The invention relates to safety eyeglasses, in particular working safety eyeglasses or sports safety eyeglasses, having corrective eyeglass lenses for compensating defective vision, the safety eyeglasses comprising lateral protective parts (3) and eyeglass temples (5), wherein the safety eyeglasses (1) are designed as frameless eyeglasses and the corrective lenses (2) are designed as plastic lenses, which are rigidly connected to lateral protective parts (3) to be attached temporally, wherein the lateral protective parts (3) are integrally formed on the corrective lenses in an accurately fitting manner in the connection region to the corrective lenses (2) such that the curve course of the corrective lenses is reproduced by the lateral protective parts (3) in the connection region.

There is provided a novel and improved eyeglasses protection device capable of suppressing occurrence of reflected light that may enter eyes of a user of the eyeglasses protection device and thus reducing fatigue of the user, the eyeglasses protection device including: a lens surface protective part configured to protect a lens surface of eyeglasses. The lens surface protective part is equipped with a substrate film, and a micro concavo-convex structure that is formed on a surface of the substrate film, with an average period of the concavo-convex part being equal to or less than a wavelength of visible light. According to the aforementioned viewpoint of the present invention, it is possible to suppress occurrence of reflected light that may enter eyes of a user of the eyeglasses protection device because the micro concavo-convex structure is formed in the lens surface protective part of the eyeglasses protection device.

The invention relates to a spectacle temple side shield structure, wherein the two sides of the spectacle frame and the pivot joints of the temples pivotally connect to each other. Each of the temples has a detent seat corresponding with the pivot joint. The side shield device has a shielding piece arranged thereon and a detent unit provided on an inner edge of a top end of the shielding piece, wherein the detent unit has grooves correspondingly arranged on the upper and lower parts thereof, an elastic part formed between the upper and lower two corresponding grooves, and a detent protrusion protruding from the elastic part, which is latch-locked and fixed with the detent seat corresponding to each other. Therefore, users can choose different shapes and color patterns of the side shields according to their own preferences to assemble and fix them on both sides of the spectacle frame.

Disclosed is a pin-detachment guide member for fixing a side shield which is capable of easily fixing or detaching the side shield to or from glasses. The pin-detachment guide member includes an inserting protrusion (400) having a screw thread and integrally formed with one surface of the temple (A) of glasses, and a pin-detachment guide member (300) introduced into an inner space of the upper and lower wings (D and E) which overlap with each other in a vertical direction of the inserting protrusion (400), such that the pin-detachment guide member (300) is screw-coupled with the inserting protrusion (400).

A radiation filter insert is provided. The glasses filter insert includes a first filter lens and a second filter lens, each having an inner surface and an outer surface. The first and second filter lens may include an electromagnetic filter. The present invention may include a bridge connector. The bridge connector may connect the first and second filter lenses together. The bridge connector may include a curved inner edge formed to fit around a nosepiece of an eyewear. The filtering insert may include resting tabs to allow the insert to remain in position on the eyewear. The filtering insert may further include grasping tabs. The grasping tabs allow placement using the thumb and index finger of one hand. These resting and grasping tabs enables insertion and removal without displacing the eyewear. Therefore, a user may wear a pair of protective glasses and may insert the radiation filter insert in between the protective eyewear and the user, thereby shielding the user from electromagnetic energy or enabling its screening qualities.

The present invention relates to a detachable side shield structure of spectacles, which mainly a side shield unit, arranged at the pivot joint between the temple and the frame, and includes a shielding portion for shielding, a blocking bar protruded from an outer edge, and a snap portion provided on an inner edge of a top surface of the shielding portion. The snap portion has a detachable embedded portion arranged on an inner side thereof, which can correspond to a catching portion at the pivot joint of the temple and engage with each other. The temple is limited through the blocking bar and the snap portion, and the detachable embedded portion of the snap portion and the catching portion on the pivot joint form a detachable latch positioning structure, so that the side shield unit can be firmly coupled to the temple and can be disassembled and assembled as needed.

A side cover assembly of glasses frames is provided. The side cover assembly mainly includes a carrier edge portion projecting from an edge of the glasses frame and a side cover unit installed on the carrier edge portion and located under a temple. The side cover unit consists of a cover piece and a mounting flange arranged at the cover piece for being mounted in the carrier edge portion correspondingly. The cover piece is provided with locking members on an upper end and a lower end for being mounted and positioned into the glasses frame. Thereby the side cover unit is firmly connected to the glasses frame, without affecting folding and unfolding of the temple. Therefore, the side cover unit is assembled firmly and convenient to use.

Sunglasses wearable by an intended user in presence of the sun, the sunglasses comprising: a lens support wearable by the intended user and defining a sight direction relative thereto; a pair of sunglasses lenses mounted to the lens support, the sunglasses lenses having an adjustable transmittance and being selectively configurable between least and most transmitting states, wherein the sunglasses lenses transmit more visible light in the most transmitting state than in the least transmitting state; and a controller operatively coupled to the sunglasses lenses for selectively changing the transmittance, the controller being operative for changing the transmittance as a function of a sun-to-sight angle between the sun and the sight direction.

The present invention relates to a side cover fixed spectacle frame structure. The spectacle frame has two pivot seats arranged on both sides thereof. The pivot seat has an upper embedding groove and a lower embedding groove correspondingly recessed at an upper end and a lower end thereof, and a positioning hole provided on a side wall of the lower embedding groove. Each of the side covers has an assembly base correspondingly provided at one of the pivot seats, and a shielding piece extending and protruding from a lower end of the assembly base for shielding. The assembly base has a receiving groove formed on an inner side thereof, an upper embedding portion and a lower embedding portion protruding formed on an upper end and a lower end of the receiving groove, and a positioning protrusion arranged the lower embedding portion. Therefore, the side covers can be easily replaced freely.
