Document Summary
What do we see: somehow a distorted and upside-down 2-d retinal image is transformed into the 3- Cornea: outermost part of the eye, 80% refraction. Lens: other 20%, reacts to how far/close we are, focuses image. Pupil: restricts amount of light, small=lets in less light(clearer image), big=more light(less clear) Ciliary muscles: help change the shape of the lens. Optic nerve: where the axons leave the eye. Blind spot: in both eyes, don"t physically see but mentally ll in the gap, we are not aware of this: 2 types of research are needed to study vision. Research probing the components of the visual system: biological mechanisms, research assessing what we see. Light enters the eye and reaches the retina: no species can see in absolute darkness but some are capable of seeing where is. Monday, october 30, 2017 little light: light can be thought of as:
