These reversible Red/Green Anaglyph Glasses have a durable metal frame and spring-loaded temples. Storage case included.

Anaglyph red/green glasses are used to separate two overlapping images—one tinted red and the other green—so that each eye sees only one of the images. This creates a binocular disparity (difference in images between the two eyes), which the brain interprets as depth. They are primarily used for stereopsis testing (measuring depth perception) and certain binocular vision assessments.
