How long does it take to correct astigmatism?

Question

I'm using contact lenses that correct astigmatism. How long will it take?

Answer 1

Unless these are of the Ortho-K type that you sleep overnight in, with the aim of not using them during the day (and I've not heard of them being used where the principal problem is astigmatism), they don't correct the eyes in the sense you imply.

Contact lenses correct astigmatism the same way that ordinary contacts or glasses correct short-sight: while they are being worn and only while they are being worn.  Not with the intent of making the eye better in the long term.

They don't "straighten the eye out" the way braces on the teeth do in orthodontistry.
