🧪 Health Ophthalmology Simulation

This simulation explores eye diseases and visual impairments by isolating one of the most common and instructive ones: strabismus, a misalignment of the eyes caused by imbalanced extraocular muscle forces. A 3D model of both eyes shows the four rectus muscles pulling each globe, with one eye held fixating a target while the other's medial/lateral and superior/inferior muscle forces can be unbalanced to induce esotropia, exotropia, hypertropia or hypotropia. As the visual axes diverge past the fusion range, the simulation reproduces double vision (diplopia) with a live perceived-image readout in prism diopters, and lets you apply a corrective prism or run occlusion (patching) therapy and watch the resulting cortical suppression signal — the mechanism behind amblyopia — rise or fall in real time.
