You may experience discomfort while watching 3D content. You may feel symptoms of eye strain, vision
fatigue, color or depth distortion, motion sickness, nausea, dizziness, disorientation, or other discomforts.
If you experience any of these symptoms, stop watching and take a break for at least thirty minutes before
resuming. If the symptoms are severe or continue even after you have stopped watching 3D content,
consult a doctor.
Take care to monitor children's watching of 3D content. Children (including teenagers) may be more at
risk of experiencing discomfort while watching 3D content and less likely to report symptoms. Monitor
children's 3D content viewing and watch for signs of discomfort.
Some viewers may be susceptible to epileptic seizures or strokes when viewing 3D images, even if those
conditions have not been previously diagnosed. If you or anyone in your family has a history of seizures or
strokes, or if you have any other reason to think you or someone under your supervision may be susceptible
to epileptic seizures or strokes, consult a doctor before watching 3D content.
Even if you do not experience any of the above symptoms, take regular breaks from watching 3D
content.
