PSY 3061 Lecture Notes - Lecture 10: Aqueous Humour, Binocular Vision, Binocular Disparity
Document Summary
Vision: the eye is a camera: 3 pairs of extraocular muscles direct the eye and control eyelid level. Lots of fat surrounding eyeball to protect it from trauma. Human vision (cid:862)visi(cid:271)le light(cid:863) is ele(cid:272)t(cid:396)o(cid:373)ag(cid:374)eti(cid:272) e(cid:374)e(cid:396)gy of a spe(cid:272)ifi(cid:272) (cid:449)a(cid:448)ele(cid:374)gth: wavelength of light that can affect neural cells that are responsible for signal transduction that enable vision will determine our range of vision. If pupil is more closed, less light will be allowed.

Looks like elliptical: more convex on back, can change shape, projects light onto back of eye, what ends up in back of eye is an upside down and flipped image of the actual stimulus. Light travels in a straight line unless it is bent.
