emPower eyeglasses have the same look, weight and feel of regular eyewear but they have microchip, micro-accelerometers, and miniature batteries hidden inside the temples of the eyeglass frames. The transparent liquid crystal layer in each lens is able to electronically change and activate the near focus lens only when needed with no moving parts and all without making a sound. emPower allows for seeing clearly at all distances; far, near and in between. emPower is shock resistant and waterproof. One charge of the battery allows for two to three days of operation.
