Spectacle lens adaptive adjustment procedure for varifocal lens uses local adjustment of refractive index by transparent electrodes based on eye focus measurement using reflected light

摘要

A spectacle lens (2) adaptive adjustment procedure adjusts the lens refraction coefficient locally using electro optical effects from transparent electrodes adaptively controlled by to match the eye focus by signals from a wave front or Shack Hartmann detector (3) receiving ambient or measurement light reflected from the eye (1) via the blazed lens surface (4)
