Peripheral Vision Test Image (IMAGE) University College London 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 middle 'C' in every triplet. Is the gap facing left or right? You may find it easier to read in some directions than others. People usually find it easier to read below the dot than above, and easier still to the left or right.
