Targeted visual training to improve sight in amblyopia and age-related vision loss
Systematic Psychophysical Investigation of Visual Learning
Looks at whether training different stages of visual brain processing can improve everyday sight for people with amblyopia or declining vision.

What this research studies
You would practice visual tasks using simple patterns (like Gabor patches) and natural scenes while researchers measure your performance and record brain activity (EEG). The team compares training that emphasizes early feedforward processing versus later recurrent processing to see which leads to improvements that are specific to the trained features or that generalize to untrained tasks. Sessions involve repeated visual practice and brain recordings to track how learning changes perception and neural signals over time. The ultimate aim is to design training that transfers to real-world vision and could be used in rehabilitation.
Who could benefit from this research
Good fit: Ideal candidates are people with amblyopia or mild-to-moderate visual decline who can attend repeated lab sessions and participate in visual training and EEG recordings.
Not a fit: People with severe, irreversible structural eye damage or those unable to perform visual tasks or tolerate EEG are unlikely to benefit from this training.
Why it matters
Potential benefit: If successful, this work could produce new vision-training programs that improve clarity and day-to-day visual function for people with amblyopia or mild-to-moderate vision deterioration.
How similar studies have performed: Previous perceptual learning research has shown meaningful improvements for some patients, but transferring gains to everyday vision remains limited and this project aims to clarify why.
