An optical device includes an electrochromic layer, a plurality of electronic drivers, and a controller. The electrochromic layer includes a plurality of electrochromic regions separated from each other. The plurality of electronic drivers are arranged to electrically connect with and drive respective of the electrochromic regions. The controller is configured to control the plurality of electronic drivers to individually address each of the plurality of electrochromic regions to selectively drive some of the plurality of electrochromic regions to change light transmission of the selectively driven plurality of electrochromic regions.
