Since the Wall Street Journal article released in December, we've gotten quite a few inquiries about why there is and what the implications are about the following warning:
"Watching 3-D images for an extended time could result in adverse effect on eyesight development in the case of children 6 years old and under, therefore we highly recommend a switch to 2-D display."
As with many warning labels, we're sure Nintendo is being overly cautious to warn against the unknown. While there are no studies available on the adverse effects of 3D media on vision development, there are studies that have shown that adult-level stereoscopic development occurs by age 6. Hence, the Nintendo warning cautions use by those under 6 years old who are still developing their visual systems. Since we are unsure about how stereoscopic development may be affected by 3D media, it is prudent to limit exposure to such devices. But more importantly, it is best to limit usage of any handheld device. Dr. Mary McMains of the Vision Learning Center of Champions recommends that "a good rule of thumb is for every 15 minutes of using digital media, you should spend 30 minutes doing some sort of gross movement activity, preferably outdoors."
