Information for your safety and
comfort
The content in this guide supplements the safety and comfort information
contained in the user documentation that came with your computer.
Safety requirements
Do not wear the wireless glasses in any situation that requires normal visual
perception. Do not use the glasses as sunglasses.
Under normal conditions, stereoscopic 3D viewing is safe for any duration that
you would usually view your display. However, some people may experience
discomfort. To minimize the potential for experiencing visual problems or any
adverse symptoms:
• Take the stereoscopic 3D medical test to verify your ability so see
stereoscopic 3D images.
• Maintain a distance no closer than 2 to 2.5 feet away from the display.
Viewing from too close a distance can strain your eyes.
• Take regular breaks, at least 5 minutes after every hour of stereoscopic 3D
viewing.
• If you experience any of the following symptoms, do not engage in any
potentially hazardous activity (for example, driving a vehicle) until your
symptoms have subsided:
• Nausea, dizziness or queasiness
• Headache or eyestrain
• Blurry vision
Double vision that lasts longer than a few seconds
If symptoms persist, discontinue use and do not resume stereoscopic 3D viewing
without discussing your symptoms with a doctor.
