title: Expanding the limits of the Teller Visual Acuity Cards.
abstract: A nomogram is presented that permits quick determination of Snellen visual acuity values for the Teller Visual Acuity Cards at distances up to 10 feet. With this nomogram, it is now possible to determine visual acuity in nonverbal populations, other than infants, while taking into account the effect of refractive error, especially myopia. The formula for constructing the nomogram is also included as generated by the Lotus 1-2-3 spreadsheet.
