Ophthalmologists, Optometrists, Opticians

Each of these titles represent persons trained in eye care.


Ophthalmologists are MD’s or DO’s. After medical school degrees were attained they took advanced training so that they are able to offer the highest level of eye care. Ophthalmologists are highly educated to examine, diagnose and offer advanced eye care. They diagnose and prescribe medicine to treat eye diseases such as glaucoma. In addition, ophthalmologists perform eye surgery to correct problems such as macular degeneration or cataracts or for vision improvement procedures such as Lasik vision correction.


Optometrists, Doctors of Optometry (OD), are licensed to examine eyes for vision and eye health. Where surgery is required an optometrist will refer to an ophthalmologist. Optometrists can prescribe medications for eye conditions- infections, dry eye and other health problems. They prescribe eyeglasses and contact lenses. Some practices provide low vision care and vision therapy.



Opticians, licensed in most states by certified training facilities, work with Ophthalmologists and Optometrists to fit and sell eyeglasses, contacts and other optical wear.

Seneca Eye Care with offices in Warren and Jamestown serve Warren General Hospital for these three services.  To reach Seneca Eye for an Optician, Optometrist or for Ophthalmologist.
