Visual orthotic device technicians, more commonly referred to as dispensing opticians, offer advice to clients when choosing frames, lenses and contact lenses. They determine specifications for glasses and contact lenses based on prescriptions and take measurements and adjust glasses with the help of optical instruments. In optical centres, they provide patients with information on the use and maintenance of visual orthotics. A job as a visual orthotic device technician requires attention to detail, politeness and interpersonal skills. It is a job that requires sales and customer service skills, fine dexterity and a good sense of aesthetics.
