Bi-focals have been around since the dawn of mankind and haven’t changed much since they were invented by Benjamin Franklin. However a company called PixelOptics has gone ahead and re-invented them with state of the art technology. Their new emPower line of glass lenses change prescription faster than in the blink of an eye. There are no moving parts and the change is virtually instantaneous. An invisible electronic add zone located about a half inch below the center of each lens changes the prescription in that portion of the lens so that vision goes from being clear at fingertip distance to clear up-close for reading. When the electronic add zone is activated, it will blink on and when deactivated, it will blink off. emPower! lenses have two modes of operation: automatic and manual. In automatic mode, the switch between full or partial reading prescription depends on where the wearer looks. The wearer looks down and the full reading prescription turns on; the wearer looks straight ahead and the emPower! lens returns to the partial reading prescription in manual mode the person decides when to adjust the glasses to a reading prescription. Control of the manual mode as well as switching to automatic mode is performed on the right temple of the eyeglasses. Manual mode is the default mode and activating the full reading prescription (turning emPower! ON) simply requires a touch of a finger. Switching to partial reading prescription (turning emPower! OFF) simply requires another touch of the finger. A swipe in either direction activates the automatic mode. Once activated emPower! automatically detects whether the viewer is looking up or down. These new glasses will be available in April for the low price of $1200.00. For more information on PixelOptics emPower glasses please visit:
