E-Vision Announces Demo for Liquid Crystal Electronic Contact Lens

Wednesday, April 11 2018 | 00 h 00 min | News, Press Release

E-Vision™ Smart Optics has announced the successful completion of a prototype version of their electronic contact lens platform device to demonstrate the ability to electronically change diopters in real time to prospective licensing partners.

The Electronic Contact Lenses will offer features including onboard power/control, remote setting and activation, dimensions that fit within current contact lens size requirements, and up to four diopters of control, or more, that can be switched in 50 milliseconds.

Sandwiched between three thin layers of polymer are two layers of liquid crystal, 8 microns thick.  In the unpowered mode, the liquid crystal molecules are in their relaxed state and provide no  optical power. When a small voltage is applied, the liquid crystal molecules begin to change their optical properties resulting in focus changes in the lens.

All power, electronics, optics and communication components will be inside of the contact lens. The power source will provide energy for a full day’s use and be recharged wirelessly when removed from the user’s eye overnight.
