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 LCD shutter eyeglasses or your 3D compatible content such as DVDs, video games,
computer's video files and the like.
To avoid any adverse symptoms, heed the following:
- Do not use LCD shutter 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.
