Viewing Environment
Viewing Distance
y
- 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
y
- Usage/ Viewing 3D content for children under the age of 5 is 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.

- Advise teenagers under the age of 19 not to watch 3D videos for a long time when they are
tired.
Elderly
y
- The elderly may perceive less of a 3D effect than the youth. Do not sit closer to the TV than
the recommended distance.
