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)

But why was there a means of opening the Eye in the first place, as it's evidently such a hazardous thing to do? It doesn't make sense. 82.2.136.93talk to me 21:38, May 22, 2012 (UTC)


 * well, the eye is the power source for the TARDIS, and we don't really know how it works, so there could be any number of reasons to open the eye, under safe conditions, that are more legitimate than stealing the Doctor's regenerations.Icecreamdif talk to me 21:42, May 22, 2012 (UTC)
