A method of vision testing includes providing a display, presenting a first chart of optotypes wherein each line progressively decreases in size or in contrast of the optotype relative to a background. The method includes having a patient identify and read the optotypes, noting which line of optotypes at which the patient can correctly identify all of the optotypes in the first chart, confirming that the patient has correctly identified all of the optotypes in the line of the first chart, and then presenting a second chart of optotypes wherein each line of the second chart progressively decreases in one of size or in contrast of the optotype relative to a background. The size or contrast of the noted line of optotypes from the first chart that the patient correctly identified is presented as either a first line of optotypes or a second line of optotypes on the second chart.
