Document Summary
Light: conceptualized as a wave or stream of photons o o o o o absorbed scattered reflected transmitted refracted. Cone: for daylight vision, fine visual activity, color o o o s-cones: short wavelength-sensitive, blue l-cones: long wavelength-sensitive, red m-cones: medium wavelength-sensitive, green. Duplex retinas: containing both rods and cones. Fovea: high concentration of cones, no rods, highest visual acuity. Eccentricity: distance btw retinal image and fovea o focusing light to the retina emmetropia: normal vision diopter: unit of measurement of the optic power of a lens, reciprocal of focal length. Diffuse bipolar cell: processes spread out to receive input from multiple cones. Midget bipolar cell: small bipolar cell in central retinal that receives input from a single cone. On bipolar cell: responds to an increase n light captured by cones. 2 intermediate neutron types (bipolar & amacrine cells) and transmits info to the brain and midbrain.
