work, and can it be used to fix my occasional micropsia?

Oh yeah, I have used this for 5 years now I think. Yeah it works. Afaik it is mainly used to treat myopia (near sightedness) and astigmatism but they really are specialised to each person so they might work on more. 1,500 nights of sleeping in lenses. Each night it squeezes on your mishapen eye, over a week an untreated eye becomes perfectly sighted (or really, overcorrected in the morning so that the correction lasts longer). If I don’t wear them one night, my vision will visibly worsen the next day. Feel free to ELI5 to me what micropsia is/what it has to do with eye shape and I might be able to help.
