What does the measurement 20/15 mean in ophthalmology?

The measurement of 20/15 in ophthalmology indicates that a person can see at 20 feet what a person with normal vision can see at 15 feet. This means the individual has superior vision, as they can see finer details at a greater distance than the average person. Normal vision is typically classified as 20/20, so achieving a measurement of 20/15 highlights the ability to perceive smaller letters or objects more clearly at a distance, demonstrating enhanced visual acuity. This distinction is crucial in assessing vision quality and determining whether an individual may have exceptional eyesight.
