## Abstract

The present disclosure relates to spectacles. The spectacles include a lens including a first portion and a second portion disposed opposite each other and a first cavity between the first portion and the second portion, a frame surrounding the lens and supporting the lens, a colored liquid disposed in the interior space, a first hydrophobic dielectric film disposed on an inner surface of the frame, a first electrode disposed between the inner surface of the frame and the first hydrophobic dielectric film, and a second electrode disposed in the interior space and in contact with the colored liquid. The frame has a second cavity defined by an inner surface of the frame. The second cavity is in communication with the first cavity to form an interior space.

## Claims

### Claim 1

Spectacles comprising:
a lens comprising a first portion and a second portion disposed opposite each other and a first cavity between the first portion and the second portion;
a frame surrounding the lens and supporting the lens, the frame having a second cavity defined by an inner surface of the frame, wherein the second cavity is in communication with the first cavity to form an interior space;
a colored liquid disposed in the interior space;
a first hydrophobic dielectric film disposed on the inner surface of the frame;
a first electrode disposed between the inner surface of the frame and the first hydrophobic dielectric film;
a second electrode disposed in the interior space formed by the first cavity of the lens and the second cavity of the frame and in contact with the colored liquid; and
a control device coupled to the first electrode and the second electrode for controlling movement of the colored liquid, wherein the control device comprises a power switch and a mode selection switch located at one of the frame and an arm of the spectacles, and a photosensitive device located on the frame, wherein either:
