Howling:The retinal scanner for the Eye of Harmony in the TV Movie

Can anyone think of a good explanation as to why the Eye of Harmony inside the Doctor's TARDIS in the TV Movie had a retinal scanner keyed to only respond to a human eye pattern? Actually, why was there a scanner designed to open the Eye at all, if Time Lords aren't supposed to do that? 82.2.136.93talk to me 15:12, May 21, 2012 (UTC)


 * In The Apocalypse Element all Gallifreyan technology is operated by eye-scan. When the Daleks invade the Doctor reprogrames the Gallifreyan systems to use a human's iris to prevent the Daleks from gaining access.
 * There is also the fan theory that the Eye inside the Doctor's TARDIS is just a representation of the Eye, rather than the actual Eye. So the Doctor may have programmed the representation to only respond to humans. --Tangerineduel / talk 16:10, May 21, 2012 (UTC)
