and eyes in their normal posture at any working distance.

• The refractive tests include:

• Measurement of visual acuity using Snellen letter and illiterate E-chart, and Times Roman reading types.

• Accurate determination of presbyopic additions and other near corrections.

• Near vision astigmatism tests.

• Amplitude of accommodation including monocular measurements under binocular conditions.

• The Binocular balance tests include:

• Fixation disparity test for uncompensated heterophoria motor eye dominance.

• Accommodation-convergence relationship.

• Quantitative evaluation of foveal suppression in heterophoria patients.

• Near point of convergence.

• Targets for subjective cover tests for heterophoria and harmonious ARC.
