Using brief flickering light to boost vision and attention
Noninvasive modulation of perception and cognition with flicker induced response modulation.
This project tests whether short sessions of gentle flickering light can strengthen brain responses to improve sight, attention, and visual memory for people with amblyopia, age‑related decline, or other vision problems.

What this research studies
You would sit for short sessions watching simple flickering screens while researchers record brain activity with EEG and run vision and attention tests. The team will look for lasting boosts in neural signals and then check whether those boosts lead to better visual detection, sharper acuity, improved contrast sensitivity, spatial attention, or stronger visual working memory. The work builds on animal and early human pilot data that showed neural and behavioral gains after repetitive visual stimulation. If changes are seen, they will test how long benefits last and whether effects generalize beyond the exact patterns shown.
Who could benefit from this research
Good fit: Ideal participants include people with amblyopia or reduced visual acuity/contrast sensitivity, older adults with visual or attention complaints, and healthy volunteers interested in improving visual performance.
Not a fit: People whose vision loss is caused by advanced structural eye disease, those with severe neurological impairment, or individuals with photosensitive epilepsy may not benefit and could be excluded for safety.
Why it matters
Potential benefit: If successful, this could become a simple, noninvasive way to improve vision and visual thinking for people with amblyopia, low vision, or age‑related visual problems.
How similar studies have performed: Prior animal studies and small human pilots have shown that repetitive visual stimulation can boost neural responses and produce short‑term vision gains, but broad generalization beyond specific patterns is limited and this flicker approach is relatively new.
