Bereik en inhoud
Item is a green wood and plastic Correct-Eye-Scope used for vision testing and vision therapy. Item comes with a green wooden base and metal plates designed to hold Correct-Eye-Graphs or stereoscopic like drawings manufactured by Keystone Viewing Company to improve or test vision. A correct-Eye-Graph template would be placed in the sliding card holder, next the user would view the template through the stereoscope and attempt to trace the image displayed. This item comes with two booklets; one booklet designed for the left eye and one booklet designed for the right eye. Booklets are marked as such. Booklets also contain user instructions. The stereoscope is made from a wooden base with metal hooded eye holder similar to the design of a Homles stereoscope.
