Sony recently added to it’s Terms of Service a section outlining possible risks gamers take when playing games in the third dimension. The new terms make it clear that playing 3D games for a long time can cause eye discomfort, fatigue and possibly nausea. Furthermore it mentions that it advises against children under six to play 3D games because their vision is still developing. For everyone else the terms also mention that you should take frequent breaks while enjoying the awesomeness of your 3D games.
