The present invention relates to a lens fixing hinge assembly of rimless glasses, and more particularly, it is applied to a rimless glasses to improve a coupling relationship between a hinged assembly and a lens coupled to a leg, greatly shortening the manufacturing process of the rimless glasses and improving post-mortem maintenance. The present invention relates to the provision of a hinged assembly that is improved to provide a back light.

Glasses are collectively used for the purpose of restoring eyesight of a person with low vision or include a pair of sunglasses that protect the eyes from strong rays in advance to prevent them from losing sight. It is largely composed of legs to support it.

Human vision is divided into normal vision, myopia, astigmatism and hyperopia;

Myopia refers to a vision in which parallel rays entering the eye form an image in front of the retina, and the near vision is hard to see, but the near vision is hard to see.

In the case of astigmatism, the eyeball, especially the cornea's spherical surface, is uneven, which means that the light does not collect at a point on the retina and cannot see the object correctly.

In the case of hyperopia, parallel rays that enter the eye form an image at the back of the retina.

In the conventional general eyeglasses, a hinge assembly having a roughly curved shape on both sides of a spectacle frame equipped with a lens is fixed by welding or the like.
