Abstract
A method is provided for the manufacture of a holographic eye-covering article, the eye-covering article having an interference pattern corresponding to a predetermined three-dimensional object holographically prerecorded in a planar hologram layer, the interference pattern capable of being "played back" to an observer without being "played back" to said bearer. Functionality of the eye-covering article is effected in part by a light transmissive eyepiece, the eyepiece being uniaxially-curved and preferably comprising in sequence a thin web, a planar layer comprising the holographically prerecorded interference pattern, an adhesive layer, and a rigid optical substrate.
