Touch, touch, swipe.

Each of the lenses in emPower!™ Eyewear features a virtually invisible layer of
liquid crystals that instantly adjusts and provides you with a near-focus zone.
Activating that zone is simple. In Manual mode, a touch of the temple triggers
the near-focus zone, while another touch turns it off. A swipe of the temple
activates the Automatic mode, so the near-focus zone turns on and off in
response to up and down movements of your head. And a portable charger
lets you power emPower! for 2–3 days with a single charge.
