There's a condition called "Alice in Wonderland syndrome" that makes you see things closer, further, bigger or smaller that is caused by abnormal amounts of electrical activity resulting in abnormal blood flow in the parts of the brain that process visual perception and texture.

Jumping spiders have binocular vision, but because their eyes are too close together, they lack parallax depth perception. Instead, they measure visual distance by how fuzzy the image becomes between the bottom and top layers of their multi-layered retina.
-
The Autokinetic Phenomenon (also referred to as autokinesis) is a phenomenon of visual perception in which a stationary, small point of light in an otherwise dark or featureless environment appears to move.
-
Blind people, who have suffered damage to the visual processing region in their brain, can still detect facial expressions. This is because conscious sight and visual perception work independently.

Ames illusion is a trick of a brain in which a room pushes the boundaries of human visual perception

About the McGurk Effect. The McGurk Effect occurs when the auditory component of one sound is paired with the visual component of another sound, leading to the perception of a third sound. And even though you know this, you can't stop it.
About a condition called prosopagnosia, also know as face blindness. A cognitive disorder of face perception where the ability to recognize familiar faces, including your own, is impaired, while other aspects of visual & intellectual functioning remain intact.
