Abstract: Optical elements in an optical device simulate the optical perspective of animals, reptiles, fish, insects, birds and other creatures for a human viewer. The optical elements are one or more lenses, filters, diffraction gratings, mirrors, prisms, polarizers or apertures or combinations thereof. The optical device can be a monocle, a monocular, a telescope, binoculars, goggles, a mask, a visor or a helmet. The optical element can be permanently mounted in the optical device. The optical element can be removeably mounted in the optical device. The optical element can be sequentially moved through the optical device.

Abstract: An electronic device simulates the optical perspective of animals, reptiles, fish, insects, birds and other creatures for a human viewer. The electronic device has an input sensor to collect optical images of the outside surrounding environment and convert the optical images to electronic images, an image processor to transform the electronic images from the input sensor to the appropriate creature perspective electronic images, and an output display to convert the creature perspective electronic images to creature perspective visual images to the human viewer.
