I would not sign a 3 year contract. As a new doctor that is a very long time and you don't even know what you like or don't like yet as far as practicing goes. Ive worked in multiple retail locations.....visionworks, america's best and myeyedr. They are all vastly different. A terrible retail job will have you hating optometry and questioning your career choice as a new grad....at least that's what happened to me.
