Nasal stent-free discoloration antifogging glasses

Abstract

The invention relates to nasal stent-free discoloration antifogging glasses. The glasses includes a W-shaped cross beam (23), the space between the two low points of the W shape is an arc, and the cross beam is supported on a nose bridge through the two low points of the W shape. Each spectacle lens consists of a resin substrate (11), a hardened storage grid film layer (12), an antifogging film layer (13) and a discoloration material film layer (14), the hardened storage grid film layer (12) is printed on the resin substrate (11) surface, the antifogging film layer (13) is dip coated outside the hardened storage grid film layer (12), and the discoloration material film layer (14) is coated outside the antifogging film layer (13). The nasal stent-free discoloration antifogging glasses provided by the invention eliminates nasal stent mounting, improves the productivity, also saves the cost, and has beautiful appearance.

Description

technical field [0001] The invention relates to the technical field of glasses, in particular to a color-changing anti-fog glasses without nose pads. Background technique [0002] At present, the metal glasses that people wear often have a pair of nose pads installed on the frame, and the frame is supported above the bridge of the nose through the nose pads. However, the installation process of each pair of nose pads is very complicated and cumbersome, which affects the production efficiency and increases the cost. [0003] In addition, when people wear glasses, due to the problem of temperature difference, fog will appear on the surface of the lens, and the white fog formed on the surface of the lens will seriously block the line of sight and affect the wearer's observation of external things. A variety of solutions have been designed to solve the problem of fog; however, the anti-fog lens itself requires a good anti-fog effect, while maintaining the original hardness of th...

[0002] At present, the metal glasses that people wear often have a pair of nose pads installed on the frame, and the frame is supported above the bridge of the nose through the nose pads. However, the installation process of each pair of nose pads is very complicated and cumbersome, which affects the production efficiency and increases the cost.

[0003] In addition, when people wear glasses, due to the problem of temperature difference, fog will appear on the surface of the lens, and the white fog formed on the surface of the lens will seriously block the line of sight and affect the wearer's observation of external things. A variety of solutions have been designed to solve the problem of fog; however, the anti-fog lens itself requires a good anti-fog effect, while maintaining the original hardness of the lens and other comprehensive performance and optical indicators cannot be reduced; how to solve this problem Contradictions, to meet customers' long-term anti-fog needs for glasses
