Since that time, the profession has changed dramatically with an expanded scope of practice far beyond the simple prescribing of glasses. The treatment may consist of glasses, contact lenses, vision therapy exercises, or, in all 50 states and the District of Columbia, the administration of prescription drugs as regulated by state law. Also, optometrists can use diagnostic pharmaceuticals to aid in the diagnosis of systemic diseases such as diabetes and high blood pressure. Because of this, optometrists are important primary health care providers, as well as, the only eye care providers thoroughly trained in all aspects of optics and vision science. While all optometrists provide general eye and vision care, some optometrists specialize in specific areas of optometry.
Optometrists can practice in many different settings.
Some have private practices, either as a solo practice or with a partner or group. Others collaborate with other health care professionals, such as ophthalmologists, in a multi-disciplinary practice. Many optometrists practice in large corporate settings, such as Lens Crafters or Pearle Vision, while still others are engaged by the military, public health service, hospitals, teaching institutions, or the ophthalmic industry. Regardless of the type of practice, optometry is counted as one of the top ten income-earning professions in the country. In addition to the monetary rewards, optometry is a very satisfying profession since, by treating a patient's vision problems, one can improve the quality of the patient's life.
