Near Vision Unit NV-100
Near Vision Unit 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
