Projection field of vision analyzer APPZ-01. A modification of the well-known perimeter PRP-60, the visual field analyzer is designed to determine the light and color sensitivity of the retina under conditions of light and color adaptation for day, twilight and night vision. The analyzer provides determination of the peripheral boundaries of the field of view, detection of its central defects. The new modification is distinguished by stable photometric characteristics, well-thought-out ergonomics, and high performance.
