Abstract: This frame component constituting a frame of eyewear is provided with: a housing having a first surface that has a first recess portion formed therein, and a first hole that opens to the first recess portion; a first device disposed in the first recess portion; and a fastening member inserted into the first hole and fixing the first device to the housing. Through this configuration, a frame component is provided which can reduce the thickness dimension of a portion in which a device is provided.

Abstract: Eyewear having: an optical module; an input unit; a sensing unit; a storage unit that stores at least conditions that change optical properties of the optical module; and a control unit that performs electric control of the optical module, in accordance with a set mode, by using electric control. The set modes include: a first mode in which the control unit electrically controls the optical module on the basis of a condition stored in the storage unit and a detection value for the sensing unit; and a second mode in which the control unit electrically controls the optical module on the basis of instructions received by the input unit. The conditions stored in the storage unit are updated on the basis of the detection value for the sensing unit when the input unit has received an instruction in the second mode.

Abstract: Provided is a sensor module that includes: a casing; a contacted part that is disposed so that at least a part thereof is exposed to the outside of the casing and that has conductivity; and a detection part that has an electrostatic capacitance type detection pad and that is disposed inside the casing. The detection part further includes a conductive plate provided so as to correspond to the detection region of the detection pad, the contacted part being electrically connected to the conductive plate. This configuration makes it possible to provide a sensor module that is highly sensitive to contact with an object, and that prevents damage to the detection pad caused by contact with the object.

Abstract: Provided are electronic eyeglasses including a power supply unit that is less likely to be unfastened and is easily attachable and detachable. A power supply unit is detachably attached to an accommodating chamber in a distal end portion of a temple. The power supply unit includes, from a front end toward a rear end, an electrical connection terminal; a first housing unit that holds a first battery, and that has a side surface having an arc shape in a plan view; a narrow portion that is connected to the arc-shaped side surface, and that has a side surface narrower than the side surface; and a second housing unit that has a side surface connected to the narrow side surface, and that hold a second battery. The accommodating chamber has a protruding portion that is elastically deformed so as to be fitted to the narrow portion of the power supply unit.

Abstract: Provided are electronic eyeglasses capable of notifying a wearer that a usage mode is switched, without obstructing a visual field of the wearer. Electronic eyeglasses include a lens that has a liquid crystal region configured to be opacified by power supply, a control unit that controls an application voltage to be supplied to the liquid crystal region, and a switching operation unit for switching the usage mode. The liquid crystal region has an area smaller than a total area of the lens. In a case where the usage mode is switched from a first mode to a second mode by an operation of the switching operation unit, the control unit controls the application voltage to be supplied to the liquid crystal region so that the liquid crystal region is opacified in a specific aspect.
