This set of 101 charts for use in the stereoscope is similar to the Wells series. The chief point of difference is that some of the charts used for developing dormant vision have safety movie films mounted on disks. When one of these charts is held toward the light the film is illuminated. The charts for developing macular visual function are printed on both sides so that they may be used for training either eye. All the charts are brightly colored. Those for developing fusion and stereopsis are not up to the standard of the corresponding ones in other sets. The chief advantage of these charts is that they offer a variety of designs for young children. They may be used to supplement the Wells charts.
