Stereoscopic images are visual representations that create the illusion of depth by presenting two slightly different perspectives of the same scene. These images are designed to be viewed with both eyes, allowing the brain to combine the two views into a single three-dimensional perception. This technique is commonly used in 3D movies and virtual reality experiences. To view stereoscopic images, special glasses or devices may be required, which help filter the images for each eye. The concept dates back to the 19th century and has evolved with technology, influencing fields such as photography, cinema, and virtual reality.
