This is a person who fits and dispenses glasses and other corrective visual devices.  Once you have a glasses prescription (from an optometrist or ophthalmologist) this is the person who actually measures your face and fits your glasses. They measure your pupillary distance, vertex distance, and determine where your bifocal should sit. They build the glasses and make sure they work properly.

Dr. Timothy Root is a practicing ophthalmologist and cataract surgeon in Daytona Beach, Florida. His books, video lectures, and training resources can be found at:
