During a routine eye exam, which is typically the first procedure performed?

During a routine eye examination, visual acuity testing is usually the first procedure performed. This initial test assesses how well a person can see at various distances, which is critical for establishing a baseline for the patient's vision and determining if there is a need for corrective lenses. Visual acuity serves as a fundamental measure that helps guide the eye care professional in further evaluations and diagnostic procedures.

By starting with visual acuity testing, the examiner can quickly identify any immediate concerns related to a patient's sight, which can be further explored with additional tests as needed. This step is essential because it informs the optometrist about the effectiveness of the patient's current eyeglass prescription, if applicable, and plays a crucial role in the overall assessment of eye health and function. Therefore, the selection of visual acuity testing as the primary initial test in a routine eye exam is based on its importance in evaluating the visual capabilities of the patient.
