Abstract:

In everyday life, perhaps the most important aspect of vision is the ability to see and recognize objects. This ability is commonly assessed by procedures such as the Snellen test in which the patient reads smaller and smaller letters. The smaller the letters that can be accurately recognized, the better the patients spatial vision is conventionally assumed to be. This assumption seems to be intuitively obvious, so that a 2020 Snellen score has become a household word for clear and acute vision. Recently, however, it has grown clear that some patients retain a normal ability to see small objects while their ability to see larger objects is degraded. The claims of such a patient that his vision was weak or washed out in an eye with 2020 acuity might once have been difficult to attribute to organic pathology since the symptoms are quite different from those associated with refractive disorders of vision. js
