System and method for relieving eye strain
First Claim
1. A method for relieving eye strain, eliminating eye accommodative disorders, and exercising the ciliary muscles of the eyes, comprising:
- (a) activating a laser display which displays a laser interference pattern in the form of a random speckle pattern;
(b) receiving an input from a viewer indicating that said viewer perceives said laser interference pattern; and
(c) producing a dynamic alteration of said laser interference pattern;
wherein said dynamic alteration of said laser interference pattern is operative, by means of producing visual stimuli, to stimulate changing of eye accommodation of said viewer.

Abstract
The invention provides methods and apparatuses for vision therapy procedures using laser interference patterns for relieving eye strain. One of the methods provided controls a speckle pattern in such a manner that an interesting visual stimulus is created which attracts and retains a viewer'"'"'s attention and forces the eye to adjust to distance vision. This stimulates relaxation of the ciliary muscles of the viewer'"'"'s eyes and contributes to the relief of eye strain. Another method provides electronically generated holograms for exercising eye muscles in order to relieve eye strain. The present invention provides further methods and apparatuses which may be used in a computer user'"'"'s workplace.

15. An apparatus for relieving eye strain and for exercising eye muscles, comprising:
-
(a) a computer;
(b) a laser interference pattern display unit coupled to said computer, comprising one or more spatial light modulators, and one or more diffuse light scatterers, and (c) a computer software program implemented on said computer operative to control said laser interference pattern display unit;
wherein said laser interference pattern display unit produces a laser interference pattern which is dynamically varied so as to require a viewer'"'"'s eye to adjust between distant and near vision in accordance with instructions of said computer software program and in order to relax or, alternatively, relax and contract ciliary muscles of said viewer'"'"'s eye. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A computer-readable medium containing a computer program for relieving eye strain, comprising:
-
(a) computer executable instructions for controlling an eye strain relief device, comprising;
(i) a first instruction for activating and deactivating a laser display operative to display a laser interference pattern;
(ii) a second instruction for processing an input from a viewer indicating that said viewer perceives said laser interference pattern; and
(iii) a third instruction for producing a dynamic alteration of said laser interference pattern to stimulate relaxation of ciliary muscles of said viewer;
(b) a set of digital data for generating a plurality of laser interference patterns; and
(c) a set of digital data for dynamic control of said laser interference patterns. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)

32. An image display unit capable of providing eye strain relief and eye exercise in addition to displaying conventional alphanumeric, graphic, and other types of images, comprising:
-
(a) a visual display unit for displaying alphanumeric, graphic, and other visual information, said visual display unit using a display means selected from the group consisting of;
an electron-beam tube, a liquid crystal display, and other non-laser display means; and
(b) a laser display unit comprising one or more spatial light modulators, said laser display unit operative to display laser interference patterns, said laser interference patterns selected from the group consisting of;
random speckle patterns, regular interference patterns, and three-dimensional images;
wherein said laser interference patterns contribute to the relief of eye strain and exercising of eyes when a viewer looks at said laser display unit. - View Dependent Claims (33, 34, 35, 36, 37, 38)
