28 evidence-based exercises
Brock String
Uses physiological diplopia to develop voluntary vergence control and binocular fusion at multiple depths simultaneously. A clinical staple since the 1950s.
Jump Vergence
Builds vergence facility — speed and accuracy of switching between near and far fixation. RCT-proven to reduce CI symptoms within 12 weeks.
Vergence Facility
Trains the speed of convergence/divergence responses — the key clinical measure in the CITT-ART protocol. Normal is 15+ cycles/min with 12ΔBO/3ΔBI prisms.
Barrel Card
Builds positive fusional vergence amplitude — the amount of base-out prism the eyes can overcome. A direct measure and treatment target in every CI protocol.
Aperture Rule
Classic orthoptic instrument. Septum separates images so each eye sees one half — forces binocular fusion at controlled vergence demands. Builds both convergence and divergence ranges.
Divergence Training
Trains negative fusional vergence — the ability to diverge. Often neglected in CI-focused programmes. Essential for patients with convergence excess or divergence insufficiency.
Accommodative Facility
Binocular ±2D flipper training — the standard CITT-ART protocol. Normal BAF = 8 cycles/min. Improves accommodative amplitude and facility together.
Monocular Acc. Facility
Each eye trained separately with ±2D flippers. Research (PMC 2014) shows monocular and vergence exercises produce additive improvement when kept separate.
Hart Chart
Near chart letter → far target → back. Trains rapid accommodative shifts under real reading conditions. Directly reduces screen-induced eye strain.
Near-Far Focus
Simple but effective: repeated near-far focus transitions reduce accommodative lag and asthenopia symptoms. Particularly beneficial for digital screen users.
Smooth Pursuit
Trains smooth, continuous eye tracking. Essential for reading, driving, and sports. Directly measurable improvement in horizontal and vertical gain.
Saccade Training
Trains rapid, accurate eye jumps — the fundamental movement used in reading. Improves both latency and accuracy of saccades.
DEM Saccadic Tracking
Based on the Developmental Eye Movement (DEM) test — the paediatric orthoptic gold-standard. Builds automatic, rhythmic saccadic patterns for fluent reading.
Reading Saccades
Trains the precise left-to-right scan pattern required for efficient reading. Reduces regression saccades and word-skipping.
Marsden Ball
Standard in orthoptic and sports vision clinics. Trains dynamic smooth pursuit and voluntary convergence against a moving 3D target. Excellent for post-concussion rehabilitation.
Zig-Zag Pursuit
Challenges pursuit along diagonal and oblique paths — harder and less trained than horizontal. Important for sports and complex visual environments.
Dichoptic Training
Based on AAO 2024 dichoptic therapy. Each eye sees different letters through red/green filters — task only solvable binocularly. Directly targets interocular suppression.
Worth 4-Dot
Universal clinical standard for detecting and monitoring monocular suppression. Training with W4D reinforces binocular awareness and is used in every strabismus / amblyopia programme.
Red-Green Bar Reader
A classic orthoptic anti-suppression tool. Alternating red/green filters require both eyes to contribute — the patient cannot read the full text with one eye suppressed.
Patching / Penalisation Log
Occlusion therapy remains the first-line treatment for amblyopia in children under 8. This tool allows the optometrist to log prescribed patching hours and monitor compliance.
Monocular Fixation Training
Trains the amblyopic eye to use central (foveal) fixation while the fellow eye is occluded. Critical first step before binocular amblyopia therapy.
Random Dot Stereogram
Gold-standard binocular fusion tool — cannot be solved monocularly. Used in CVS2 clinical vergence programmes. Builds and measures stereoacuity directly.
Contrast Sensitivity
Perceptual learning studies (Zhang et al. 2014) show up to 28% improvement in amblyopic eye visual acuity after contrast discrimination training. Targets V1 cortical plasticity.
Fixation Stability
Trains steady, accurate central fixation. Critical for amblyopia patients with eccentric fixation, and for patients with mild nystagmus building fixation stability.
Reaction Time Trainer
Visual reaction time is the most trainable component of athletic reaction. Research shows 15-25% improvement in RT after 4 weeks of daily practice. Critical for batting, tennis, and combat sports.
Peripheral Awareness
Peripheral vision processing is essential in team sports for court/field awareness. Training expands the useful field of view and improves detection of peripheral movement.
The Swarm — Multi-Object Tracking
Multiple Object Tracking (MOT) tasks mirror the demands of team sports — tracking multiple moving players simultaneously. Evidence shows significant improvements in dynamic visual attention with MOT training.
Hand-Eye Tracking
Trains the visuomotor integration loop — the time between seeing a target and responding to it with a hand movement. Directly translates to catching, batting, and ball-sport performance.
