An automatic fast focusing infinitely variable focal power Lens Unit, to supply the infinitely variable focal power as required. The Lens Unit consists of two lenses, one of which is stationary, being connected to an eyeglass frame or other optical products with the outer lens moving in connection with precisely constructed joints fastened to the inner stationery lens. The outer lens is automatically adjusted by Precision Proportional Solenoids. A Radar-sending and receiving unit supplies the signal for controlling the movement of the outer lens, that takes place to supply the infinitely variable focal power. The Lens Unit is covered around on the periphery by a C-shaped Ring reservoir containing a clear refractive liquid to flow throughout the entire Lens Unit as the outer lens moves outwardly and then back inward to its starting point and zero mark, for value of focal power. The construction described herein is to give precision and uniform results repeatedly, for people who need bifocals, trifocals, etc., and for people who need glasses to read because of farsightedness due to age, etc. The eyeglass product described in this invention is designed to help the visually impaired as well as those who need reading glasses to give the best obtainable results possible. The Lens Units are also readily adapted to sighting scopes, bombsights, etc. either for civilian or military use. .
