Problems solved by technology

Its shortcomings are: the polarizing film sandwiched between the two lenses is easily oxidized and corroded due to exposure to air and moisture, poor impact resistance and short life.
However, the patent document does not disclose the method of mass production of multi-layer laminated tempered glass polarized lenses

Embodiment Construction

[0018] The processing steps of the production method of the tempered glass polarizing lens of the present invention have:

[0019] Preparation of Optical Thin Sections

[0020] Roughly grind the optical glass blank with a diameter of 60-80 mm to make the convex surface reach the specified spherical radian. Then cut the material to make the concave surface reach the specified radian, and make the center thickness of the workpiece meet the specified requirements. Then finish grinding, that is, grinding the curved surface of the workpiece to make it smoother. Afterwards, it is polished to make the workpiece bright, transparent and accurately reach the specified radian and thickness.

[0021] Put the glass processing parts that reach the specified radian and thickness on the blue frame, put the batches of processed parts together with the blue frame on the upper layer of the strengthening furnace, add a cover to preheat for about half an hour, so that the temperature of the proc...

Abstract

The invention relates to a production method of toughened glass polarizing lens, belonging to the production method of spectacle lens. The inventive method comprises optically grinding a blank to reach demand arc degree and thickness, immersing into strengthen solution in batch to process chemical reinforcement, while the arc degree of front convex surface of the prepared back optical sheet is some larger than the back concave surface of the front optical sheet, heating and pressing the polarizing film into a polarizing curvature film with arc degrees, adhering the polarizing curvature film between the back concave surface of the front optical sheet and the front convex surface of the back optical sheet, removing foams, feeding into a constant-temperature solidifying furnace to be solidified in batch to prepare round lens blanks, edging and cutting the round lens blanks in the shape of mirror frame to obtain the shaped lens with triangle edge, uniformly coating adhesive on the triangle edges of the shaped lens to seal edges, laying horizontally and feeding into the constant-temperature solidifying furnace to be solidified in batch, clearing abundant adhesive materials on the edges after solidification, to obtain final product. The invention resolves the batch production problem of polarizing lens.

Description

technical field [0001] The invention relates to a production method of spectacle lenses. Background technique [0002] Traditional polarized lenses use the principle of polarized light to filter most of the radiated light, scattered light and glare to protect people's eyes. Chinese Utility Model Patent Specification CN 2386462Y discloses a patent No. ZL 99218903.9 and a technical solution titled "anti-glare glasses", which proposes to arrange a layer of polarizing film between two lenses of ordinary glasses. Its disadvantages are: the polarizing film sandwiched between the two lenses is easily oxidized and corroded due to exposure to air and moisture, has poor impact resistance and short life. For this reason, the present inventor has proposed a technical solution titled "multilayer bonded toughened glass polarizing lens", which is disclosed in Chinese Utility Model Patent Specification CN 2789797Y whose patent number is ZL 200520083653.7. The proposal proposes that the mu...
