We had carried a report on the health risks involved with Nintendo 3DS' autostereoscopic (glassless 3D) display, and reports from the recently concluded Nintendo World event seem to confirm the same. A Japanese magazine called Friday claims that a "majority" of visitors who tried out 3DS at the event experienced 3D induced side effects like eye-fatigue and dizziness, when they used the 3D functionality of the portable.
Friday spoke to visitors, who sampled the 3DS, and found that many of them switched from 3D to the 2D mode within a few minutes citing minor dizziness. A word of caution, as Friday is known for its tabloidesque reportage, let's not jump to any hasty conclusions. However, this does carry some credence as all 3D displays that we have tried tend to cause fatigue within a few minutes of usage.

We all knew 3DS can cause this, but come on many people switching from 3D to 2D mode in a matter of minutes. Is it really critically affecting a lot of people? It’s just so damn quick and seems like quite a few people won’t be enjoying 3D. I just hope I don’t fall into that because I’m energized to play hours in 3D mode =D
EDIT: Another source reporting
QUOTEWeekly tabloid Friday claims that a majority of users reported signs of dizziness and/or eye fatigue and people were quick to turn off the 3D features.
Even the writer of the story claimed to have experienced symptoms after a bash on the 3DS. "After playing for 10 minutes, I started feeling a little dizzy", he said. "It was like being seasick".
Another user said after a minute's play: "I can't bear it" and stated that his eyes felt "tired".
We're not pouring scorn on the Friday story, but we haven't heard many other reports of the 3DS causing sickness or dizziness, so we'll reserve judgement for now.
