Optometry is a healthcare profession concerned with the eyes and related structures, as well as vision, visual systems, and vision information processing in humans. Optometrists are trained to prescribe and fit lenses to improve vision, and in some countries are trained to diagnose and treat various eye diseases.
The optometry profession is defined by the World Council of Optometry (WCO) as follows:
“Optometry is a healthcare profession that is autonomous, educated, and regulated (licensed/registered), and optometrists are the primary healthcare practitioners of the eye and visual system who provide comprehensive eye and vision care, which includes refraction and dispensing, detection/diagnosis and management of disease in the eye, and the rehabilitation of conditions of the visual system.”
Optometrists can diagnose, restore or correct the dysfunctions of vision with glasses, lenses, filters, visual aids or programs of visual training / vision therapy.
