Near Vision Chart, Ophthalmic Clinical ResearchColenbrander Reading Card Low Vision and Mixed Contrast English
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.
