Can you really pull out pupil or cornea with your contact?

I have daily contacts and I have an appointment tomorrow. I am saving my last pair for then, and because of my prescription ran out I have a little less to make it. I am wearing my daily contacts for two days in a row. I heard a myth that if you do this, you can pull out your pupil or cornea with your contact. Is this true or a myth?

You cannot pull out your pupil-the pupil is simply a hole in the Iris which allows light to pass through. And no, you would not be able to pull out your iris.

There is a risk of damage to your cornea depending on what type of contact lenses you have and the enviroment you are in-if its dry enough and your eyes dry out then the contact lenses can "stick" to the cornea which is pretty delicate and sensitive to tearing. On the plus side in the event of damage although very painful it shouldn't make you go blind as the cornea can repair itself. 

Edited to add that chronic corneal irritation/damage will cause blindness.
