Ophthalmologists, optometrists, opticians and ocularists all provide crucial eye care services. It is important to understand what each of the "Os” is qualified to do. A National Consumers' League (NCL) survey found that many consumers are confused about the differences among various eye care providers, the services they perform, and the training and education they must complete (https://nclnet.org/who_does_what_consumers_confused_about_eye_care_providers_training_m_d_status/)
Ophthalmologist
An ophthalmologist, or Eye MD, is a physician, either a Doctor of Medicine, MD, or Doctor of Osteopathy, DO. An ophthalmoloigst is a medical doctor who graduates from medical school, specializes in all aspects of eye care including

Treat ocular manifestations of systemic diseases
Prevention of eye disease and surgery
Scientific research into causes, cures for eye diseases, vision problems
Licensed by state regulatory board
Ophthalmologists routinely conduct many of the same tasks as optometrists. There are twice as many practicing optometrists as ophthalmologists, but ophthalmologists perform about one-fourth of the nation's refractions and eye examinations (“The Eye Care Team - American Academy of Ophthalmology”)
Ophthalmology education and training is a minimum of twelve years of training which includes
Four or more years of college premedical education
Four or more years of medical school
Extensive clinical and surgical training, thousands of hours in care and treatment of sick patients
One year of internship

TPA certified optometrist may treat certain diseases, abnormal conditions of human eye and adnexa with therapeutic pharmaceutical agents (TPA) as specified by law (Source: Virginia Code, 54.1-3220).
