Eye-Movement Glasses (Feb, 1954)
An extra pair of eyes seems to sprout beneath the cheekbones of a person using a new visual aid. The effect comes from inclined transparent mirrors attached to a pair of glassless spectacles. With the tool an observer can watch a reader’s eye movements and discover the reasons for retarded reading rate or comprehension. It is possible to estimate the length and number of eye pauses, the number of backward eye movements, and the smoothness of eye movement rhythm.
