The method further includes using the memory, obtaining a current value of a parameter, the current value being indicative of a variation of a current refractive error of the person with respect to the initial refractive error. The method additionally includes using the processing circuit, detecting a variation of a current refractive error of the person with respect to the initial refractive error based on the obtained current value of the parameter.

摘要： A wavelength tunable optical filter and a method for switching and adjusting the wavelength tunable optical filter. The optical filter includes a liquid crystal cell comprising a cholesteric liquid crystal mixture inserted between two electrodes configured to apply a voltage, the cholesteric liquid crystal mixture comprising a chiral dopant and a dual frequency liquid crystal host material, the liquid crystal cell having a reference Bragg reflection wavelength in the spectral range between 300 nm and 900 nm, and the liquid crystal cell having a first Bragg reflection wavelength, when the applied voltage is modulated at a frequency comprised in an intermediate frequency range which is above a cross-over frequency and below a high frequency limit, the first Bragg reflection wavelength being different from the reference Bragg reflection wavelength and the cholesteric liquid crystal mixture being non-scattering both in the reference Bragg reflection mode and in the first Bragg reflection mode.
