Salaried jobs for optometrists were primarily in offices of optometrists; offices of physicians, including ophthalmologists; and health and personal care stores, including optical goods stores. A few salaried jobs for optometrists were in hospitals, the Federal government, or outpatient care centers including health maintenance organizations. Almost one third of optometrists were self-employed and not incorporated.
