Optometry

Optometry (from Ancient Greek ὄψις (ópsis), meaning "eye", and μέτρον (métron), meaning "measure") is the healthcare practice concerned with examining the eyes for visual defects, prescribing corrective lenses, and detecting eye abnormalities. In the United States and Canada, optometrists hold a post-baccalaureate four-year Doctor of Optometry degree. They are trained and licensed to treat some eye-related conditions, in addition to providing refractive (optical) eye care. In the United Kingdom, optometrists may also provide medical care (e.g., prescribe medications and perform various surgeries) for eye-related conditions in addition to providing refractive care. The Doctor of Optometry degree is rarer in the UK. Some optometrists participate in academic research for eye-related conditions and diseases. In addition to prescribing glasses and contact lenses for vision-related deficiencies, optometrists are trained in monitoring and treating ocular diseases. Training for optometrists varies greatly between countries. Some countries only require certificate training while others require a doctoral degree.
