|
CORNEA
|
PROTECTIVE COVERING WHERE REFLECTED LIGHT IS FIRST ENTERS THE EYE
"CORN FIRST COVERS THE FIELD" |
|
|
LENS
|
BENDS LIGHT RAYS; FOCUSES A FLIPPED, INVERTED IMAGE INTO THE RETINA
"LINDSAY BENDS AND FLIPS AND IS VERY INTROVERTED" |
|
|
RETINA
|
THIN STRUCTURE AT THE BACK OF THE EYE THAT CONTAINS THE RODS AND THE CONES
"TINA IS IN THE BACK WITH RODNEY AND CONEY" |
|
|
RODS
|
CELLS IN THE PERIPHERY OF THE RETINA THAT RESPOND TO BLACK AND WHITE
BETTER IN LOW LIGHT MORE SENSITIVE TO MOTION LESS VISUAL ACUITY "RODNEY LIKES TO LAY LOW, HE'S VERY SENSITIVE, NOT THAT SHARP, DETECTS MOTION, LIKES BLACK AND WHITE" |
|
|
OPTIC NERVE
|
one of the twelve cranial nerves
behind the eyeball and transmits visual information to the brain |
|
|
BLIND SPOT
|
PLACE WHERE THE OPTIC NERVE EXITS THE EYE
HAS NO RECEPTOR CELL SO NO VISION |
|
|
LIGHT WAVES
|
ELECTROMAGNETIC WAVES THE STIMULATE RECEPTORS IN THE EYE
|
|
|
INTENSITY
|
AMOUNT OF ENERGY PER UNIT OF TIME
BRIGHTNESS |
|
|
WAVELENGTH
|
DISTANCE BETWEEN TWO WAVE CRESTS (COLOR)
refers to the distance between the peak of one wave and the peak of the next wave. |
|
|
TRICHROMATIC THEORY (YOUNG-HELMHOLTZ)
|
3 TYPES OF CONES DETECT 3 WAVELENGTHS OF LIGHT (BLUE, GREEN, RED)
DOES NOT EXPLAIN NEGATIVE AFTER IMAGES |
|
|
CONES
|
CENTERED IN THE FOVEA (MIDDLE OF THE RETINA)
RESPOND TO COLOR,GOOD FOR DAYTIME VISION MORE VISUAL ACUITY |
|
|
NEGATIVE AFTERIMAGE
|
IF YOU STARE AT ONE COLOR, THEN LOOK AT A WHITE SPACE, YOU SEE A COLOR AFTERIMAGE IN THE COMPLIMENTARY COLOR OF THE ORIGINAL COLOR
EX: YOU LOOK AT SOMETHING RED, THEN LOOK AT A WHITE SPACE AND YOU'LL SEE AN AFTERIMAGE IN GREEN |
|
|
OPPONENT PROCESS THEORY (HERING)
|
RECEPTOR CELLS ARE ARRANGED IN PAIRS
RED/GREEN BLUE/YELLOW BLACK/WHITE WHEN ONE IS STIMULATED, THE OTHER IS INHIBITED |
