Sharp PG-LX3500 User Manual

 

■

Under normal conditions, viewing stereoscopic 3D images is safe for any duration that you would 

normally view your screen. However, some people may experience discomfort. The following 

precautions are recommended to minimize the potential for experiencing visual problems or any 
adverse symptoms.

 

■

Take regular breaks, at least 5 to 15 minutes after every 30 to 60 minutes of stereoscopic 3D 

viewing.

 

* Based on the guidelines issued by the 3D Consortium revised December 10, 2008.

 

■

Maintain an appropriate distance from the screen. Viewing from too close a distance can strain 

your eyes. If you experience eye strain, immediately discontinue viewing.

If you experience any of the following symptoms during viewing:

•  nausea, queasiness/dizziness, headache, blurry vision or double vision that lasts longer than few 

seconds

Do not engage in any potentially hazardous activity (for example, driving a vehicle) until your 

symptoms have completely gone away. If symptoms persist, discontinue use and do not resume 
stereoscopic 3D viewing without discussing your symptoms with a physician.

• As you get more comfortable viewing stereoscopic 3D:

•  Adjust the parallax on the 3D-video playback equipment. (You may not be able to adjust the 

parallax on some models of equipment.)

•  Adjust the projected image to the most comfortable viewing size by zooming. 

  (Projecting images on the smallest or largest screen size possible may eliminate the stereoscopic 

effect and strain your eyes.)

•  Use the DLP

®

 Link™ Invert function to properly set the video for your left and right eyes. (For 

details on using “DLP

®

 Link™ Invert”, see the section on its operation in this operation manual.)
