Identify a method for testing visual acuity that is relevant in the ABO NOCE.

The Snellen chart is a widely recognized and established method for testing visual acuity, making it highly relevant in the context of the ABO NOCE. This method involves the use of a chart with letters or symbols of varying sizes, which are presented at a standardized distance, typically 20 feet. By asking the patient to read the smallest line of letters they can accurately identify, this test provides a quantifiable assessment of visual acuity, commonly expressed as a fraction.

The Snellen chart is critical because visual acuity is a basic yet vital component of overall eye health and vision care, allowing practitioners to determine the sharpness of a person's vision. The results can be essential for diagnosing various eye conditions, assessing the need for corrective lenses, and monitoring changes in vision over time. Other methods of examining vision, while important, do not specifically measure visual acuity in the same straightforward manner as the Snellen chart.
