Optometry
Optometry is a specialized health care profession that involves examining the eyes and related structures for defects or abnormalities. Optometrists are health care professionals who typically provide comprehensive eye care.

In the United States and Canada, optometrists are those that hold a Doctor of Optometry degree. They are trained and licensed to practice medicine for eye related conditions, in addition to providing refractive (optical) eye care. Within their scope of practice, optometrists are considered physicians and bill medical insurance(s) (example: Medicare) accordingly. In the United Kingdom, optometrists may also provide some medical care (e.g. prescribe some medications) for eye related conditions in addition to providing refractive care. The Doctor of Optometry title can also be used in the UK for those that hold the postgraduate O.D. degree.

Many optometrists participate in academic research for eye-related conditions and diseases. Optometrists receive training in refraction and monitoring of common uncomplicated eye conditions. They are not trained in any forms of surgery or laser procedures. Ophthalmologists are medical doctors and surgeons who typically hold a four-year college degree, a four-year medical degree, and at least four years of residency training after medical school.
