Most of the feedback we received from our readers regarding the Sun's report of 3DS sickness tend to support the Japanese console manufacturer rather than the UK tabloid publication.
Many point to the fact that playing any form of video games can cause problems, just like flashing images during the news can cause epilepsy. In which case, it is recommended to follow the advices on the box and adjust the 3D depth slider, take regular breaks (every 30 minutes) and play in well lit conditions.
This mechanism allows users to control the amount of 3D effect they want to see on street. Nintendo has even added PIN control which prevents kids from changing the 3D depth slider (or enable autostereoscopic effects) and run any potential risks.
Others underlined the fact that the 3D mode in the 3DS shouldn't be used by children aged six or below; Nintendo published guidelines last year supporting this move citing possible harm to their still developing vision.
One of our readers told us how he played for he played for about eight hours on one day with the 3D slider set to around half without encountering any adverse effect. He did say however that he found himself trying to focus through web pages afterwards as his eyes tried to adjust.
