Visual Anatomy

This study guide covers the sensation and perception of sight, starting with the basics of light and color (wavelength, amplitude, hue, intensity). It details the eye's anatomy and the journey of light through its structures (cornea, pupil, iris, lens, retina, rods, cones, bipolar/ganglion cells, optic nerve, blind spot, optic chiasm). Key processes like transduction, accommodation, and parallel processing are explained, along with color vision theories (Young-Helmholtz Trichromatic, Opponent-Process) and common vision problems (nearsightedness, farsightedness, astigmatism). Finally, it offers exam tips and practice questions.
