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.

First claim

What is claimed is:

1 . A reproducible image for demonstrating the benefits of correcting blurred vision
comprising a scene composed of one or more of textual and non-textual elements having one or more of the following properties, including facial recognition and expressions, high frequency details, gratings and text, rotating gratings, array of gratings, line drawings, text in motion, text in perspective, text with distraction and high contrast patterns, wherein the scene is noticeable, important and engaging.

2 . A system for demonstrating the benefits of correcting blurred vision comprising:
a scene composed of one or more of textual and non-textual elements having one or more of the following properties, including facial recognition and expressions, high frequency details, gratings and text, rotating gratings, array of gratings, line drawings, text in motion, text in perspective, text with distraction and high contrast patterns, wherein the scene is noticeable, important and engaging; and a device for providing incremental cylinder correction.

3 . A system for demonstrating the benefits of correcting blurred vision comprising:
a scene composed of one or more of textual and non-textual elements having one or more of the following properties, including facial recognition and expressions, high frequency details, gratings and text, rotating gratings, array of gratings, line drawings, text in motion, text in perspective, text with distraction and high contrast patterns, wherein the scene is noticeable, important and engaging; and a device for demonstrating presbyopic vision correction.

4 . The system for demonstrating the benefits of correcting blurred vision according to claim 4 , wherein the device for providing incremental cylinder correction is a flipper tool.
