The retinal reviver was designed to strengthen fusion while stimulating the retina. The reviver card may be used in a stereoscope for spelling tasks or may be used in free space for a variety of training procedures including base-in training, base-out training, rotations and spelling. In addition, red/green glasses (not included) may be used for training in free space. The retinal reviver comes complete with instructions and suggestions for training procedures.
