Abstract

A new vision test, incorporating textual and non-textual elements in an image, is configured to demonstrate the effects of low cylinder astigmatism and other sources of blur on visual quality. The elements are designed to be noticeable, relevant, important and engaging. The new vision test may be utilized to supplement conventional vision testing.

Claims

1. A method for demonstrating the benefits of correcting blurred vision of a patent having low levels of astigmatism comprising:

providing a set of composite images, the set including the following;

a composite image including a scene composed of textual and non-textual elements, a composite image for facial recognition and facial expression recognition having low frequency details for one face and one expression and high frequency details for a second face and a second expression, an image having high frequency details, an image having gratings and text, an image having rotating gratings, an image having an array of gratings, an image having only line drawings, an image having text in motion, an image having text in perspective, an image having text with distraction, an image having high contrast patterns, presenting at least one of the images of the set to the patient, having the patient view the at least one image through a device having adaptive lenses to correct the low levels of astigmatism, and determining the effect of the vision correction on the patient having low levels of astigmatism.
