Adult lazy eye may be trainable: brain plasticity under the microscope

NCT ID NCT07764198

First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time

Summary

This study tests whether a home-based computer program, called Gabor-based perceptual learning, can improve vision in adults with amblyopia (lazy eye). Participants aged 18-39 will be randomly assigned to either start training immediately or after a 12-week delay, with all receiving the same 12-week training. The training involves repeated visual tasks on a calibrated screen, designed to exercise eye-brain coordination. The goal is to see if this non-invasive approach can boost visual acuity and other visual functions in adulthood.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Gabor-based perceptual learning using RevitalVision software
What this could lead to
If effective, this could offer a non-invasive, home-based treatment to improve vision in adults with amblyopia, challenging the belief that lazy eye is untreatable after childhood.
What could go wrong
The trial is relatively small and early, and results may not apply to all types of amblyopia. Training requires dedication and may cause temporary eye strain or headaches.
