Viewing 3D Imaging - LG 47LA6900 Owner's Manual

6 IMPORTANT SAFETY INSTRUCTIONS
Viewing 3D Imaging
WARNING
Viewing Time
- When watching 3D content, take 5- 15 minute
breaks every hour. Viewing 3D content for a long
period of time may cause headache, dizziness,
fatigue or eye strain.
Some users may experience a seizure or other
abnormal symptoms when they are exposed to a
flashing light or particular pattern from 3D content.
Do not watch 3D videos if you feel nauseous,
are pregnant and/or have a chronic illness such
as epilepsy, cardiac disorder, or blood pressure
disease, etc.
3D Content is not recommended for those who
suffer from stereo blindness or stereo anomaly.
Double images or discomfort in viewing may be
experienced.
If you have strabismus (cross-eyed), amblyopia
(weak eyesight) or astigmatism, you may have
trouble sensing depth and easily feet fatigue due to
double images. It is advised to take frequent breaks
than the average adult.
If your eyesight varies between your right and left
eye, revise your eyesight prior to watching 3D
content.
Do not watch 3D content when you feel fatigue
from lack of sleep, overwork or intoxication.
CAUTION
Viewing Distance
- Maintain a distance of at least twice the screen
diagonal length when watching 3D content. If
you feel discomfort in viewing 3D content, move
further away from the TV.
Infants / Children
- Usage/Viewing 3D content for children under the
age of 5 are prohibited.
- Children under the age of 10 may overreact and
become overly excited because their vision is in
development (for example: trying to touch the
screen or trying to jump into it. Special monitoring
and extra attention is required for children watching
3D content.
- Children have greater binocular disparity of 3D
presentations than adults because the distance
between the eyes is shorter than one of adults.
Therefore they will perceive more stereoscopic
depth compared to adults for the same 3D image.
Teenagers
- Teenagers under the age of 19 may be stimulated
to light coming from 3D videos. Advise them not
to watch 3D videos for a long time when they are
tired.
Elderly
- The elderly may perceive less of a 3D effect than
the youth. Do not sit closer to the TV than the
recommended distance.
When these symptoms are experienced, stop using/
watching 3D content and get enough rest until the
symptom subsides.
- Consult your doctor when the symptoms persist.
Symptoms may include headache, eyeball
pain, dizziness, nausea, palpitation, blurriness,
discomfort, double image, visual inconvenience or
fatigue.
Only use LG 3D glasses. Otherwise, you may not
be abte to view 3D videos properly.
Do not use 3D glasses instead of your normal
glasses, sunglasses or protective goggles.
Using modified 3D glasses may cause eye strain or
image distortion.
Do not keep your 3D glasses in extremely high or
low temperatures. It will cause deformation.
The 3D glasses are fragile and are easy to
scratched. Use a soft, clean piece of cloth when
wiping the tenses. Do not scratch the lenses of the
3D glasses with sharp objects or clean/wipe them
with chemicals.
