This configuration allows for testing vision under several different luminance levels with optional charts in high contrast, low contrast and threshold contrast and different test distances.


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.

Continuous text cards simulate everyday tasks and activities that patients may encounter, such as reading the newspaper.
Designed as a simple screen test. The usual question for a reading test is: What is the smallest (black) line you can read? On the contrast card one adds the question What is the smallest (grey) line you can read? The difference between the two measurements will be obvious and can simply be expressed in lines. Preliminary findings indicate a 2 or 3 line difference is normal.
Unrelated simple sentences at 4th grade level.
Serves as an educational tool to demonstrate the effect of contrast deficits to patients and family members.
