I had a customer come in with a contact Lens Rx from an opthamology office yesterday to order his contacts. When I reviewed the Rx everything looked fine except it was signed by the optician instead of the doc. Is that legal to fill? The optician had stamped his own name and signed where the MD usually signs, then put "for" and the docs initials underneath. I've never seen this before and was just wondering about validity of rx without the doctors signature.
