Cheiroscope is used to test and improve binocular vision of patients suffering from Strabismus (squint) and Amblyopia (lazy eye). In order to use Cheiroscope, patients will have to use both the eyes simultaneously. The eye facing the mirror, sees the image in practice card, while the other eye sees the image s/he is sketching or colouring on a blank paper. This activity trains the brain to recognize image from both the eyes and fuse it into a single image, thereby training the patient to improve binocular vision.

The cheiroscope is a diagnostic and training machine used to assess binocular stability and alignment and to detect the presence and extent of suppression. Suppression occurs when the patient’s brain shuts off an eye by blocking its visual input when the patient loses the ability to control his eye aim or alignment. Suppression is an adaptive neurological response to protect oneself from double vision. Training on the cheiroscope gives the patient important feedback that he is suppressing and allows him an opportunity to gain the binocular control necessary to correct his eye aim and eliminate suppression.
