What is the purpose of a comprehensive eye examination?

A comprehensive eye examination is primarily designed to assess overall eye health. This evaluation involves a thorough inspection of all aspects of visual function and eye health, which may include checking visual acuity, examining the internal and external structures of the eye, and evaluating how well the eyes work together. The purpose extends beyond merely determining the presence of refractive errors or prescribing corrective lenses; it encompasses the detection of various eye conditions such as glaucoma, cataracts, diabetic retinopathy, and macular degeneration.

While prescribing corrective lenses can be a part of the examination, it is not the central purpose. Similarly, checking for color blindness might be one component of the assessment, but it is not sufficient to define the overall purpose of a comprehensive exam. Performing surgery on the eyes is not part of a routine eye examination; rather, it may follow if any serious conditions are identified and require surgical intervention. Thus, the comprehensive examination focuses on ensuring the health and functionality of the eyes rather than specific treatments or tests.
