Contrast Sensitivity Test Instructions
1
Look at the center of each circular pattern and identify the direction of the grating
2
The contrast will become progressively lower as the test continues
3
Sit 57cm (arm's length) from the screen and ensure good lighting
4
If you can't see any pattern, select "No Pattern Visible"
Important: This test uses Gabor patches to measure your contrast sensitivity function (CSF), which is crucial for night vision, reading, and detecting objects in low contrast environments.
