I wont go into the condescending tone of the response but the whole 'irrational' fear part like some of those you mention isnt irrational as much as a flu is irrational... or cancer. Its brain chemistry and psychology and psychiatry exist because of it.
That said, I actually do have advanced keratoconus in the right eye and 'mid' level on my left so there is that too.
You're equating fear of putting a contact lens in your eye with... the flu or cancer?
You can't possibly be serious.
As far as Kconus goes, contact lenses often provide better vision than eyeglasses because they create a new refractive surface for the eye which compensates for the irregular cornea, especially in the early stages.
