Generally the reasons behind myopia are changes in the shape of the eye or the lens, not something the muscles are doing wrong. (And a contributing factor with age is the decreased flexibility of the lens over time).
- RealityVoid 5y agoMost naive expectation is if myopia changes the shape of your eyes, just squish them a bit!
- DoingIsLearning 5y agoYou joke but there are orthokeratology lenses which do just that. It's a contact lense worn overnight which compresses your eye during sleep.
- afterburner 5y agoThat'll squish the lens, but the overall shape of the eyeball is what causes the myopia in most cases.
- DoingIsLearning 5y agoTecnically the crystaline lens is in an anterior chamber inside your eye, so these contacts can't really squish the lens itself. These contact lenses are squishing against your cornea. So in actual fact an anterior portion of your eyeball is being re-shaped.

- ivanb 5y agoTo people considering LASIK I want to say try ortho-k first. You'll get the sharpness, the halos and the whole experience but at least it will be reversible. I've been on ortho-k for around a decade.
