Who invented 3d glasses

This way, the photographs mimic what each one of our two eyes would see in reality. This method is far from ideal, however. It requires people to "cross" their eyes, which some people cannot do or find uncomfortable. In the late 19th and early 20th century, the stereoscope was invented to address these issues. The stereoscope used lenses that merged the two distinct images into one, giving the effect of a 3D scene without straining the eyes.

The stereoscope was a popular novelty in bars and arcades until around the s, when film became the dominant media for entertainment.

Surprisingly, even today most people are probably familiar with the technology. The View-Master, a ubiquitous childhood toy for over 65 years, is a version of the stereoscope. SI's latest Swimsuit Edition features anaglyph images. They remain popular largely because of their low cost. Image courtesy of SI. When most people hear the term '3D,' they don't think of stereoscopes or View-Masters.

Instead, flimsy plastic glasses with red and blue lenses usually come to mind. These glasses, when used with special photographs called anaglyph images, create the illusion of depth. Traditionally, anaglyph images were taken using two slightly separated cameras, one with a red filter and one with a blue filter.

Recently, the filtering is being done afterwards with a processing program like Adobe Photoshop. In both cases, the images are then combined to form a single picture, or anaglyph image.

When viewed without 3D glasses, these images will look blurry and discolored. Using a red and blue lens 'tricks' the brain into seeing a 3D image. Each eye sees a slightly different image. The eye covered by the red lens will perceive red as "white" and blue as "black," and vice versa for the other eye. This disparity mimics what each eye would see in reality, as with most 3D technology. Because the traditional red-blue glasses are inexpensive to produce, anaglyph images remain popular in modern media.
