Automatic-signal-selecting is provided for controlling which output is supplied from a switch, i. In the pattern-interspersed region, the dummy patterns are arranged in a manner that at least one dummy pattern exists in a scan target range of a mask pattern defect inspecting apparatus. The column mux logic uses MEMS contact-switch elements that have additional contact electrodes that touch and make electrical connection when the MEMS switch is closed, but do not touch and isolate the contact electrodes from each other when the MEMS switch is open. The lens has a prescription based on a wave front analysis of the wearer’s eye and the lens can further be modified to fit within an eyeglass frame.
