Abstract
Apparatus and systems for an ophthalmic device having alignment features for a liquid filled layered stack to assemble are disclosed herein. An example apparatus may include first, second, and third optical elements arranged in a stack, with each optical element including alignment and separation features. The alignment and separation features may form a reservoir region and a dam region. The reservoir region may provide radial alignment to the first, second, and third optical elements such that an optical axis of each optical element is aligned, and the reservoir region may have a reservoir region gap formed between adjacent ones of the optical elements. The dam region, disposed radially outside of the reservoir region, may include a first dam formed due to the first and second optical elements being in contact, and a second dam formed due to the second and third optical elements being in contact, wherein the dam region determines a reservoir region gap width.
