Summary of tests:
The NV-100 near vision tester enable a complete refractive and binocular vision investigation to be carried out with the head and eyes in their normal posture at any working distance.
The refractive tests include:
■ Measurement of visual acuity using Snallen 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.
■ A centimeter ruler for measuring working and testing distance is included.
■ The chart can be illuminated individually by means of an infra red remote controller
