Eye exercise is the practice of voluntary eye movements. It is encouraged by the practitioners of the Bates Method and other unicorn farmers. They believe that eye exercises can "strengthen" the eyes, and by strengthening the eyes, myopia can be reversed. This is of course completely false and fails to account for the underlying causes of myopia.
There are two types of muscles of the eyeball, extraocular muscles and ciliary muscles. Extraocular muscles can be voluntarily controlled but the ciliary muscles are involuntary. As such, eye exercises can only work on the extraocular muscles, which are only responsible for eyeball rotation. However, myopia is a problem of focus and is caused by a combination of ciliary muscle spasm and axial elongation.
As the function of the extraocular muscles is to rotate the eyeballs to acquire subject fixation, it is self evident that it cannot affect focusing through accommodation. To reverse myopia, we need to work on the ciliary muscles instead. Ironically, the cause for myopia is not due to a weakened ciliary muscle, rather that it has become spastic from excessive near visual work. The ciliary muscles need to be made to relax through active focus for myopia to improve.
Active focus is what the unicorn farmers wish they knew how to do. Active focus is what eye exercises want to be when they grow up. Stop wasting time on eye exercises and learn how to active focus and improve your eyes. Unless you want to stay being a unicorn with glasses of course.
Eye exercise don't work for near-sightedness
- Not solving root issue.
- Effort is required past the first 90 days.
- Improvements happen about 0.75 to 1.00 diopters per year, so would take years of eye exercises.
- Eye sight improves slowly so you require habits not exercise.
