Nintendo 3DS Causing Headaches?

Recently, Nintendo issued a warning against children under the age of seven using its Nintendo 3DS. Apparently, the handheld's 3-D feature can potentially impair their still-developing eyesight.

To combat this issue, the publisher displays a prominent warning on every game box. Of course, that didn't stop us from wincing as we read the user complaints rack up on Twitter about headaches and dizzy spells caused by the 3D-capable screen.

There's a larger list of complaints compiled by the good folks at MaxConsole, and famed comic Penny Arcade takes a jab at the problem in their latest strip. Our own advice? Use the slider on the right of every 3DS to turn down or off the 3-D effects. It's OK to rely on that "boring" 2-D mode.
