Vintage Optometry Stereoscope Cards Set of 10 | Antique Vision Therapy Stereoviews | Medical Ephemera for Holmes or Brewster Stereoscope

Fascinating set of 10 antique stereoscope cards originally created for optometry and vision therapy use. These stereoview cards were designed to be viewed through a stereoscope such as a Holmes or Brewster stereoscope to help patients develop binocular vision, improve depth perception, and assist in treatment for conditions including strabismus and amblyopia. A wonderful piece of early medical history and visual science, these cards make an excellent addition to collections of antique medical instruments, ophthalmology memorabilia, optical devices, or Victorian/early 20th century ephemera. The cards feature paired photographic or printed images intended to merge into a single 3D image when viewed through a stereoscope. Originally used in professional vision training and therapeutic exercises.
