ATTACHABLE OPTICAL ELEMENT ARRANGEMENTS AND METHODS |
摘要 |
A light attenuating optical arrangement for assembly to an eye-shielding device includes an optical element having an electronically controlled guest-host liquid crystal cell for variably attenuating transmission of light, the liquid crystal cell including first and second plastic substrates. A controller is electrically connected to the liquid crystal cell and is configured to selectively supply a voltage across the liquid crystal cell. The controller is provided with a means for electrically connecting the controller to a power source, and a means for attaching the controller to the eye-shielding device. The optical element is provided with a means for attaching an outer periphery of the optical element to a surface of a viewing lens of an eye-shielding device. |
