IMPORTANT SAFETY INSTRUCTIONS
Viewing 3D Imaging
(For 3D models)
WARNING
Viewing Environment
y Viewing Time
- When watching 3D contents, take 5 to
15 minute breaks every hour. Viewing 3D
contents for a long period of time may cause
headache, dizziness, fatigue or eye strain.
Those that have a photosensitive seizure or
chronic illness
y Some users may experience a seizure or
other abnormal symptoms when they are
exposed to a flashing light or particular
pattern from 3D contents.
y Do not watch 3D videos if you feel nausea,
are pregnant and/ or have a chronic illness
such as epilepsy, cardiac disorder, or blood
pressure disease, etc.
y 3D Contents are not recommended to
those who suffer from stereo blindness
or stereo anomaly. Double images or
discomfort in viewing may be experienced.
y 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 frequent breaks than the
average adult.
y If your eyesight varies between your right
and left eye, revise your eyesight prior to
watching 3D contents.
Symptoms which require discontinuation or
refraining from watching 3D contents
y Do not watch 3D contents when you feel
fatigue from lack of sleep, overwork or
drinking.
y When these symptoms are experienced,
stop using/watching 3D contents 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.
CAUTION
Viewing Environment
y Viewing Distance
- Maintain a distance of at least twice the
screen diagonal length when watching 3D
contents. If you feel discomfort in viewing
3D contents, move further away from the TV.
Viewing Age
y Infants / Children
- Usage/ Viewing 3D contents 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 contents.
- 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.
y 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.
y 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
y Make sure to use LG 3D glasses.
Otherwise, you may not be able to view 3D
videos properly.
y Do not use 3D glasses instead of your
normal glasses, sunglasses or protective
goggles.
y Using modified 3D glasses may cause eye
strain or image distortion.
y Do not keep your 3D glasses in extremely
high or low temperatures. It will cause
deformation.
y 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.
