Our eye detects only a narrow band of electromagnetic energy ROYGBIV Shortest:VIOLET Longest: RED Electromagnetic Spectrum
Light passes through the cornea, pupil, and lens, before being focused on the retina, and activating the photoreceptors (receptor cells for light), rods and cones The human eye
Process of adjusting the lens to bring an image accomodation
high acuity in good lighting; color vision cones
high sensitivity, allowing for low-acuity vision in dim light; movement rods
change in the form of energy and the beginning of neural signaling transduction
Photoreceptors>bipolar cells> ganglion cells retina
axon leaves retina blind spot
center of the retina, higher acuity, mostly cones fovea
