VERGENCE VS. ACCOMMODATIONPROJECTING A 3D IMAGE ONTO A 2D
SCREEN OR TELEVISION DISPLAY
TENDS TO PLAY TRICKS WITH ONE’S
VISUAL PERCEPTION.IN THE REAL WORLD, WHEN A PERSON
TRIES TO FOCUS ON A DISTANT OBJECT,
THE EYES EXPERIENCE VERGENCE, WHERE
THEY BOTH ROTATE ON THEIR OWN
VERTICAL AXES UNTIL THEY BOTH POINT
AT THE OBJECT.MEANWHILE, THE EYES EXPERIENCE
ACCOMMODATION, WHERE THEY
REFLEXIVELY FOCUS ON THE OBJECT IN
ITS DISTANT POSITION, CAUSING
NEARBY OBJECTS TO GO OUT OF
FOCUS.WITH 3D IMAGES, HOWEVER, THE EYES
ROTATE SO THEY ARE POINTED TO
WHERE THE OBJECT SEEMS TO BE, BUT
THE REFLEXIVE FOCUS MUST ADJUST TO
THE SCREEN’S ACTUAL LOCATION,
ELIMINATING THE NATURAL BLURRING
OF NEARBY OBJECTS.
THIS RESULTS IN
SERIOUS EYESTRAIN
AND HEADACHES FOR
MANY 3D AUDIENCE
MEMBERS.
