A comprehensive eye exam is a complete evaluation of vision and overall eye health. It assesses visual acuity, eye alignment, eye pressure, and the health of internal eye structures such as the retina and optic nerve. The exam typically includes a review of medical and visual history, vision testing, refraction, eye muscle evaluation, and a dilated eye examination. Additional diagnostic tests may be performed based on symptoms or risk factors. Comprehensive eye exams are essential for detecting vision problems, eye diseases such as glaucoma or macular degeneration, and systemic conditions that can affect the eyes, including diabetes and hypertension. Regular eye exams support early diagnosis, accurate treatment planning, and long-term eye health at every stage of life.
