Optical vision tester NV-100 Near vision tester

 

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
