About ByEye
ByEye is a small collection of tests that check how accurately you can judge things by feel, without a ruler or a clock. There is no sign-up, every test runs in your browser, and your results stay in that browser.
The scoring method for each test is explained below it. These are tools for fun and practice, not medical assessments. The site is supported by ads.
