four (4) or more years of medical school
one (1) year minimum of internship
three (3) or more years of specialized medical, surgical, and refractive training and experience in eye care.
An ophthalmologist is licensed by a state regulatory board to practice medicine and surgery.

An optometrist is a health service provider who is primarily involved with vision problems. Optometrists are specifically educated and trained by an accredited optometry college in a four-year course. Optometrists do not attend Medical School. They are state licensed to examine, diagnose, and treat vision problems, including determining visual acuity and prescribing eyeglasses and contact lenses. They can administer and prescribe some drugs, as approved by the Secretary of Health. Optometrists in Pennsylvania may use topical pharmaceutical agents in the treatment of some forms of glaucoma. They may not treat systematic diseases. They may not perform surgery, including the use of lasers and injections.
An optician is a professional technician who makes, verifies, delivers and fits lenses, frames, and specially fabricated optical devices and/or contact lenses under prescription.
The optician's functions include:
prescription analysis and interpretation
determination of the lens forms best suited to the wearer's needs
the preparation and delivery of work orders for the grinding of lenses and the fabrication of eyewear
the verification of the finished ophthalmic products
the adjustment, replacement, repair, and reproduction of previously prepared ophthalmic lenses, frames and other specially fabricated ophthalmic devices
