The person in Specsavers who examines your eyes is an optometrist. Optometrists will be trained in a subject such as Vision Science and are concerned with the optical properties of the eye. Their training will include being able to identify pathologies that can not be corrected by optical means and they will refer such conditions to ophthalmologists.
An ophthalmologist is a doctor who specialises in diseases of the visual system and will typically work in a hospital.
The reviled President Assad of Syria was, I believe, an ophthalmology registrar in a London hospital. If he is deposed, I don't think that he will get his old job back.
