Abstract
An adjustable lens includes a first lens member having a first corrugated surface, a second lens member having a second corrugated surface, and blackout regions disposed between the first and second corrugated surfaces. The first corrugated surface includes a periodic structure of alternating ridge and groove sections. The second corrugated surface includes a periodic structure of alternating ridge and groove sections. The blackout regions are positioned to block image light passing through either the ridge sections of the first lens member, or alternatively, the groove sections of the first lens member.
