Binocular depth cues
Binocular depth cues refer to how the eyes perceive visual information. Images interpreted using this method are seen with two eyes.
o Retinal disparity refers to the slight difference in the location of the images in the retina, which are being perceived. The difference between the two retinal images provides the individual with information about the location and distance of the object being perceived.
o Convergence refers to how the brain detects distance from a designated object when there is tension on the eye muscle. The nearer the object, the greater the eye muscle tension is.

Monocular depth cues
Monocular depth cues require the use of one eye to perceive visual information. This provides the brain with information about the distance of an object from a person (who is perceiving the object).
o Accommodation refers to the automatic focusing mechanics in the lens on an eye, which can change bulge and flatted to perceive visual information from different distances.
o Pictorial depth cues refer to the linear perspective, interposition, texture gradient, relative size and height in the visual field, which function tohelp to portray image depth.
- Linear perspective is the merging of parallel lines as they withdraw into the far distance.
- Interposition occurs when an image is obscured by another and the front image is perceived to be closer in distance.
- Texture gradient refers to the dulling detail of an image is it moves into the distance.
- Relative size refers to the way an individual perceives an object which is produced as the largest image on the retina and is perceived as closest.
- Height in the visual fields refers to the location of an image or object in the area of our visual field.
