Viewing Stereoscopic 3D Images
Precautions on Viewing Stereoscopic 3D Images
Before viewing stereoscopic 3D images, please read this section carefully.
WARNING
Under normal conditions, viewing stereoscopic 3D images is safe for any duration that you would
normally view your screen. However, some people may experience discomfort. The following
precautions are recommended to minimize the potential for experiencing visual problems or any
adverse symptoms.
Take regular breaks, at least 5 to 15 minutes after every 30 to 60 minutes of stereoscopic 3D
viewing.
* Based on the guidelines issued by the 3D Consortium revised December 10, 2008.
Maintain an appropriate distance from the screen. Viewing from too close a distance can strain
your eyes. If you experience eye strain, immediately discontinue viewing.
If you experience any of the following symptoms during viewing:
• nausea, queasiness/dizziness, headache, blurry vision or double vision that lasts longer than few
seconds
Do not engage in any potentially hazardous activity (for example, driving a vehicle) until your
symptoms have completely gone away. If symptoms persist, discontinue use and do not resume
stereoscopic 3D viewing without discussing your symptoms with a physician.
As you get more comfortable viewing stereoscopic 3D:
• Adjust the parallax on the 3D-video playback equipment. (You may not be able to adjust the
parallax on some models of equipment.)
• Adjust the projected image to the most comfortable viewing size by zooming.
(Projecting images on the smallest or largest screen size possible may eliminate the stereoscopic
effect and strain your eyes.)
• Use the DLP
®
Link™ Invert function to properly set the video for your left and right eyes. (For
details on using “DLP
®
Link™ Invert”, see the section on its operation in this operation manual.)
The following people should limit stereoscopic 3D viewing:
– Children under 6 years of age (to protect the eye growth process)
– People with a history of photosensitivity
– People with heart disease
– People in poor health
– People who are sleep deprived
– People who are physically tired
– People under the influence of drugs or alcohol
Epilepsy
A small percentage of the population may experience epileptic seizures when viewing certain
types of images that contain fl ashing patterns of light.
IF YOU OR ANY MEMBER OF YOUR FAMILY HAS A HISTORY OF EPILEPSY
The following people should consult a physician before viewing stereoscopic 3D images.
– Anyone with a history of epilepsy, or who has a family member with a history of epilepsy
– Children under 6 years of age
– Anyone who has ever experienced epileptic seizures or sensory disturbances triggered by
fl ashing light effects
SOME LIGHT PATTERNS MAY INDUCE SEIZURES IN PERSONS WITH NO PRIOR
HISTORY OF EPILEPSY
Discontinue use if you experience any of the following symptoms while viewing stereoscopic
3D images.
– Involuntary movements, eye or muscle twitching
– Muscle cramps
– Nausea, dizziness, or queasiness
– Convulsions
– Disorientation, confusion, or loss of awareness of your surroundings
