Health precautions to users viewing 3D images
Before viewing, be sure to read health care precautions that may be found in the user's manual included with your 3D
eyeglasses or your 3D compatible content such as Blu-ray Discs, video games, computer's video files and the like.
To avoid any adverse symptoms, heed the following:
• Do not use 3D eyeglasses for viewing any material other than 3D images.
• Allow a distance of 2 m/7 feet or greater between the screen and a user. Viewing 3D images from too close a
distance can strain your eyes.
• Avoid viewing 3D images for a prolonged period of time. Take a break of 15 minutes or longer after every hour
of viewing.
• If you or any member of your family has a history of light-sensitive seizures, consult a doctor before viewing 3D
images.
• While viewing 3D images, if you get sick such as nausea, dizziness, queasiness, headache, eyestrain, blurry
vision, convulsions, and numbness, stop viewing them. If symptoms still persist, consult a doctor.
• View 3D images from the front of the screen. Viewing from an angle may cause fatigue or eyestrain.
