In the United States, opticians are not doctors, but in some states they must complete training and be licensed. And in some states they can, after special training, become certified to fit contact lenses. (Please visit the Opticians Association of America website for licensing requirements for various states.) Most opticians sell and fit eyeglasses, sunglasses, and specialty eyewear that are made to an optometrist's or ophthalmologist's prescription. Many also have equipment on the premises so they can grind lenses and put them in frames without ordering from a lab.
