Abstract

The utility model discloses a lens with progressive coloring, which comprises a dark color layer, a gradient layer and a colorless layer, wherein the height ratio of the dark color layer and the colorless layer are respectively (6-7):(4-3),and the height of the gradient layer is 7-13 mm. The lens with the progressive dyeing shortens the height ratio of the dark color layer and the colorless layer and reduces the gradient layer; after the lens is cut, the dark color layer, the gradient layer and the colorless layer can be uniformly distributed; a dyed part and a part without being dyed of the lens can be obviously distinguished; and after the lens is framed, the progressive transition of colors is obvious, the use effect is ideal, and the appearance effect is good.

Description

A kind of dyeing progressive lenses

Technical field

The utility model relates to a kind of dyeing progressive lenses.

Background technology

So-called dyeing progressive lenses, comprise dark layer, graded bedding (color gradual change) and colorless layer from top to bottom, wherein, the dark layer of top is mainly used in to be faced, can block high light, play the effect of sunglasses, the colorless layer of below is mainly used in to be overlooked, and plays the luminous efficacy of glasses itself, middle graded bedding then is the effect that plays color transition, so, can have multiple efficacies, therefore be subjected to user's favor with a pair of glasses.

But in the prior art, no matter the dyeing progressive lenses is disk (as shown in Figure 1) or Cam plate (as shown in Figure 2), the aspect ratio of dark layer 10 and colorless layer 30 all is 8: 2, and the height of graded bedding 20 is then between 20～25 millimeters.Dark layer 10 is too big, graded bedding 20 is big too, after making eyeglass cut out shape, easily because cut out the size of shape and cut out the shape deviation, and become full dark color, or have only dark layer 10 and graded bedding 20, or have only graded bedding 20 and colorless layer 30, and also be that graded bedding 20 accounts for many and dark layer 10 and colorless layer 30 account for seldom even cut out shape between two parties, promptly cut out eyeglass coloured portions after the shape with the coloured portions differentiation is not obvious, therefore, when existing dyeing progressive lenses framed up, the color gradual transition was not obvious, used effect undesirable, appearance is also poor, is further improved really.

The utility model content

The purpose of this utility model is to provide a kind of color gradual transition obvious, uses effect good, the dyeing progressive lenses of appearance.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of dyeing progressive lenses is divided into dark layer, graded bedding and colorless layer from top to bottom, and wherein, the aspect ratio of dark layer and colorless layer all is (6～7): (4～3), and the height of graded bedding is 7～13 millimeters.

The height of described graded bedding is 10 millimeters.

Described eyeglass is concave lens, hyperopic lens or plano lens.

Described eyeglass is disk, Cam plate or goggles.

After adopting such scheme, the utility model has dwindled the aspect ratio of dark layer and colorless layer, dwindled graded bedding, eyeglass can make dark layer, graded bedding and colorless layer be evenly distributed after cutting out shape, and the eyeglass coloured portions is with the coloured portions differentiation is unobvious, when such eyeglass frames up, the color gradual transition is obvious, uses the effect ideal, and appearance might as well.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Fig. 2 is the structural representation of existing dyeing progressive lenses (Cam plate);

Fig. 3 is the structural representation of the utility model (disk);

Fig. 4 is the structural representation of the utility model (Cam plate);

Fig. 5 is the structural representation of the utility model (goggles).

Embodiment

To shown in Figure 5, is three kinds of embodiment of the present utility model as Fig. 3.

A kind of dyeing progressive lenses that the utility model discloses, be divided into dark layer 1, graded bedding 2 and colorless layer 3 from top to bottom, the aspect ratio of dark layer 1 and colorless layer 3 all is (6～7): (4～3), and the height of graded bedding 2 is 7～13 millimeters, and the optimum height of graded bedding 2 is 10 millimeters.This eyeglass is concave lens, hyperopic lens or plano lens.

Wherein, eyeglass shown in Figure 3 is a disk, and the height of dark layer 1 is 40 millimeters, and the height of graded bedding 2 is 10 millimeters, and the height of colorless layer 3 is 25 millimeters; Eyeglass shown in Figure 4 is a Cam plate, and the height of dark layer 1 is 34 millimeters, and the height of graded bedding 2 is 10 millimeters, and the height of colorless layer 3 is 21 millimeters; Eyeglass shown in Figure 5 is a goggles, and the height of dark layer 1 is 37 millimeters, and the height of graded bedding 2 is 10 millimeters, and the height of colorless layer 3 is 23 millimeters.

Below only being three preferred embodiments of the present utility model, is not the qualification to protection domain of the present utility model, and all equivalent variations of doing according to the mentality of designing of this case all fall into the protection domain of this case.
