45. DIGITAL 3D ADVANCES IN DIGITAL PHOTOGRAPHY AND STEREOSCOPY HAVE
ENABLED FILMMAKERS TO AFFORDABLY PRODUCE 3D FILMS AND
THEATRE OWNERS TO AFFORDABLY SHOW THEM.
A 3D DIGITAL CAMERA RECORDS
VIDEO, CIRCULARLY POLARIZING THE
RIGHT VIEWPOINT USING RIGHT-
HANDED POLARIZATION...
...WHILE RECORDING THE LEFT
VIEWPOINT USING LEFT-HANDED
CIRCULAR POLARIZATION.
BOTH IMAGES ARE PROJECTED
SIMULTANEOUSLY ONTO THE THEATRE
SCREEN, IN A MANNER THAT
GUARANTEES THAT THE VIEWPOINTS
ARE SYNCHRONIZED.
THE MOVIEGOER WEARS POLARIZED
GLASSES THAT ONLY ALLOW THE RIGHT-
HANDED POLARIZED IMAGES TO PASS
THROUGH THE RIGHT LENS AND THE LEFT-
HANDED POLARIZED IMAGES TO PASS
THROUGH THE LEFT LENS.

46. VERGENCE VS. ACCOMMODATION
PROJECTING 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
THIS RESULTS IN
SERIOUS EYESTRAIN
AND HEADACHES FOR
