Optometry is a health care profession that involves examining the eyes and applicable visual systems for defects or abnormalities, as well as diagnosing and managing eye disease. Optometrists are healthcare professionals who provide primary eye care through comprehensive eye examinations to detect and treat various visual abnormalities and eye diseases. Being a regulated profession, an optometrist’s scope of practice may differ depending on the location. Thus, disorders or diseases detected outside the treatment scope of optometry (i.e. those requiring certain surgical interventions) are referred out to relevant medical professionals for proper care, more commonly to ophthalmologists who are physicians that specialize in the tertiary medical and surgical care of the eye. Optometrists typically work closely together with other eye care professionals, such as ophthalmologists and opticians, to deliver quality and efficient eye care to the general public.
