Abstract
Abstract Color imaging projection apparatus for projecting a pair of laterally spaced, collimated, colored light beams onto the iris portion of an individual's eyes while viewing him/herself in a two-way mirror. A housing is provided wherein is located a light source, a color wheel, a pair of laterally spaced, optical collimating rods, and a front-surfaced mirror. Light from the light source passes through a selected color filter of the color wheel, through the optical collimating rods which transmit two discreet, colored beams of light onto the front-surfaced mirror which, in turn, directs the beams of colored light through the two-way mirror to the individual located on the opposite side thereof. The individual positions him/herself with the colored light beams impinging the iris portion of their eyes as the individual views him/herself in the two-way mirror. The invention is useful in marketing colored contact lenses in that it enables an individual to visualize him/herself with different colored eyes without the need for application of trial colored lenses onto the individual's eyes.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
113 words
Apparatus for projecting colored light onto the iris portions of an individual's eyes comprising: a) a light source; b) a two-way mirror having first and second surfaces; c) at least one color filter positioned between said light source and said two-way mirror; and d) optical collimating means for collimating and directing at least one discreet light beam, as emitted by said light source and colored by said at least one color filter, through said two-way mirror from said first to said second surface thereof whereby an individual viewing him/herself in said second surface of said two-way mirror is able position him/herself with said at least one collimated, colored light beam striking their iris.
Claim 2
Dependent Claim
113 words
Apparatus for projecting colored light onto the iris portions of an individual's eyes comprising: a) a light source; b) a two-way mirror having first and second surfaces; c) at least one color filter positioned between said light source and said two-way mirror; and d) optical collimating means for collimating and directing at least one discreet light beam, as emitted by said light source and colored by said at least one color filter, through said two-way mirror from said first to said second surface thereof whereby an individual viewing him/herself in said second surface of said two-way mirror is able position him/herself with said at least one collimated, colored light beam striking their iris.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1, and further comprising a front-surfaced mirror positioned for directing said at least one light beam from said collimating means to said two-way mirror.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1 wherein said optical collimating means comprises a transparent optical rod.
Claim 5
Dependent Claim
53 words
The apparatus of claim 3, and further comprising a first and second transparent optical rods arranged in laterally spaced relation to one another, said first and second transparent optical rods being operable to collimate and emit a first and second, colored light beams from said light source to and through said two-way mirror.
Claim 6
Dependent Claim
22 words
The apparatus of claim 4, and further comprising means for adjusting the lateral distance between said first and second transparent optical rods.
Claim 7
Dependent Claim
27 words
The apparatus of claim 5, wherein said lateral adjusting means comprises a slide block upon which one of said first and second transparent optical rods is mounted.
Claim 8
Dependent Claim
56 words
The apparatus of claim 6, and further comprising a mounting surface upon which said first and second transparent optical rods are positioned, said lateral adjusting means further including an elongated groove wherein said sliding block engages for selective movement towards and away from the other of said one of said first and second transparent optical rods.
Claim 9
Dependent Claim
37 words
The apparatus of claim 1, and further comprising a plurality of different colored color filters, and means for selectively positioning any one of said plurality of color filters between said light source and said optical collimating means.
Claim 10
Dependent Claim
28 words
The apparatus of claim 8, wherein said selective positioning means comprises a rotatable wheel upon which said plurality of color filters are placed in annularly spaced relation thereabout.
Claim 11
Dependent Claim
15 words
The apparatus of claim 9, and further comprising means for selectively, automatically rotating said wheel.
Claim 12
Dependent Claim
36 words
The apparatus of claim 9 wherein said plurality of color filters are in pairs of colors with the two color filters of a said pair of colors being located diametrically opposite one another on said wheel.
Claim 13
Independent Claim
105 words
A method of applying a color to an iris of an individual, said method comprising the steps of: a) providing a light source; b) providing a color filter; c) providing collimating means for directing a beam of light from said light source, through said color filter, and onto said iris, wherein said color filter is positioned between said light source and said collimating means; and d) providing a two-way mirror having first and second, opposite surfaces through which said light beam is directed to impinge upon the iris of an individual viewing him/herself in the surface of said two-way mirror located opposite said collimating means.
Claim 14
Independent Claim
105 words
A method of applying a color to an iris of an individual, said method comprising the steps of: a) providing a light source; b) providing a color filter; c) providing collimating means for directing a beam of light from said light source, through said color filter, and onto said iris, wherein said color filter is positioned between said light source and said collimating means; and d) providing a two-way mirror having first and second, opposite surfaces through which said light beam is directed to impinge upon the iris of an individual viewing him/herself in the surface of said two-way mirror located opposite said collimating means.
Claim 15
Dependent Claim
36 words
The method of claim 12, and further comprising a plurality of different colored color filters, and means for selectively positioning any one of said plurality of color filters in the path of said beam of light.
