MNRead Chart 1 In English Black Background
Contrast Sensitivity, Near Vision Chart, Near Vision Charts, Ophthalmic Clinical ResearchMNRead Chart 1 In English Black Background
The MNREAD Acuity Charts are continuous text reading acuity charts for normal and low vision.
Often times traditional vision charts only measure general parts of normal vision, such as acuity and contrast. However, many times everyday life scenarios place these two aspects in unique situations. For example, acuity is very important in vision. Testing acuity normally involves a standard eye test. However, when reading the newspaper, the eyes are challenged by small print, continuous text, and several close contact lines. This basic living situation may cause problems for patients with scotomata and may not be detected on conventional acuity charts. Continuous text charts give one more possibility during vision testing.
