Скачать или смотреть Color blindness test - CAD test - medium level

This is medium difficulty level of CAD vision test which detects mild and moderate forms of red/green and blue/yellow color vision deficiencies.

For most accurate results, increase the brightness of your screen and do the test in a dark room. Your screen colors must be on default so double check that you accidentally don't have any color filter activated on your device. If you want to rule out any possible impact of screen colors irregularity to your result, you should watch the video on two completely different screens. Don't forget to watch the video in highest resolution (720p).

If the colored square starts blurring into the background and you become unable to follow it, even for just a short period of time, you failed the test. If you still fully pass the easy level of the test, then your deficiency is in the mild-moderate severity range and is definitely NOT strong.

To people with normal vision, the colored square should be approximately visible with the same intensity throughout the whole video.
