It sounds like a classic urban myth,
the sort of thing that would be shared wildly until counteracted by Snopes.
However, Taiwanese undergraduate Lian Kao really has been blinded as a result of not changing her
contact lenses.
The space between contact lenses and
the eye is well suited to allowing microorganisms that don't like oxygen to
breed, and worse still, feed on the cornea. Acanthamoeba represents the
main threat, and in Kao's case six months of not removing her lenses gave it
ample time to become established.
