A new vision test chart demonstrates effective contrast sensitivity measures in a wide age range, suggesting practical applications.
A new contrast sensitivity vision chart has been tested and compared to an automated video‐based vision tester on 83 observers whose ages ranged from 9 to 75 years. Good agreement was found between the contrast sensitivity measurements obtained from the vision chart and the automated tester for similar population and age variations. These results suggest that vision test charts can be developed to provide useful contrast sensitivity psychometric functions and yet be as simple to use as present eye charts.
