Wearing a Single Contact Lens

I have the same contact prescription in both eyes. When I put one of
my contacts in the eye gets red and becomes painful. I'm am making an
appointment with opthamologist.

Today, I'm only wearing one contact lens because I don't have a set of
glasses with me (left them out of town and won't get them back for a
week). Does it damage my eyes to wear only one of my presciption
contacts? At least this way I can drive... sort of... for short
distances

Thanks.
