IMPORTANT SAFETY INSTRUCTIONS
Viewing 3D imaging
WARNING
Viewing Environment
• Viewing Time
- When watching 3D content, take 5 to15
minute breaks every hour. Viewing 3D content
for a long period of time may cause headache,
dizziness, fatigue or eye strain.
Those who have a photosensitive seizure
or chronic illness
• 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 feel fatigue
due to double images. It is advised to take more
frequent breaks than the average adult.
• If your eyesight varies between your right and
left eye, revise your eyesight prior to watching
3D content.
Symptoms which require discontinuation
or refraining from watching 3D contents
• Do not watch 3D content when you feel fatigue
from lack of sleep, overwork, or drinking.
• 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,
eyestrain, or fatigue.
CAUTION
Viewing Environment
• 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.
Viewing Age
• Infants / Children
- Usage/ Viewing 3D content for children under
the age of 5 is recommended.
- 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 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.
Cautions when using the 3D glasses
• Make sure to use LG 3D glasses. Otherwise, you
may not be able 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 be
scratched. Always use a soft, clean piece of cloth
when wiping the lenses. Do not scratch the
lenses of the 3D glasses with sharp objects or
clean/wipe them with chemicals.
