'The Nintendo 3DS, which is due to be released next year, will give users the option of playing in 3D as opposed to the conventional 2D picture, without the need for 3D glasses. But in a statement on its Japanese website, the company cautioned that children under the age of six who use the new 3D functionality could suffer from stunted eye development as a result.

Designers have even equipped the handset with a parental lock that deactivates the 3D aspect and prevents children from being able to switch it back on. The company also advises all users take breaks from playing 3D games as frequently as every 30 minutes to give their eyes a chance to rest.

The advice to consumers follows warnings from television manufacturers that children, pregnant women and drunk people could experience symptoms from nausea to seizures from watching in 3D.'
