摘要:
An ophthalmic device including liquid crystal alignment features is disclosed herein. An example device may include first and second optical elements. The first optical element may include first liquid crystal alignment features formed on a first surface. The second optical element may include a first optical diffraction grating formed on a second surface, and second liquid crystal alignment features formed on the second surface. The first surface of the first optical element may face the second surface of the second optical element, and a first liquid crystal material may be disposed between the first and second surfaces of the first and second optical elements.
