Good-Lite LEA Symbols Translucent Low Contrast Chart for Illuminated Cabinet
The purpose of a low contrast test is to measure visual acuity, determining how well eyes function in low light situations and/or being able to distinguish objects from similarly colored or shaded backgrounds. The testing process is identical to the measurement of visual acuity at high contrast level. The 2.5% test is the most practical test in clinical use.
- This chart is to be used in an ESV1200 or Model A+ illuminated cabinet.
