A kind of protective glasses

Abstract

The invention relates to protective spectacles. The protective spectacles are characterized by comprising a lens, a nose pad and two spectacle legs, wherein the nose pad is clamped at the concave position in the middle of the lens; the spectacle legs are clamped on the edges on two sides of the lens respectively; small holes with inclination degree are formed in the edges of the two sides of the lens respectively; a clamping groove with an upward opening is formed below each small hole; an arc-shaped area is formed at the position of the clamping groove and the small hole; and the arc-shaped area adopts a frosted surface. According to the protective spectacles, the lens adopts an integrated arc-shaped structure, the small holes with the inclination degree are formed in the edges on the two sides of the lens, and the clamping grooves are formed below the small holes and are matched with limited columns on the spectacle legs, so that disassembling / assembling of the spectacle legs and the lens is realized and the lens can be replaced according to the requirements of users. The protective spectacles are convenient, quick and firm in assembling, can solve the problem that the users cannot see things clearly due to insufficient external light, and can be widely applied to various spectacles.

Description

technical field [0001] The invention relates to a kind of protective glasses, in particular to a kind of protective glasses used for protecting eyes from small fragment damage and strong light stimulation. Background technique [0002] Most of the existing protective glasses have an integrated structure, that is, the lens is embedded on the frame, and the lens and the frame cannot be separated. Moreover, the eyeglasses of the existing protective glasses are generally made of darker color materials, which are slow to respond to external sharply changing light. When the external light is dim, the clarity of vision will be poor. Even if the existing color-changing protective glasses, when the light is dim, the lens color becomes lighter, and there is still the problem of blurred vision. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a kind of protective glasses with detachable and replaceable lenses and bet...

AI Technical Summary

Problems solved by technology

[0002] Most of the existing protective glasses have a one-piece structure, that is, the lens is embedded in the frame, and the lens and the frame cannot be separated.

Moreover, the lenses of existing protective glasses are generally made of darker-colored materials, which respond slowly to external sharply changing light. When the external light is dim, the clarity of vision will be poor.

Even the existing color-changing protective glasses, when the light is dim, only the color of the lens becomes lighter, and there is still the problem of blurred vision
