Problems solved by technology

Traditional glass lenses are processed with complex procedures, especially the steps of grinding and polishing, and are prone to cracking and chipping during the grinding and polishing process, which increases the production cost of the lens and reduces the quality of the lens
Moreover, the existing glass lenses are fragile, prone to water mist, and have poor blocking effect on ultraviolet rays and blue light, which obviously causes discomfort to the wearer.

Embodiment 1

[0047] A lens manufacturing process, the manufacturing process includes thermal processing and cold processing, wherein,

[0048] Described thermal processing specifically comprises the following steps:

[0049] (1) Preparation of ingredients: cleaning and drying the glass raw materials at a drying temperature of 50°C, and then cutting them into glass blocks of fixed quality;

[0050] Specifically, the cleaning of the glass raw material for the first time uses an ultrasonic cleaning machine to clean with pure water, and the rest of the cleaning can be directly cleaned with pure water. To ensure the quality of lens production, the drying of glass raw materials is to prevent moisture from affecting the glass block when weighing it, and to avoid quality errors that cause changes in the refractive index and properties of the lens, thereby affecting the quality of the lens. When weighing the glass block, it is necessary to use a scale with an accuracy of one ten-thousandth to weig...

Embodiment 2

[0110] A lens manufacturing process, the manufacturing process includes thermal processing and cold processing, wherein,

[0111] Described thermal processing specifically comprises the following steps:

[0112] (1) Preparation of ingredients: cleaning and drying the glass raw materials at a drying temperature of 80°C, and then cutting them into glass blocks of fixed quality;

[0113] Specifically, the cleaning of the glass raw material for the first time uses an ultrasonic cleaning machine to clean with pure water, and the rest of the cleaning can be directly cleaned with pure water. To ensure the quality of lens production, the drying of glass raw materials is to prevent moisture from affecting the glass block when weighing it, and to avoid quality errors that cause changes in the refractive index and properties of the lens, thereby affecting the quality of the lens. When weighing the glass block, it is necessary to use a scale with an accuracy of one ten-thousandth to weig...

Embodiment 3

[0173] A lens manufacturing process, the manufacturing process includes thermal processing and cold processing, wherein,

[0174] Described thermal processing specifically comprises the following steps:

[0175] (1) Preparation of ingredients: cleaning and drying the glass raw materials at a drying temperature of 65°C, and then cutting them into glass blocks of fixed quality;

[0176] Specifically, the cleaning of the glass raw material for the first time uses an ultrasonic cleaning machine to clean with pure water, and the rest of the cleaning can be directly cleaned with pure water. To ensure the quality of lens production, the drying of glass raw materials is to prevent moisture from affecting the glass block when weighing it, and to avoid quality errors that cause changes in the refractive index and properties of the lens, thereby affecting the quality of the lens. When weighing the glass block, it is necessary to use a scale with an accuracy of one ten-thousandth to weig...

Abstract

The invention discloses a lens manufacturing process which comprises the steps of hot processing and cold processing, wherein the hot processing specifically comprises the following steps: ingredientpreparation, mold preparation, glass melting treatment, automatic compressionmolding, annealing treatment and lens blank testing; and the cold processing comprises the steps oflens grinding and polishing, lens cleaning, lens coating and lens testing. The lens manufacturing process provided by the invention is not only simple in process, but also highly intelligent, errors of traditional manual manufacturing can be avoided, the cost of lens production can be reduced, and the production efficiency can be improved. Moreover, a lens manufactured by the lens manufacturing process provided by the invention is not only good in quality, but also capable of alleviating defects of fragility and easy fogging, has effects of preventing blue light and ultraviolet light, and improves the comfort of a lens wearer.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a lens manufacturing process. Background technique [0002] The main raw material of glass lenses is optical glass, which has superior optical properties, is not easy to scratch, and has a high refractive index. The light transmittance and mechanical and chemical properties of glass lenses are relatively good, with a constant refractive index and stable physical and chemical properties. Traditional glass lenses require complex procedures, especially grinding and polishing, and are prone to breakage and chipping during the grinding and polishing process, which increases the production cost of the lens and reduces the quality of the lens. Moreover, the existing glass lenses are fragile, prone to water mist, and have poor blocking effect on ultraviolet rays and blue light, which obviously causes discomfort to the wearer. Contents of the invention [0003] The invention provides a ...
