7. Ophthalmology
Ophthalmology may seem like the business of glasses and contact lenses only but there is much more to it than just selling varied brands of glasses.
Ophthalmologist, according to the American board of Ophthalmology, are “physicians who specialize in comprehensive eye and vision care. They are the only eye care practitioners medically trained to diagnose and treat the full range of eye and visual problems.”
After medical school, you will need a good four years before being certified, including three years of residency.
