An optometrist is a medical professional who provides vision and eye care. An optometrist assistant, also called an “optometric assistant,” works with the optometrist to ensure the office runs smoothly. As an optometrist assistant, your job duties include scheduling appointments, filing paperwork, handling other bookkeeping tasks, and answering the phone. You may also have some clinical responsibilities, such as performing pretests for vision exams, prepping exam rooms, cleaning and setting up equipment, and showing patients how to care for contact lenses.
