Abstract
We demonstrated a two‐step tunable liquid crystal (LC) surface relief diffractive lens for presbyopia. The surface relief diffractive structure is fabricated by nano‐imprint lithography (NIL) roll‐to‐stage process. The LC lens is polarization‐independent with only one cholesteric liquid crystal (CLC) layer. The LC lens can be fabricated by LC one‐drop fill (ODF) process. This is useful for presbyopia vision correction. In this paper, we realized two‐step switched liquid crystal lens with optical power 0 and +2 diopters.
