Anaglyphs

Anaglyphs are filters that block out light from a portion of the target being viewed so that one part is visible by one eye and one part is visible by the other eye.

Anaglyphs (red/blue glasses) allow good control of stimulus parameters. As red filter is placed over right eye and blue over left eye, the right eye sees only red targets and left eye sees only blue targets thus viewing with both eyes simultaneously.

Conventional occlusion therapy, by patching the dominant eye to encourage stimulation of the amblyopic eye, is traditionally the mainstay treatment for amblyopia. Although effective, this simple intervention produces variable and unsatisfactory outcomes, long durations of treatment, high costs, negative psychological and emotional impacts, and poor compliance, which may even render the treatment completely ineffective.
