| Question | Answer |
|---|---|
| cornea | the transparent protective coating over the front part of the eye |
| pupil | a small opening in the iris through which light enters the eye |
| iris | the colored part of the eye that regulates the size of the pupil |
| lens | the transparent part of the eye inside the pupil that focuses light onto the retina |
| retina | the lining of the eye containing receptor cells |
| cones | receptor cells in the retina responsible for color vision |
| rods | receptor cells in the retina responsible for night vision and perception of brightness |
| fovea | the area of the retina that is the center of the visual field |
| optic nerve | the bundle of axons of ganglion cells that carries neural messages from each eye to the brain |
| blind spot | the place on the retina where the axons of all the ganglion cells leave the eye and where there are no receptors |
| light | the small segment of the electromagnetic spectrum to which out eye are sensitive |
| wave lengths | the different energies represented in the electromagnetic spectrum |
| hues | the aspects of color that correspond to names such as red green or blue |
| brightness | the nearness of a color to white as opposed to black |
| saturation | the vividness or richness of a hue |
| visual activity | the ability to distinguish fine details visually |
| nearsightedness | a condition which the visual image entering our eye is focused slightly in front of our retina rather than directly on it |
| farsightedness | a condition in which the visual image entering our eye is focused behind rather than directly on the retina |
| subtractive color mixing | the process of mixing pigments each of which absorbs some wavelengths of light and reflects others |
| additive color mixing | the process of mixing lights of different wavelengths to create new hues |
| trichromatic theory | the theory of color vision that holds that all color perception derives from three different color receptors in the retina |
| opponent process theory | theory of color vision that hold that three sets of color receptors respond to determine the color you experience |
| color blindness | partial or total inability to perceive hues |
| feature detectors | specialized brain cells that only respond to particular elements in the visual field such as movement or line of specific orientation |
| monocular cues | visual cues requiring the use of one eye |
| auto kinetic illusion | the perceived motion created by the absence of visual cues surrounding a single stationary object |
| stroboscopic motion | the apparent motion created by a rapid series of still images |
| phi phenomenon | apparent movement caused by flashing lights in sequence |
