What distinguishes e-Vision’s Smart Focus Optics from other liquid crystal lens-based technologies is due, in part, to the placement of electrodes, which is essential to achieve desired outcomes. Within the liquid crystal layer, there are both concentric ring electrodes as well as ‘floating’ electrodes.  When the electric profile is applied to a specific region, the floating electrodes help fill the gaps between the concentric electrodes.  The floating electrode design greatly improves lens performance, particularly by eliminating the scattering due to the gaps. The floating electrodes also increase the phase sampling across the lens plane, which further improves efficiency. In addition to its proprietary electrode configuration, Smart Vision Optics technology achieves significantly greater power efficiency compared to previous electronic lens designs. This allows e-Vision lenses to maintain a charge while continually modulating the lens optical power.

Tunability: Rather than being limited to a lens that simply turns on- or- off, the Smart Vision Optics technology is analog adjustable, allowing an infinitely adjustable focus at any power desired ranging between the maximum plus and maximum minus optical power.

Wavefront Shape Outcomes: Unlike fixed lenses which provide a set prescription, wavefront shapes created with Smart Focus Optics technology are highly customizable. E-vision lenses are electrically-modulated lenses that can create virtually any desired wavefront due to the way in which energy can be applied to very specific regions of the lens to correct irregular shapes, including higher-order aberrations
