How the Keystone Stereoscope Works
The Keystone stereoscope operates on a simple but effective principle. It uses two slightly different images placed side by side. When viewed through the device, each eye sees a different image, and the brain combines them to create a three-dimensional effect.
This process mimics how human vision naturally perceives depth, making the experience feel realistic and immersive.
