Used to practice the function of binocular vision.
At CH-1 each eye sees a different image. A patient leans the forehead and looks thru convex lenses. One eye looks at the oblique mirror, and the other at a sheet of paper placed on the base of the device. Convex lenses create the conditions for looking in the distance, because the pictures are lying in the focus of the lens. The device is suitable for left- and right-handed children.Exercises with CH-1 Cheiroscope stimulate binocular vision, and where incomplete binocular vision occurs, they fix it and allow for a better range of depth vision.
