Optometry is a healthcare profession focused on the examination, diagnosis, and management of vision problems and eye health. Optometrists are trained professionals who provide primary vision care, including sight testing, prescribing corrective lenses, and detecting eye abnormalities. Although they are not medical doctors, they hold a Doctor of Optometry (OD) degree and play a key role in identifying common vision issues like nearsightedness, farsightedness, and astigmatism.

Optometrists also screen for serious eye conditions such as glaucoma, cataracts, and macular degeneration, referring patients to ophthalmologists when specialized care or surgery is needed. In many regions, they are authorized to prescribe medications and offer vision therapy. Regular eye check-ups with an optometrist are essential, especially for individuals with diabetes or high blood pressure, as these conditions can impact vision. Optometry plays a crucial role in preserving eye health and preventing vision loss through early detection and management of ocular issues.
