Gamified optical prototype for adaptive binocular vision enhancement

Prolonged near-work in digital environments frequently contributes to Computer Vision Syndrome, impairing binocular vision and highlighting the clinical need for orthoptic interventions. This study introduces a novel automated headmounted opto-mechanical prototype for gamified binocular vision training and evaluates its functional efficacy. The device features Bluetooth-synchronized dual DC motors for rapid ±2.00 D spherical lens commutation, alongside interchangeable chromatic filters to control binocular dissociation. Twenty-three healthy adults completed a structured 11-session training protocol utilizing three interactive software modules to stimulate accommodative facility, vergence facility, and fusional reserves, with the latter two employing Random Dot Stereograms (RDS). Post-training clinical assessments revealed statistically significant improvements in both monocular and binocular accommodative facility, increasing to 16 cycles per minute (p < 0.05). Notably, while baseline clinical motor fusional reserves were adequate, initial sensory fusion in the RDS software broke at low optical loads (8 prism diopters), which subsequently doubled to 16 prism diopters following the intervention. These findings demonstrate the prototype's clinical viability and its specific capacity to enhance sensory-motor integration, offering a quantifiable, data-driven alternative to traditional manual vision therapy.
