Abstract
An ocular optical system including an eyewear device and a tunable light attenuator is provided. The tunable light attenuator is disposed on a light path which the eyewear device is disposed on and includes a plurality of cholesteric liquid crystal layers, a plurality of electrode layers, and a controller. Each of the cholesteric liquid crystal layers is disposed between two of the electrode layers. The controller is electrically connected to the electrode layers and configured to adjust voltages applied to the electrode layers so as to operate the cholesteric liquid crystal layers in at least two steps of light attenuation for randomly polarized light with at least one of a blue band and an ultraviolet band.
