The Science
Disclaimer: If this page seems like a foreign language to you, We highly recommend you go through our four-day email crash course or read through a couple of blogs.
Please keep in mind, This is ADVANCED stuff, we simplify everything in a MUCH easier format in regain20/20. This page is not meant for everybody.
Studies
Link + oversimplified summaries
Using natural STOP growth signals to prevent excessive axial elongation and the development of myopia.
-
Relatively brief periods of myopic defocus can overcome pressures towards increasing axial length
Does convergence, not accommodation, cause axial-length elongation at near? A biometric study in teens.
-
Convergence could be what causes axial length increase rather than the accommodation itself
Eye Exercises Enhance Accuracy and Letter Recognition, but Not Reaction Time, in a Modified Rapid Serial Visual Presentation Task
-
Eye exercises can improve cognitive visual performance, but not necessarily reduce axial length.
-
Could be part of the reason why improvement is observed in the bates method.
The Truth about eye exercises
-
Ebook that talks about the unorthodox category of eye exercises
-
Slightly outdated, but actually describes pseudo-myopia
Nearwork-induced transient myopia (NITM) and permanent myopia - is there a link?
-
Investigation of possible relationships between pseudo-myopia and regular axial myopia
-
Psuedo-myopia is short-lived
Chick eye compensate for chromatic simulations of hyperopic and myopic defocus: Evidence that the eye uses longitudinal chromatic aberration to guide eye-growth
-
Eyes will adjust appropriately for hyperopic defocus and myopic defocus.
-
Change in choroid thickness is used to guide axial elongation
Human Optical Axial Length and Defocus
-
The length of the eyeball can be changed by providing hyperopic defocus or myopic defocus
Myopia and Pseudo-Myopia
-
Pseudo-myopia can be cured by paralyzing the ciliary muscle
Optical reduction of peripheral hyperopic defocus
-
Reducing hyperopic defocus retards the progression of myopia
-
Outdoor activity prevents the progression of myopia
Atropine eye drops
-
Explains atropine/similar substances. They dilate the pupils and paralyze the ciliary
Blur adaptation in myopes
-
Concept of blur adaptation is given and scientific evidence of what blur adaptation does.
Eyestrain
-
Explains eye strain
-
Eye strain itself does not have any long-term complications
Pseudomyopia: Etiology, Mechanisms and Therapy
-
Psuedo-myopia is diagnosed in properly conducted eye exams because the ciliary is put to rest
-
Glasses are prescribed based on myopia / Axial elongation
Effect of Dual-Focus Soft Contact Lens Wear on Axial Myopia Progression in Children
-
Myopic defocus can help slow the progress of myopia
-
Refraining from using distance glasses to do nearsighted work helps slow the progression of myopia.
Posterior scleral reinforcement for the treatment of pathological myopia
-
Reinforcing the eyeball from the back, can be used to stop the eyeball from growing further
-
The progress of myopia is associated with the elongation of the eyeball
Axial length and choroidal thickness changes accompanying prolonged accommodation in myopes and emmetropes.
-
The eyeball changes accompanying prolonged near focusing in myopes and those with 20/20 vision
-
Possible proof that prolonged accommodation may provide the stimulus for the eyeball to elongate.
-
The eyeball grows rather than continuous strain in the muscles
Anterior scleral thickness changes with accommodation in myopes and emmetropes.
-
The thickness of the sclera changes during focusing for myopic people and people with 20/20 vision
-
Could possibly mean that the eyeball slightly changes shape during the process of focusing
Axial length changes with shifts of gaze direction in myopes and emmetropes.
-
Axial length changes with shifts in gaze direction
-
Convergence of the eyes causes pressure on the eyeball which may cause it to elongate.
-
The angle of gaze most common to book reading is the gaze that causes the eyeball to elongate the most
Theories of Accommodation
-
Different theories of accommodation of the eyeball
-
They all involve the lens in some manner
Myopia: A close look at efforts to turn back a growing problem
-
Correlation and possible causation of myopia by education
-
Physiological development of myopia in school children.
