What distinguishes vision screening from a comprehensive eye examination?

The distinction between vision screening and a comprehensive eye examination is fundamental in understanding how eye health is assessed. Screening is designed to identify individuals who may be at risk for vision problems or who may need further evaluation. It typically involves quick tests that can indicate potential visual impairments without providing a detailed diagnosis.

In contrast, a comprehensive eye examination is a thorough assessment conducted by an eye care professional, which involves a detailed evaluation of various aspects of eye health. This examination can lead to a definitive diagnosis of eye conditions, as it includes tests that assess visual acuity, the health of the ocular structures, and even the overall health of the patient.

Thus, the correct answer highlights that screenings identify potential issues that need further investigation, whereas comprehensive examinations are instrumental in providing an accurate diagnosis and guiding subsequent treatment. The clarity of this distinction ensures proper referrals and management of eye health concerns.
