Contrast Sensitivity, Near Vision Charts, Ophthalmic Clinical Research, Other chartsRabin Super Vision Test
This Super Vision test includes visual acuity and letter contrast sensitivity (CS) on a single chart. The top portion of the chart tests for acuity vision while the bottom half includes highly calibrated levels of contrast. Chart includes eight separate contrast levels for the most precise contrast sensitivity test. This eye chart also includes a separate optotype sequence for each eye to reduce memorization possibilities. This test is designed for use with the Small 914 Illuminator Cabinet.

Contrast Sensitivity, CSV2000
CSV 2000
With the CSV-2000, you have the power to test for more than just acuity and contrast sensitivity
AcQviz measures the monitor light level and adjusts the level to 85 cd/m2.
The CSV-2000 is the only clinical digital vision testing device that automatically calibrates the monitor lighting so that all testing is conducted at the same light level. This standardization ensures consistent vision test results from room-to-room and from practice-to-practice. Auto-calibration is accomplished through patented technology from Guardion Health Sciences (Parent Company of VectorVision), called AcQviz.
