Should I throw a contact lense away if I stepped on it? (READ INFO)?!

A couple minutes ago I was reading a article on NYT and my right eye started watering after I blinked so naturally I rubbed my eyes, however I noticed a decrease in vision for my right eye and went to the bathroom and tried to remove the contact lense in my right eye. However, after a good 10 minutes, I couldn't do it so I decided to take off the contact lense in my left eye. I then put on my trusty backup pair of glasses. When I went into the bathroom to turn off the lights, I saw, what looked like, a piece of plastic on the floor. Naturally I picked it up and figured out it was my contacts. So I appliied the cleaner solution and saw that the lense sorta had a crease in it. I decided to put it on my index finger to see if it would fix itself. After a minute I saw that the lense had straightened out. So, my fellow Yahooers, should I keep the lense, or throw it away? I'm kinda new at contacts because I got them on 12/11/2010
