Colenbrander Reading Card
Colenbrander Reading Card
Near Vision, Standard Contrast (9" x 7") Designed as a simple 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.
