Description

Combined multifunctional children glasses

Technical Field

The utility model relates to the technical field of glasses, in particular to a pair of combined multifunctional children glasses.

Background

The glasses mainly comprise optical glasses, goggles, sunglasses, swimming glasses and the like. The optical glasses include myopia glasses, hyperopia glasses, presbyopia glasses and astigmatic glasses, and have the function of correcting the vision. Goggles, sunglasses, swim glasses, and the like, provide various protection to the eyes. With the development of science and technology, there are also special glasses for watching 3D stereoscopic images or virtual real images. Typically, eyeglasses consist of a lens and a frame. The mirror holder adopts the screw with picture frame and mirror foot pin joint together, and the lens is assembled in the picture frame of mirror holder. The eyewear also has a nose pad for supporting over the bridge of the nose.

Currently, as electronic products are increased, the burden of learning is increased, more and more patients with myopia, hyperopia and amblyopia of children are required, and the demand of children's glasses is increased. Ordinary adult's glasses are not suitable for children to wear because of the many metal components. For example, the nose pad is formed by combining a metal frame and a soft pad, the metal frame is exposed, the metal frame is locked on the glasses frame by screws, the soft pad is also locked on the metal frame by screws, the screws are easily fixed and loosened, even the soft pad and the metal frame fall off, the structure is not firm, the normal use of the glasses is directly influenced, and the adjustment is inconvenient. For another example, the temple is pivoted on the frame by screws, the opening and closing angle of the temple is fixed, only two states of complete opening and complete folding and unfolding are needed, for wearers with different head types and wide heads, the glasses can be worn only by adjusting the frame and the temple, the adjusting difficulty is very high, the adjusted temple cannot be clamped on two sides of the head well, the wearing and positioning of the glasses can be realized only by hooking the temple and the ear and supporting the middle beam and the nose of the frame, and the glasses are not suitable for active and active children.

Therefore, the inventor specially develops the combined multifunctional glasses to be suitable for children to wear.
