    Abstract: Several devices for determining a distance of an object a user of an electro-active lens is looking at are presented. Once the distance is determined, the devices may alter the optical power of the electro-active lens to ensure that the object is correctly focused. Optical range finding is a possible means for carrying out this task. An active rangefinder may emit optical radiation from a transmitter directed at the object. The optical radiation may then be reflected off the object. The reflected optical radiation may then be received with an appropriate receiver. The received optical radiation may then be processed by appropriate circuitry to determine a distance to the object. A passive rangefinder works without a transmitter. Instead, an appropriate receiver receives ambient sources of light from the object. The received light may then be processed by appropriate circuitry to determine a distance to the object.

    Abstract: A low power indicator for electro-active spectacle lenses is presented in which the low power indicator is a part of a controller for the electro-active spectacle lenses or is operably connected to the controller. The low power indicator may generate a signal when the power of the power source for the electro-active spectacle lenses is low. The signal may be used by the controller or other circuitry to activate an indication to a user of the lenses that the power is low. Such an indication may be periodically activating and deactivating one of an optical power of the electro-active lenses, a vibration source, a visible light source, or an audible sound source.

    Abstract: An ophthalmic lens is presented in which the lens includes a progressive addition region and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which Is less than a user's neat viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise are reduced significantly.
