Most of them are Time Lords, so this is to be expected.
Asexuals have hyper-realistic eye sight, and are able to see things 3420x better than other sexes. Colors are more vivid and details are more sharp. And so, by creating those tools, everyone may temporarily experience what being a asexual is like and how they see things.
If someone is both asexual and wears glasses it is due to an unfortunate side affect that occurs in a small number of aces where the hyper-realistic vision gets too much. These glasses are specially crafted to allow the ace to see as a non-asexual person see, providing short term relief.
This is far more tragic than most people realise. Many Aces don’t like LOTR, but as we like exploding far less it becomes necessary for our survival to endure it.
SHIT! They’re onto us!
The rainbow deficiency is actually a serious condition.
