An eye examination is a comprehensive ophthalmic assessment designed to evaluate the health and function of the visual system. During this process, instruments are used to measure visual acuity, determine refractive errors such as myopia or hyperopia, and assess the overall structural integrity of ocular components including the cornea, lens, and retina. Examination procedures often involve objective testing of visual fields and detailed inspection of the interior structures, while clinical assessments help identify potential conditions ranging from glaucoma and cataracts to retinal detachments. The goal is to detect early signs of pathology and guide appropriate management strategies to preserve sight and optimize visual function.
