Apparatus for making plastic molds

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.
