Stereoscopes

A stereoscope is a device that allows us to view two slightly different images of the same scene simultaneously, mimicking our natural binocular vision. By presenting each eye with its own image through lenses or mirrors, the brain combines these perspectives to create a single, three-dimensional (3D) perception. This enhances the sense of depth and realism in photographs or images. Stereoscopes were popular in the 19th and early 20th centuries for entertainment and education, offering immersive viewing experiences of landscapes, cityscapes, and other scenes.
