How the eye's sharp central vision and tiny eye movements work
Vision, Attention and Eye Movements at the Scale of the Foveola
This project looks at how tiny eye movements and attention shape what we see at the very center of vision, where details are sharpest.

What this research studies
If you take part, researchers will use high-resolution retinal imaging and precise video eye-tracking while you look at small targets. The team will present gaze-contingent images that move with your eyes so stimuli stay on the exact spot of the foveola and will image the packing of cone cells in that region. They will collect many brief tests to map how tiny drifts and microsaccades interact with attention and clarity at the center of vision. Combining these methods aims to overcome past technical limits and reveal how the foveola supports everyday tasks like reading and recognizing faces.
Who could benefit from this research
Good fit: Ideal candidates are adults who can sit for retinal imaging and keep steady fixation, including people with normal central vision or mild central-vision changes depending on the experiment.
Not a fit: People with very poor central vision who cannot fix their gaze, young children, or anyone unable to complete in-person imaging sessions may not be able to participate or directly benefit.
Why it matters
Potential benefit: If successful, the work could improve diagnosis and guide therapies, devices, or training to protect or restore sharp central vision.
How similar studies have performed: High-resolution retinal imaging and gaze-contingent eye-tracking have been used successfully in other vision research, but combining them to study the foveola at this fine scale is relatively new.
