Ophthalmologist, Optometrist, and Orthoptist: what’s the difference?

According to David Robinson Ophthalmologist, an optometrist is a doctor of optometry with a bachelor's degree in the field. Visually impaired persons can prescribe and sell glasses, contact lenses, and other visual aids. They can also check for glaucoma, cataracts, and macular degeneration, which are all serious eye problems.
