A comprehensive eye examination is a thorough evaluation of the overall health of the eyes and vision. It involves a series of tests conducted by an Optometrist or Ophthalmologist to assess visual acuity, eye alignment, and the ability to focus. The exam typically begins with a review of the patient’s medical history, followed by tests such as the Snellen chart to measure visual sharpness, a refraction test to determine prescription needs for glasses or contact lenses, and an assessment of eye movement and coordination. The exam also includes an examination of the eye’s internal structures, including the retina and optic nerve, through techniques like Ophthalmoscopy or slit-lamp examination. Intraocular pressure may be measured to screen for glaucoma. Comprehensive eye exams are important not only for identifying refractive errors but also for detecting early signs of eye diseases and systemic conditions like diabetes or hypertension. Regular exams are crucial for maintaining eye health and preventing vision loss.
