An optometrist is a healthcare professional who specializes in the examination, diagnosis, and treatment of various eye conditions and vision problems. Their primary job is to assess and manage the visual health of their patients. Optometrists perform comprehensive eye examinations to evaluate visual acuity, refractive errors, depth perception, color vision, and eye coordination. They also prescribe and fit corrective lenses, such as glasses or contact lenses, to improve their patients' vision. Additionally, optometrists diagnose and manage various eye diseases, including glaucoma, cataracts, and macular degeneration. They may also provide pre- and post-operative care for patients undergoing eye surgeries. Optometrists play a crucial role in promoting eye health and preventing vision loss by educating patients about proper eye care and recommending preventive measures.
