How attention can change eye suppression in amblyopia (lazy eye)
Interocular Suppression and Selective Attention in Amblyopia
This project tests whether directing attention to the weaker eye can reduce visual suppression for adults with amblyopia (lazy eye).

What this research studies
If you join, you'll do short vision tasks where each eye sees different images while researchers cue you to focus on one eye or the other. They will record what you report seeing and measure brain activity with EEG while the two eyes compete for perception. Some tests will also boost the weaker eye's contrast to compare effects of attention versus stronger visual input. The team will compare behavioral reports and brain signals to see how attention changes suppression of the amblyopic eye.
Who could benefit from this research
Good fit: Ideal participants are adults with amblyopia (lazy eye), including those with anisometropia or strabismus, who can attend lab visits and follow brief visual tasks.
Not a fit: Children under 18 and people with severe eye disease or very poor vision that prevents completing the visual tasks are unlikely to be eligible or to benefit directly.
Why it matters
Potential benefit: If successful, this work could point to attention-based strategies that help reduce suppression and improve vision in people with amblyopia.
How similar studies have performed: Prior lab studies of attention, binocular rivalry, and contrast manipulation have produced temporary shifts in eye dominance, but lasting clinical improvements remain experimental.
