Category talk:Optical illusions

Untitled

Hello everybody, the correct term would be "visual illusions" instead of "optical illusions". The reason is that the optics (of the eye) are just one piece of the visual system, and they are not the place where the illusion takes place. I am not versed in the technical issues of Wikimedia, so I don't know how to correct the category name.— Preceding unsigned comment added by Strasburger (talk • contribs) 11 June 2011 (UTC)
