What are the differences between ophthalmologists and optometrists?

Ophthalmologists are medical doctors who have completed four years of medical school, a one-year internship in general medicine, and three years of residency in ophthalmology. They are licensed to practice medicine and surgery and can prescribe medications.

Optometrists are Doctors of Optometry (ODs). They complete four years of college education in optometry and receive a Doctor of Optometry degree. They are licensed to diagnose and treat many eye diseases and conditions but cannot prescribe medications.
