Twenty-four subjects were examined by two examiners using a diamond card, a vertical/horizontal row of 20/20 letters, and a reduced Snellen Chart for nearpoint tests. The tests included the #138, modified #16A & B, modified #17 A & B, #18, #20, #20 phoria, #21, and #21 phoria from the Optometric Extension Program 21-point exam. The data was analyzed using a two- factor analysis of variance. The authors have shown that the results of nearpoint tests are dependent on the nearpoint card used.
