3D is the hot new media trend as of late -- but is it safe? Not for children under 6, warns Nintendo.

In anticipation of the impending Nintendo World 2011 and the launch of its upcoming portable console, the Nintendo 3DS, the influential video game company has posted a cautionary note on its Japanese website.

“Vision of children under the age of six has been said [to be in the] developmental stage,” Nintendo warned. The company fears that 3D content “delivers 3D images with different left and right images, [which] has a potential impact on the growth of children’s eyes.”

But users of all ages can succumb to the perils of 3D experience. Since the 3DS creates the illusion of 3D without the need for glasses, it can add extra eye strain, causing users to feel sick or nauseous after extended use. In July, Sony warned of similar issues with its PlayStation 3, amending its terms of service to offer a stark warning for users.

Some people may experience discomfort (such as eye strain, eye fatigue or nausea) while watching 3D video images or playing stereoscopic 3D games on 3D televisions," read Sony Online's amended terms.

The notice went to say that Sony "recommends that all viewers take regular breaks while watching 3D video or playing stereoscopic 3D games. Nintendo will be including protective measures such as parental controls, which restrict games to their 2D presentation, and recommends that users of all ages take breaks from 3D content every 30 minutes.
