Document Summary

In case your eyes are pointed a different direction than your body! An object in the visual field produces an inverted image on the retina. The optic nerve exits the eyeball on the nasal side (the side closer to the nose). Iris: pupil, cornea, lens, ciliary muscle, rods and cones, fovea, blind spot: the optic nerve fibers group together and exit through the back of the retina, in the blind spot of the eye, optic nerve, retina. Bipolar cells, located closer to the center of the eye. Color vision: visible light is a portion of the electromagnetic spectrum, the perception of color is dependent upon the wavelength of the light, humans perceive wavelengths between 400 and 700 nanometers (nm) Visible wavelengths are dependent upon the species" receptors. Specificity of color vision: depends on specific receptors within the eye, two major interpretations of color vision, trichromatic theory/young-helmholtz theory, opponent-process theory.
