Peripheral Vision Test Image: Clocks up and Down (image) University College London Share Print E-Mail Caption This is an image to demonstrate visual 'crowding' and test peripheral vision. Ensure that the red dot in the centre of the image is at eye level and focus on it. While holding your focus on the red dot, try to read the time on the middle clocks above and below the dot. Most people find it easier to read below rather than above.
