Optometry is already a very specialised field of work and there are not a lot of further specialisations available. However, many optometrists move into full-time sales positions while others move into management roles or become owners of their own practices.
Sales
Because optometrists often work in retail settings, over time many decide they prefer the sales aspect of the business. Sales specialists have expertise in different brands and styles of glasses and optical aids and advise their clients on the best solutions to their needs.
Private practice
In addition to the day-to-day tasks of an optometrist, managers and owners of private practices are responsible for managing staff and budgets, administrative tasks and training and development.
