Claim 10:
11. A method for controlling a variable optical transmission device, comprising:
controlling a transmission parameter of a variable transmission optics of the variable optical transmission device, wherein
the method further comprises:
controlling a response duration of the variable transmission optics as a function of an initial transmission value and a target transmission value, and

the method further comprises:
controlling the response duration depending on a sign of a difference between the initial transmission value and the target transmission value, comprising:
controlling a first response duration for lowering an optical transmission of the variable transmission optics from an initial transmission value to a target transmission value, and
controlling a second response duration for increasing the optical transmission from an initial transmission value to a target transmission value, the first response duration being different from the second response duration.
