Free Gabor Patch Eye Training

Gabor patches — sinusoidal gratings inside a Gaussian envelope — are the stimulus used in perceptual learning research to improve contrast sensitivity and visual acuity. Clinical studies suggest 15-20 minutes of daily training over 6-8 weeks produces measurable improvements. This free session runs entirely in your browser.

Frequently Asked Questions

What is a Gabor patch and why is it used in vision therapy?

A Gabor patch is a sinusoidal grating pattern inside a Gaussian envelope that selectively stimulates neurons in the primary visual cortex (V1). It is used in perceptual learning research and vision therapy because repeated exposure to these patterns can improve contrast sensitivity and visual acuity through neural plasticity.

How does Gabor patch training improve vision?

Gabor patch training works through perceptual learning — repeated exposure to oriented grating patterns reshapes the neural response in the visual cortex. Over time, the brain becomes better at detecting contrast and discriminating fine orientation differences, which translates to improved visual clarity in everyday tasks.

How many sessions per day should I do Gabor patch training?

Research studies suggest 15 to 20 minutes of daily Gabor patch training produces measurable improvements in contrast sensitivity within 6 to 8 weeks. Consistency matters more than duration. ClearSight tracks your daily streaks and offers difficulty levels 2 through 4 for progressive training.
