A quick-release assembly of a wearable device is disclosed and includes a locking member and a mounting base provided with an insertion cavity having an opening formed on a side of the mounting base. An accommodation cavity is provided in the mounting base and spatially connected to the insertion cavity. The locking member includes a locking portion movably disposed on the mounting base along a direction connecting the accommodation cavity and the insertion cavity and an unlocking portion connected to the locking portion. The locking member has a first state and a second state relative to the mounting base. In the first state, at least a portion of the locking portion is disposed within the insertion cavity to lock a visual member entering the insertion cavity through the opening. In the second state, the locking portion is accommodated within the accommodation cavity to release the lock of the visual member.

A glass frame structure and a wearable device having the glass frame structure are provided. The glass frame structure includes a nose pad, a glass frame body, and a limiting member. The nose pad includes one of a hook structure or a slot structure, and the glass frame body includes the other one of the hook structure or the slot structure. The limiting member is located at a first position or a second position. When the limiting member is located at the first position, the limiting member avoids the hook structure, and the hook structure is located in the slot structure and is movable in the slot structure; and when the limiting member is at the second position, the limiting member abuts against the hook structure and the hook structure is locked in the slot structure.

The present patent of invention is described as sunglasses for use in water activities which, according to its characteristics, provides sunglasses for use in water activities (1) in a specific, stand-alone structure of the universal type and based on a structuring frame (2), two sealing/protective eye cups (3) for water environments, two lenses (4) for solar environments (glare/bright light), two straps (5) to secure the glasses in place on the head, two pins (6) to hold the straps to the frame and a strap adjuster (7) integrated into a single block to attach/fix the glasses around the eyes and the head, in order to provide complete optimization of the sunglasses for use in water activities (1) in combined or stand-alone applications for protection, viewing and correction in solar and water environments, including sports practices, without any types of adjustments to the assembly.

A lens interchange mechanism for an eyewear may include a magnetic latch operatively associated with the eyewire of the eyewear, such that the a portion of the eyewire can be released, with a free end separating from another portion of the eyewire thereby forming a gap in the eyewire for the removal and installation of a lens. The magnetic latch mechanism may be further configured for easy re-latching by the application of opposing forces on the first and second eyewire portions to cause the free end to re-engage with the magnetic latch without manual actuation of the latch.
