A COMPLICATED PHENOMENON, HAS THE PROPERTIES OF BOTH WAVES AND PARTICLES
LIGHT
WHO FIRST PROPOSED THAT LIGHT IS TINY PACKETS OF WAVES
ALBERT EINSTEIN
WAVE PACKETS, HAVE SPECIFIC WAVELENGTHS ASSOCIATED WITH THEM
PHOTONS
BRIGHTNESS, COLOR, SATURATION
PSYCHOLOGICAL PROPERTIES OF LIGHT OR THE 3 ASPECTS OF PERCEPTION OF LIGHT
THE AMPLITUDE OF THE WAVE, HIGH OR LOW OF THE WAVE
BRIGHTNESS
HIGH WAVES
BRIGHT LIGHT
LOW WAVES
DIM LIGHT
THE LENGTH OF THE WAVE
COLOR OR HUE
MEASUREMENTS OF THE LENGTH OF THE WAVE
NANOMETERS
VISIBLE SPECTRUM: LONG WAVELENGTHS
RED
VISIBLE SPECTRUM: SHORT WAVELENGTHS
BLUE
PURITY OF THE COLOR PEOPLE PERCEIVE
SATURATION
PURE COLOR, WITHOUT A MIXTURE OF OTHER WAVELENGTHS
SATURATION
IRIS OPENING THAT CHANGES SIZE DEPENDS ON THE AMOUNT OF LIGHT IN THE ENVIRONMENT
PUPIL
MUSCLES CONTROL THE SIZE OF THE PUPIL
IRIS
CLEAR LIQUID THAT NOURISHES THE EYE
AQUEOUS HUMOR
BENDS LIGHT WAVES, THE IMAGE CAN BE FOCUSED ON THE RETINA
CORNEA
JELLY-LIKE LIQUID THAT NOURISHES AND GIVES SHAPE TO THE EYE
VITREOUS HUMOR
WHERE THE OPTIC NERVE LEAVES THE EYE; NO PHOTORECEPTOR CELLS HERE
BLIND SPOT (OPTIC DISC)
SENDS VISUAL INFORMATION TO THE BRAIN
OPTIC NERVE
CENTRAL AREA OF RETINA; GREATEST DENSITY OF PHOTORECEPTORS
FOVEA
CONTAINS PHOTORECEPTOR CELLS
RETINA
CHANGES SHAPE TO BRING OBJECTS INTO FOCUS
LENS
COVERED THE SURFACE OF THE EYE IN A CLEAR MEMBRANE
CORNEA
PROTECTS THE EYE AND FOCUSES MOST OF THE LIGHT COMING INTO THE EYE
CORNEA
HAS A FIXED CURVATURE. LIKE CAM, NO OPTION TO ADJUST THIS FOCUS
CORNEA
___ OF THE CORNEA CAN BE CHANGED (SHAPE) = VISION IMPROVING TECHNIQUES
CURVATURE
PROCEDURES TO REMOVE SMALL PORTIONS OF THE CORNEA, CHANGING ITS CURVATURE AND THUS THE FOCUS OF THE EYE
(PRK) PHOTOREACTIVE KERATECTOMY & (LASIK) LASER-ASSISTED IN SITU KERATOMILEUSIS
LIGHT FROM THE VISUAL IMAGE ENTERS THE INTERIOR OF THE EYE THROUGH A HOLE CALLED ___
PUPIL
ROUND MUSCLE OF THE EYE, COLORED PART OF THE EYE
IRIS
CAN CHANGE THE SIZE OF THE PUPIL, LETTING MORE OR LESS LIGHT IN THE EYE, HELPS THE PEOPLE FOCUS (SQUINTING)
IRIS
CLEAR STRUCTURE, BEHIND THE IRIS SUSPENDED BY MUSCLES
LENS
