10. Eyeglasses, comprising:
-
a frame; a pair of lenses mounted on said frame, said lenses including a liquid crystal device having a variable transparency; voltage generator means connected to said lenses, said voltage generator means for converting luminous energy incident on said lenses into electrical energy; an infrared sensor for detecting an IR signal; switching means which connects said liquid crystal device of said lenses alternatively to said infrared sensor and to said voltage generator, whereby each lens, upon connection to said infrared sensor assumes a condition of transparency or of darkness alternatively, in response to the infrared signal detected by said sensor, and each lens, upon connection to said voltage generator is controlled by a voltage signal generated by said voltage generator as a function of the incident luminous energy.

11. Eyeglasses, comprising:
-
a frame; a pair of lenses mounted on said frame, said lenses including a liquid crystal device having a variable transparency; voltage generator means connected to said lenses, said voltage generator means for converting luminous energy incident on said lenses into electrical energy, said lenses being subdivided into a plurality of adjacent fields, each field having the form of a strip extending along a width of the relevant lens, each field being constituted by a pixel realized with a liquid crystal device, said pixels being connected to one another and being connected to said voltage generator in such a manner that each pixel is supplied with a different voltage as compared with adjacent pixels in order to obtain a gradual shading of said lenses. - View Dependent Claims (12, 13, 14, 15)
