Visual Stimulus Light Waves From Visible Spectrum Spectral Colors: Red, Orange, Yellow, Green, Blue, Indigo, Violet

This document discusses the process of vision. Light waves from the visible spectrum enter the eye and are focused on the retina by the cornea and lens. The retina contains two types of photoreceptor cells, rods and cones, which detect light and send signals through the optic nerve to the brain where an image is formed. Rods function in low light and cones provide color vision and clear central vision through the fovea.

1ST SLIDE

Visual Stimulus

 Light waves from visible spectrum


 Spectral colors: red, orange, yellow, green, blue, indigo, violet
2ND SLIDE

Visual Receptor
 Eye is the sense organ for vision

 Cornea – clear structure that covers and protects the eye, focuses light on retina
 Iris – gives the eye its color
 Pupil – regulates amount of light that enters the eye
 Lens – enables refraction of light rays, changes shape to bring objects into focus
 Fovea – central area of retina, point of clearest vision
 Optic nerve – sends visual information to the brain

3RD SLIDE

Cones – day receptors


Rods – night receptors
