Abstract: The eyeglasses includes a glasses frame and two temples. The glasses frame has two opposite ends. Each of the two temples has a front end connected pivotally to a respective one of the two opposite ends of the glasses frame. Each of the two temples have a section that is flexible so that, by applying lateral forces to the two temples, the temples are convertible between an outwardly curved state where rear ends of the two temples are spaced apart from each other at a first distance, and an inwardly curved state where the rear ends of the two temples are spaced apart from each other at a second distance that is smaller than the first distance.

Abstract: A temple unit for an eyewear includes two temples each including pivotally connected front and rear segments. The front and rear segments respectively include adjacent rear and front ends. One of the front and rear ends is formed with a protruding portion, and the other one of the front and rear ends is formed with a recess portion. The protruding portion has at least three non-coplanar first flat surfaces defining two convex corner sections. Any two adjacent ones of the first flat surfaces are connected to each other to define one of the convex corner sections. The recess portion has at least two non-coplanar second flat surfaces connected to each other to define a concave corner section engaging a selected one of the convex corner sections so as to position the rear segment relative to the front segment.

Abstract: An electrode configured for use in a direct current electrical stimulation system, which includes a control circuit configured to provide a stimulating current, includes a main body and a plurality of pin members. The main body is electrically coupled to the control circuit to receive the stimulating current therefrom and includes a base wall and a surrounding wall cooperating with the base wall to define a receiving space for receiving an electrically conductive liquid. The pin members extend from the main body, are in fluid communication with the receiving space, and permit delivery of the electrically conductive liquid to a subject when the pin members are placed in direct contact with the subject.

Abstract: A cranial electrotherapy stimulation (CES) device includes a head support, a control unit configured to provide a stimulating current, and a primary arm module. The primary arm module includes a primary arm and an electrode unit. The primary arm is pivotally connected to the head support and is longitudinally extendible. The electrode unit is disposed at the primary arm and includes an electrode that is electrically coupled to the control unit and that forms a path for transmission of the stimulating current to a stimulating point of a subject when the electrode is placed in direct contact with the stimulating point.

Abstract: An eyeglass device includes a primary frame and an auxiliary frame for receiving two primary lenses and two auxiliary lenses respectively. The primary frame includes two brow portions and two primary magnetic members disposed respectively on the two brow portions or on top edges of the two primary lenses. Each of the primary magnetic members has a magnetic surface facing upwards or downwards or rearwards. The auxiliary frame includes two brow portions and two auxiliary magnetic members disposed respectively on the two brow portions or on top edges of the two auxiliary lenses to be mutually magnetically attachable with the two primary magnetic members.

Abstract: An eyeglass device includes a primary frame having two side studs. The studs each has an opening. An auxiliary frame for disposing in front of the primary frame includes two sides each having a hook member for extending over the stud and for engaging with the opening and for securing the auxiliary frame to the primary frame. The studs each includes a magnet secured in the bottom portion of the opening and the hook members are made of magnetic material for engaging with the magnets and for securing the auxiliary frame to the primary frame.

Abstract: An eyeglass device includes a primary frame having two side studs. The studs each has a recess. An auxiliary frame for disposing in front of the primary frame includes two sides each having a clamping member for engaging with the stud and for securing the auxiliary frame to the primary frame. The clamping members each includes a channel for engaging with the stud and each includes a spring member having one or more bulges for engaging with the stud and for securing the auxiliary frame to the primary frame. The bulges may engage with the recesses of the studs.

Abstract: An eyeglass mechanism includes a primary frame having two side studs for pivotally coupling two legs. An auxiliary frame for disposing in front of the primary frame includes two sides each having an extension for engaging over the stud. The extensions each may include a magnet for engaging with another magnet engaged in the leg or with the magnetic leg and for securing the auxiliary frame to the primary frame. The extensions each includes a hook for securing to the legs without the magnets.

Abstract: An eyeglass appliance includes a primary frame having two side studs for pivotally coupling two legs. An auxiliary frame for disposing in front of the primary frame includes two sides each having an extension for engaging over the stud and the leg. The extensions each includes a magnet for engaging with another magnet engaged in the leg or with the magnetic leg and for securing the auxiliary frame to the primary frame. The extensions each includes a clamping member for securing to the legs without the magnets.
