Abstract
Ophthalmic devices and ophthalmic systems including alignment sidewalls and blend zones disposed therethrough are described. An example ophthalmic device may include a first and a second optical element having alignment sidewalls shaped to cooperatively couple. The alignment sidewall may include blend zones disposed in the sidewall shaped to transition the sidewall from a ridge to a surface of an optic zone of the optical element. The alignment sidewalls may define a cavity disposed between two coupled optical elements when the alignment sidewalls are cooperatively coupled into which a liquid crystal may be disposed. A method of assembling an ophthalmic device is described. An example method may include aligning a blend zone of a first optical element with a mating blend zone of a second optical element. The example method may further include cooperatively coupling alignment sidewalls of the first optical element and the second optical element.
