Ophthalmology is a medical specialty that deals with eye or ocular anatomy, physiology, functions, pathology, conditions, and treatment. Medical practitioners who specialize in this field are called ophthalmologist, who may be also surgical or medical specialists since they also perform operations on the eyes. The term ophthalmology literally means "the science of eyes" given the Greek root words "ophthalmos" (which means "eye") and "logos" (that translates to "thought" or "discourse" in English).
Aside from medical and surgical treatment, the practice of ophthalmology also includes vision measurements for the selection of appropriate glasses, eye muscle exercises, the prevention of blindness, and care for the blind or visually impaired.
