Abstract

The utility model discloses a tinted photochromic lens which comprises a base material, a tinted layer, a photochromic layer and a hardened layer, wherein a cellulose triacetate base material is used as the base material; the tinted layer is formed in such a way that dyes are attached to the base material; the photochromic layer is formed in such a way that a silver halide solution is attached to the tinted layer in a soaking way; and the hardened layer is formed on the photochromic layer by being treated through a hardening agent. The tinted photochromic lens disclosed by the utility model is tinted before the alterant silver halide solution is added and can meet the requirement of market development on color diversification by being blended according to colors in different proportions.

Description

The dyeing color-changing lens

Technical field

The utility model relates to the technical field of glasses, relates in particular to a kind of dyeing color-changing lens.

Background technology

develop rapidly along with social technology, people's culture, growth in the living standard, glasses are being played the part of important effect in people's sphere of life, for the patient that vision disorder is arranged, glasses can play good correcting action, select simultaneously picture frame and the eyeglass of different-style, can reach effect attractive in appearance, especially when people go on a journey, the sunglasses of wearing, both can effectively prevent ultraviolet ray burning to eyes, can reflect that again people are to the pursuit of fashion, and light-sensitive sunglasses can make according to the variation of solar flux its color change, meet strong illumination, will become colored lens, do protection, so be to be suitable for the indoor and outdoor to use simultaneously.

In the prior art, color-changing lens is to add the material such as silver halide to produce light by eyeglass and become effect in the eyeglass base material, the defective that exists like this is, the color-changing lens of producing a kind of color can only be produced in batches to add the eyeglass of silver halide base material, therefore need the quantity of input eyeglass base material more, cause the very limit of colour type.Existing sunglasses a great variety requires the color variation, the demand that traditional technique can't the satisfying the market development.

In view of this, the inventor studies and improves carrying out color-changing lens, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of dyeing color-changing lens, refers in particular to satisfy the diversified color-changing lens of color.

For achieving the above object, technical solution of the present utility model is:

A kind of dyeing color-changing lens comprises base material, dye layer, photochromic layer and hardened layer; Base material is the Triafol T base material; Dye layer is attached on base material by dyestuff and forms; Photochromic layer is attached on dye layer by immersion by silver halide solution; Hardened layer is processed by rigidizer and is formed on photochromic layer.

Further, described dyestuff by red, yellow, blue dyeing toner and baiyao water, acrinol, three kinds of dyeing liquid medicine of black powder water, is complied with different ratios by color and is modulated.

Further, hardened layer is processed forming by rigidizer TAC forced fluid.

After adopting said structure, therefore the utility model for not restriction of the color that dyes, can satisfy people to the diversified demand of color because the variable color processing of silver halide solution is carried out after lens dyeing.

Description of drawings

Fig. 1 is eyeglass composite bed schematic diagram of the present utility model.

The drawing reference numeral explanation

Triafol T base material 1 dye layer 2

Photochromic layer 3 hardened layers 4.

Embodiment

As shown in Figure 1, the utility model has disclosed a kind of dyeing color-changing lens, comprises Triafol T base material 1, dye layer 2, photochromic layer 3 and hardened layer 4; Triafol T base material 1 carries out surperficial roughening through alkali lye to be processed; Dye in the solution that modulates with the commonly used three kinds of dyeing liquid medicine of baiyao water, acrinol, black powder water of tinted lens in spectacles industry and dyeing toner again, make base material 1 dyeing form dye layer 2, can in the different ratio modulation of color, have the tinted lens of different colours with formation; The base material 1 that dyeing is good carries out immersion treatment with silver halide solution again, forms photochromic layer 3; Semi-manufacture clean, and carry out surperficial cure process with rigidizer after dehydration, produce hardened layer 4, can prevent the lens surface scratch, and rigidizer is spectacles industry TAC forced fluid commonly used, is optical grade organic silicon wear resistance coating material.

Colour-changing agent silver halide solution owing to being after eyeglass dyes, is processed eyeglass, therefore when tinted lens, can dye in advance various color, with the demand of satisfying the market to colour of lens many faceization.

These are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
