Specification:Item Type: Vision Tester ToolMaterial: ABSRange of Training: Amblyopia, Strabismus, Simultaneous Vision and Stereopsis Purpose: Separates the visual field on both sides using a prism, a plane reflection mirror is fixed on the prism. The dominant eye gazes at the captured visual target or visual image placed on the side plate by reflecting off the plane mirror. The signal is transmitted to the opposite eye (i.e., the amblyopic eye facing the direct aperture) through the brain, and is projected onto the bottom plate. Then, catch, draw, and fuse images are trained on the bottom plate to improve vision, eliminate suppression, and establish simultaneous vision and stereopsis in patients with amblyopia or strabismus, resulting in good effects.How to Use:1. Parents draw some simple lines such as straight lines, horizontal lines, diagonal lines, and curves with black ink on a blank card, and then place it on the fixation target at the top of the side plate. 2. Place a white paper on the bottom plate and have the patient draw the lines depicted on the card, starting from easy to difficult. 3. After proficiency is achieved, different visual targets or pictures can be created for the patient to draw.packing list:1 x Stereoscope Cheiroscopes16 x Sheet of Training Card1 x Instruction Manual1 x Clip
