Problems solved by technology

However, due to the disadvantages of being fragile, easy to scratch, and heavy, glass spectacle lenses are gradually replaced by resin lenses, and resin lenses have also become the mainstream in the market.
PC lenses have the advantages of easy dyeing, impact resistance, and good chemical stability, but the lenses made of modified materials have weak heat resistance and are easy to deform

Abstract

The invention relates to the field of spectacle lenses, and particularly discloses a PC spectacle lens vacuum coating method which comprises the following steps: reasonably arranging a plurality of pairs of electrodes in a vacuum coating machine, respectively positioning a pair of electrodes on opposite sides, placing a spectacle lens and a support frame thereof between electric fields, applying voltage to the corresponding electrodes in the evaporation process, the electric field is used for controlling the flow direction of the steam, so that the steam can actively impact the maximum area side of the lens, and coating deposition is more uniform.

Description

technical field [0001] The invention belongs to the field of spectacle lens manufacturing, in particular to a vacuum coating method for PC spectacle lenses. Background technique [0002] Glass lenses have excellent optical properties and good light transmittance. However, glass spectacle lenses are gradually replaced by resin lenses due to their shortcomings such as brittleness, easy scratching, and heavy weight, and resin lenses have also become the mainstream in the market. PC lenses have the advantages of easy dyeing, impact resistance, and good chemical stability, but lenses made of modified materials have weak heat resistance and are easy to deform. In order to increase the strength of the spectacle lens, it is necessary to coat the surface of the spectacle lens. According to the different coating functions, the spectacle lenses can also be given different functions, such as anti-radiation, anti-blue light, anti-static and other functions. That is, the optical proper...
