6 IMPORTANT SAFETY INSTRUCTIONS
Viewing 3D Imaging
WARNING
Viewing Environment
y 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.
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 content.
y 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.
y 3D Content is not recommended for 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 more frequent breaks
than the average adult.
y 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 content
y Do not watch 3D content when you feel
fatigue from lack of sleep, overwork, or
intoxication.
y 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.
CAUTION
Viewing Environment
y 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
y 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.
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 Only 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
scratched. 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.
