How Humans Learn to See




Karpathy's Pelican owns HN right now (567 pts, 388 comments). The thread's obsessed with how machines learn to see. Meanwhile, human vision is *also* a trainable system — and we built a VR game that exploits that. AmblyoPunch on Meta Quest: punch Gabor-pattern coins (vision-science stimuli used to drive cortical contrast and orientation processing), dodge red spikes, and progress through a four-stage dichoptic plan that teaches both eyes to work together. Stage 1 warms up the lazy eye monocularly. Stage 2 dims the dominant eye to break suppression. Stage 3 rebalances brightness so the lazy eye stays engaged. Stage 4 trains fusion via slight disparity within Panum's area. Personalize for lazy eye (L/R), severity (Mild/Moderate/Severe), and strabismus type. Performance-gated advancement (≥70% rolling success). No patch. No drills. Just play. 👉 https://www.meta.com/en-gb/experiences/amblyopunch/1239507485902689/

London Schools Are Using VR to Treat the Brain. Could Lazy Eye Be Next?

  # London Schools Are Using VR to Treat the Brain. Could Lazy Eye Be Next? Fifteen secondary schools in Sutton, London, have started deploying virtual reality headsets — not for gaming, not for novelty, but as a mental health intervention. In partnership with an NHS mental health trust and VR firm Phase Space, students are using immersive environments to manage exam stress, ADHD symptoms, and anxiety from difficult home situations. This pilot matters beyond its immediate goal. It signals that VR has crossed a threshold: institutions are now treating it as a legitimate therapeutic tool, not experimental tech. ## The brain, not the device What makes VR compelling for mental health is the same thing that makes it compelling for neurological conditions: presence. When you're in a headset, your brain accepts the environment as real enough to respond. Heart rate changes. Stress hormones shift. Neural pathways engage. That same mechanism — the brain treating virtual stimuli as genuine in...

Attention under pressure

  Hannah Natanson spent months fighting to protect her sources after the FBI raided her home. On Monday, she won a Pulitzer Prize. The story is a masterclass in something we rarely discuss: attention under pressure. Investigative journalism demands an extraordinary kind of visual and cognitive endurance. Hours of document review. Spotting patterns across thousands of pages. Maintaining focus when the stakes — and the stress — are sky-high. Most of us aren't facing federal subpoenas. But many of us are facing something quieter: visual coordination challenges that make sustained attention feel like a battle. For individuals with amblyopia — commonly known as lazy eye — the brain has learned to favour one eye over the other, compromising depth perception and binocular vision. Everyday tasks like reading or screen work become an uphill climb. That's where Amblyotube comes in. Developed by Seven Sportz, it's a Meta Quest app that delivers a different visual experience to each ey...

London schools are trialling VR for student mental health — the NHS is backing it. Could this same approach treat lazy eye?**

  Amblyotube on Meta Quest Store Saw this piece about 15 London secondary schools using VR headsets (Phase Space) in partnership with an NHS mental health trust to help pupils with exam stress, ADHD, and anxiety. It got me thinking: if VR is becoming accepted as a therapeutic tool for the brain, what about vision conditions that rely on neuroplasticity? Amblyopia (lazy eye) affects about 3% of kids. Traditional treatment is patching the stronger eye, but compliance is poor — kids hate wearing a patch — and it doesn't directly train binocular vision. Patching isolates the weaker eye without teaching both eyes to work as a team. There's a Meta Quest app called **Amblyotube** (developed by Seven Sports) that takes a different approach. It uses **dichoptic vision training**: each eye sees a slightly different visual feed while you watch YouTube-style content. Here’s how it works: - **Dominant Eye Shader**: Applies adjustable blur, contrast, brightness, and opacity to the stronger e...
