Will The iPod touch 5G Camera Scratch When Set On A Table ?

Since the iSight camera of the iPod touch sticks out, I was wondering if the camera lens would get scratched when set on a table since it lays on the camera instead of laying on the back of the iPod. I always use a case because of this reason, but I want to know that if I can set it on a table without it getting scratched. Thanks, in advance (;
