摘要： A cell for the electronic attenuation of light suitable for use in eyewear includes spaced substrates coated with a conducting layer, and preferably a passivation layer and an alignment layer. Disposed between the substrates is a guest-host solution comprising a host material and a light-absorbing dichroic dye guest. A power circuit is provided with a power supply connected to the conducting layers. Adjustment of the power supply alters the orientation of the host material which in turn alters the orientation of the dichroic dye. Light is absorbed by the dichroic dye, depending upon its orientation without the need for polarizers.
