Nintendo has issued a statement in response to user complaints of headaches or eyestrain after use of the 3DS.
"We have shown Nintendo 3DS at multiple events around the world to literally hundreds of thousands of people and have received very few negative comments," Nintendo UK's PR big man, Rob Saunders, told Maxconsole.
"As with anything that requires focus, from reading to staring at a computer screen, taking breaks frequent breaks is always recommended. When viewing any kind of 3D images (TV, movies etc.), some people might experience minor discomfort. The effects are short term and have no lasting effect, in fact most players can continue after taking a short break," he added.
"The Nintendo 3D was designed with a 3D depth slider that lets users adjust the 3D effect to a level that suits them for optimum enjoyment."
This editor has played 3DS for extended periods of time without issue.
Nintendo earlier today also issued a response regarding the now dubbed 'black screen of death' that has been seemingly rendering 3DS units unusable.
