This eyewear is provided with: a frame; a lens which is supported by the frame, and which includes an optical characteristic varying portion having an optical characteristic which is varied by means of electric control; a communication portion for receiving information from an external terminal; and a control portion for controlling the optical characteristic varying portion on the basis of the information received from the external terminal.

Eyewear, and non-transitory computer-readable recording medium

This lens is provided with: a transparent first substrate; a transparent second substrate provided facing the first substrate in the thickness direction of the first substrate; a first optical characteristic varying portion which is provided between the first substrate and the second substrate, and which has an optical characteristic which is varied by means of electric control; and a second optical characteristic varying portion which is provided between the first substrate and the second substrate, is provided displaced with respect to the first optical characteristic varying portion in the thickness direction, and which has a optical characteristic which is varied by means of electric control.

Lens, lens blank, and eyewear

Spectacles

This lens unit comprises: a lens having a liquid crystal lens; a rim part that covers the peripheral edge section of the lens; a control unit that controls the liquid crystal lens; a conductive part that electrically connects the control unit and an electrode end section of the liquid crystal lens which is exposed at the peripheral edge section of the lens, and that is disposed between the rim part and the peripheral edge section of the lens; and a knob part that protrudes from the lens or rim part.

Lens unit

A lens includes: a substrate that includes a diffraction region where a plurality of protruding strips are coaxially and alternately formed. The diffraction region includes a first diffraction region and a second diffraction region that is located in at least a part of a region different from the first diffraction region. The second diffraction region includes: groove spaces lying between adjacent ones of the protruding strips with one another; and a communication space communicating between adjacent ones of the groove spaces with one another.

The lens comprises: a first transparent substrate that includes a diffraction region in which a plurality of convex strips and groove sections are formed in alternation in concentric circles; a second transparent substrate that faces the first transparent substrate; a liquid crystal layer disposed in a space present between the diffraction region and the second transparent substrate; and a first transparent electrode and a second transparent electrode that impress a voltage on the liquid crystal layer. The diffraction region comprises a first diffraction region and a second diffraction region that is disposed in at least part of a portion different from the first diffraction region. The space comprises: groove-shaped spaces present between the groove sections and the second transparent substrate; and a communicating space disposed between at least part of the convex shapes of the second diffraction region and the second transparent substrate, and communicating between neighboring groove-shaped spaces.
