The science
Vision training is one of the better-studied corners of ophthalmic care. Below are the peer-reviewed studies that shaped the Unblur program — what we use, what they actually claim, and where the limits are.
CITT Study Group, Archives of Ophthalmology · 2008
The randomized clinical trial that established vergence therapy as the gold standard for convergence insufficiency in adults. Forms the backbone of Unblur's focus-flexibility track.
Camilleri et al., Vision Research · 2014
Demonstrated that targeted contrast-sensitivity training produces measurable improvements in adult myopes, contradicting the long-held belief that vision is fixed in adulthood.
Erickson et al., Optometry · 2011
Six weeks of structured peripheral-awareness and saccadic-tracking drills produced significant gains in trained athletes versus controls. The basis for Unblur's peripheral track.
Rosenfield, Ophthalmic & Physiological Optics · 2011
Comprehensive review identifying ciliary muscle fatigue and reduced blink rate as primary drivers of digital eye strain. Supports the case for daily focal-flexibility practice in screen-heavy lives.
Karmarkar & Dan, Neuron · 2006
Foundational neuroscience review showing that visual processing remains adaptable in adulthood — the biological premise that makes any vision training program possible.
Powell et al., Journal of Behavioral Optometry · 2013
Six weeks of saccadic training improved reading speed and tracking accuracy in adults with no diagnosed vision disorder. Influences our tracking exercises.
