This invention relates to an electronic eyeball of doll and in particular to one comprises at least a transparent hemisphere shaped conical connex lens; a non-transparent but diaphaneity screen plate, two non-transparent, non-diaphaneity disc, a transparent film plate and a light source. The screen plate has a hole at its center attached with a color paper. The two discs also have a hole for light emitted from the light source passing through. The film plate also has a hole at its center which attached with a pupil figure. When light emitted from the light source, light will passing through the holes of the second disc, the film plate, the first disc, the screen plate and projecting onto the conical connex lens and thus the eyeball is vividly formed.
An ocular prosthetic device is provided which includes a simulated pupil that does not interfere with the intended appearance of the iris image, and further which adapts to a range of ambient lighting environments to simulate the appearance of a natural eye. An iris image is provided to reproduce the color and pattern of a natural eye. A visual display, or light source, is located behind the iris image. The visual display has a series of concentric rings to produce a size range similar to the size range between that of a dilated and contracted pupil. The iris image has a pattern of light transmissive openings to permit light from the rearwardly disposed visual display to pass through the openings. The concentric rings, when activated, are visible through the openings in the iris image, and present the appearance of a pupil of a size dependent on the number of activated rings. When the rings are not activated, that is, when they are not darkened, the iris image, which overlies the deactivated rings, is visible such that the pupil appears more contracted. A light sensor located at the center of the visual display receives light through clear areas in the center of both the iris image and the visual display. By selectively activating and darkening increasingly sized rings in the series of concentric rings, the appearance of a pupil is provided. The sclera of a natural eye is also reproduced on the prosthetic eye.

An improved artificial eye for use in dolls, stuffed animals, other toys, and the like, and for use as a prosthetic eye for human beings. The improved artificial eye consists of a sclera, a lens, and a lamina. The lens can be made of any of a variety of materials such as natural or synthetic gemstones or gemstone simulations. The lens can be used to magnify the iris and pupil images. The lamina provides images of the iris and pupil. The lamina can be a thin layer imprinted with the image of the iris and pupil and is attached to the lens such as by lamination or adhesive. Alternatively, the lamina can comprise colored glass or ceramic and is sintered onto the lens. In a second configuration, the eye additionally comprises an insert layer, which can be glass, between the lens and the lamina.
