optometry
This term refers specifically to the clinical and primary healthcare side of vision care, focusing on the measurement of visual acuity and the fitting of corrective lenses. It is distinct from ophthalmology, which involves medical and surgical treatment of the eye. While an optometrist provides the initial diagnosis and prescription, an ophthalmologist is a medical doctor who can perform surgery.
As a field of study or a professional practice, the word functions as an uncountable noun. It describes a collective body of knowledge and a professional discipline rather than a discrete object that can be counted.
Meanings
The professional practice of examining the eyes for vision defects and prescribing corrective lenses or treatments.
