Today's #1 Hacker News post is a founder reflecting on selling 2,500 MIDI recorders and realizing hardware barriers are mostly perceived, not real. It reminded me of the exact same dynamic in vision therapy. For decades, dichoptic training for amblyopia required specialized clinic hardware — expensive, inaccessible, and kids hated the patching regimens. But a Meta Quest is fundamentally a dichoptic display: two OLED panels, one per eye, with independent contrast and spatial‑frequency control. That hardware alone delivers the Gabor‑pattern stimulation that research shows drives binocular plasticity.
We built AmblyoPunch around that platform: a four‑stage VR game where you punch Gabor coins, dodge red spikes, and progressively train binocular vision. No custom headset, no clinic visits — just a $300 consumer Quest. The hard part wasn’t the hardware; it was turning a clinical protocol into a game people actually want to play.
Stage 1 isolates the amblyopic eye with high‑contrast Gabor targets. Stage 2 dims the dominant eye to break inter‑ocular suppression. Stage 3 gradually restores contrast balance while increasing target speed. Stage 4 trains fusion within Panum’s area using slight image disparity, encouraging true stereopsis. Progression is performance‑gated: a rolling‑window success rate of ≥70 % unlocks the next stage, and ≥80 % is required for strabismus profiles before fusion training begins. Severity level and eye‑turn type personalize target size, speed, and stage duration for each user.
The first stage is free on the Meta Quest Store: https://www.meta.com/en-gb/experiences/amblyopunch/1239507485902689/
