IMPORTANT SAFETY INSTRUCTIONS
Viewing 3D Imaging
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.
