Patent number: 8152301Abstract: A method for testing a person's vision is disclosed. The method includes providing, for display to the person, one or more sequences of test images, each test image including one or more test symbols. For each test image, a target symbol is identified to the person. The person then views each test image in the sequence and activates a control in response to recognizing a test symbol that replicates the shape of the target symbol. At the completion of the sequence, a parameter value associated with the activations is processed and correlated with a vision metric. A system for testing a person's vision is also disclosed.Type: GrantFiled: November 15, 2006Date of Patent: April 10, 2012Assignee: Carl Zeiss Vision Australia Holdings LimitedInventors: Scott Warren Fisher, Warwick Freeland
