Those with monocular vision (vision only in one eye) lack strong eye depth perception. Kaur S, Jain S, Sodhi HB, Rastogi A, Kamlesh. Let’s take a closer look: How do we actually perceive the size of objects? Using kinetic depth perception enables the brain to calculate time-to-crash (aka time-to … Though this sounds silly in itself to ask, I would still ask it. The most common reasons for stereo-blindness are: Medical disorders that prevent the eyes focusing and/or aligning correctly (e.g. For example, it is easy to recognize that an image is a photo, since cameras do not have accurate depth perception.

Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. If you are unable to see the 3D effect at all, you may be stereo-blind, otherwise referred to as having monocular vision, being a flat-viewer or lacking depth perception.
