Accordingly, it goes without saying that the first element mentioned below may be the second element within the spirit of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 is a perspective view of the high-resolution lens unit according to an embodiment of the present invention, FIG. 2 is a front view of the high-resolution lens unit of FIG. 1, and FIG. 3 is the high-resolution lens unit of FIG. 4 is a cross-sectional view of the high-resolution lens unit of FIG. 1 taken along line B-B'.

1 to 4, the high-resolution lens unit includes an external lens 100 having a curved shape, an anti-fogging layer 200 attached to the external lens 100 and having a curved shape, and the external lens ( 100) is interposed between the anti-fog layer 200 and adheres the external lens 100 and the anti-fog layer 200, and includes an adhesive layer 50 including OCA (Optical Clear Adhesive), wherein the external lens includes It is characterized in that it has a positive (+) frequency.

The lens unit and lens units according to various embodiments to be described below will be understood as a lens unit mounted on goggles to be described later, and the goggles to which the lens unit is mounted or coupled may be snow goggles, ski goggles, cycle goggles, etc. , but is not limited thereto, and may be used without limitation in various sports goggles such as goggles used for sports activities such as running and walking.

On the other hand, the external lens 100 is located at the outermost part of the lens unit and performs a function of protecting the user's eyes from wind, ultraviolet rays, snow, rain, dust, etc. from the outside. As a non-limiting example, the external lens 100 may have high visible light transmittance and excellent UV protection for securing a clear view, etc. It may be made of a material such as carbonate (PolyCarbonate: PC). In addition, if necessary, UV blocking treatment, anti-glare treatment, and anti-fog treatment may be applied. The external lens 100 may be manufactured by injection.

On the other hand, the anti-fogging layer 200 may be formed of a soft material capable of imparting anti-fog performance (anti-fog) together with processability, and for this purpose, as a non-limiting example, a triacetyl cellulose (TAC) film , may be composed of a cellulose propionate (CP) film, etc., but preferably a CAP (Cellulose Acetate Propionate) film in consideration of the optimized refractive index and water absorption performance. The antifogging layer 200 may contain a small amount of a plasticizer in order to impart ductility to the CAP (Cellulose Acetate Propionate) film.

For example, the antifogging layer 200 may be manufactured by chemically etching the cellulose acetate propionate (CAP) film. A microporous structure may be formed through chemical etching, and thus moisture between the user's eyeball and the lens unit may be partially retained to improve hygroscopicity.

In the conventional case, in order to prevent fogging, a method of applying AF (AntiFog) to the surface of a prime lens was used. However, the method of applying AF to the surface of a prime lens has a problem in that the amount of water that can be treated is small, so that a large amount of water still causes fogging.

In the case of the present invention, a separate antifogging layer 200 is formed and directly attached to the external lens 100 through the adhesive layer 50, thereby maximizing the antifogging function (Antifog) while hardly increasing the overall thickness of the goggles. can do.

To this end, the anti-fog layer 200 may be characterized in that the thickness ranges from 0.4 mm to 0.9 mm. When the thickness of the anti-fog layer 200 is less than 0.4 mm, the rigidity is weak, so that even a small bending may occur, and when the thickness is more than 0.9 mm, it may be difficult to form a curved surface. In addition, the thickness (T1) of the adhesive layer 50 may be characterized in that the thickness range of 0.04mm to 0.06mm. In the above range, light introduced from the outside may be transmitted almost as it is without a change in refractive index.

In the lens unit of the present invention, the external lens 100 and the anti-fogging layer 200 include a curved shape in order to give design aesthetics. In the conventional case, when the goggles are formed with only one lens including a curved shape, a separate dioptric power is not provided. On the other hand, the inventor of the present invention confirms that the negative power is generated in the anti-fog layer 200 when directly combining them while including the anti-fog layer on the lens in order to give design aesthetics to the lens unit. By this, it was confirmed that the negative power of the overall lens unit occurred and the object was distorted to be visually recognized. It was offset so that the dioptric power of the lens unit as a whole was lost. Accordingly, it was prevented that the object was recognized as being distorted.

On the other hand, FIG. 5 is an exploded view schematically showing the direction in which light is incident and progresses in each of the components of the high-resolution lens unit according to an embodiment of the present invention, and in FIG. 6, the external lens and the anti-fog layer of FIG. A diagram schematically showing the direction in which light is incident and proceeds in the coupled state is shown. That is, in FIGS. 5 and 6, each component is decomposed and displayed to explain the directionality of light passing through each of these components in order to show the change in refraction of light by the external lens 100 and the anti-fog layer 200 of the present invention. and combined, it is indicated.

5 and 6, the high-resolution lens unit of the present invention will be described in more detail. As shown in FIG. 5, the external lens 100 of the present invention has a positive power, so that external light is introduced As the light is refracted in the central direction, it can proceed. In addition, the anti-fog layer 200 has a negative power, so that the incoming light can be refracted again from the center toward both ends, and eventually the external lens 100 and the anti-fog layer 200 are laminated. As shown in FIG. 6 , the light that was initially introduced has the same directionality as it is and is transmitted to the user's eyes, thereby preventing the object from being distorted and recognized.

In the case of the anti-fog layer 200, there is no separate power, but the inventor of the present invention confirms that the negative power occurs when bending the anti-fog layer 200 to produce a curved shape, and to compensate for this For this, a positive (+) power was applied to the external lens 100 to offset this.

The shape of the curved surface of the external lens 100 and the antifogging layer 200 may be characterized in that the curved surface is formed in the left and right direction from the left eye of the user to the right eye direction. In this case, since the negative power is generated in the left and right direction by the curved shape of the anti-fog layer 200 in the left and right directions, the external lens 100 has a positive (+) in the left and right directions The frequency can be removed by giving a degree to offset it.

Referring back to FIG. 3, the outer lens 100 has the thickest thickness P1 at the center, and the thickness gradually decreases toward both ends in the left and right direction, so that the thickness P2 at both ends has the thinnest structure. have. Thereby, it is possible to optically increase the focal length. In addition, the antifogging layer 200 may have the same thickness P3 at the center and the thickness P4 at both ends. That is, the thickness of the anti-fog layer 200 may be all uniform.

Meanwhile, as described above, the external lens 100 may be made of a polycarbonate (PC) material, and may be characterized in that all portions of the external lens 100 have the same density. In addition, it may be characterized in that the outer and inner surfaces of the external lens have a positive (+) refractive index. That is, the overall density of the external lens 100 is the same, and the focal length is changed by changing the thickness of the center and both ends of the external lens 100 or by changing the curvature of the external lens 100 to increase the dioptric power. It can be adjusted by the power of (+). For this purpose, for example, the outer and inner surfaces of the external lens 100 may have a positive (+) refractive index, which is the total refractive index of light propagating from the outer surface of the external lens 100 to the inner surface. It will be understood that this becomes a positive (+) refractive index.

In other words, for example, both the outer and inner surfaces of the external lens 100 may be convex in the outward (outward) direction with respect to the user. The side is shaped like a convex lens in the direction in which the light is incident, and the light is collected as the light passes through. can be Therefore, based on the user's eyeball, the light passes through the outer surface of the outer lens 100 and the light is collected up to the center of the outer lens 100, and the light passes through the center of the outer lens 100 again. It can spread gradually while facing the side. In the present invention, the meaning of "having a positive (+) refractive index on the outer and inner surfaces of the external lens" means that light is incident from the outer surface of the external lens 100 as above. It will be understood that the overall refractive index passing through the inner surface and exiting (ie, the total refractive index) has a positive refractive index.

Meanwhile, FIG. 7 is a cross-sectional view of the high-resolution lens unit of FIG. 1 taken along line B-B' according to another embodiment.

7, the shape of the curved surface of the external lens 101 and the anti-fog layer 201 is characterized in that the curved surface is formed in the vertical direction perpendicular to the left and right direction from the user's left eye to the right eye direction. can In this case, the negative power generated by the spherical refraction of the antifogging layer 201 in the lens unit may also occur in the vertical direction, and by giving a positive power in the vertical direction of the external lens 101 , it is possible to offset the frequency caused by the overall spherical refraction to prevent objects from being distorted or not being recognized well.

Meanwhile, FIG. 8 is a perspective view of a high-resolution lens unit according to another embodiment of the present invention, and FIG. 9 is a front view of the high-resolution unit of FIG. 8 .

8 and 9 , the antifogging layer 202 includes a viewing area A that is recognized by the user's eyes and a non-viewing area B that is not viewed by the user's eyes, and protrudes from the non-view area B It may be characterized in that it includes a plurality of adhesion auxiliary parts (212, 222) spaced apart from each other on a vertical line. The viewing area (A) means an area visible to the user when the user wears the goggles, and the non-viewing area (B) is an area not visible to the user or coupled to the frame of the goggles, for example. can mean In the drawing, the viewing area (A) and the non-viewing area (B) are set in the left-to-bottom direction, but the present invention is not limited thereto. It is an area A, and a part of the upper end or left and right directions may be the non-viewing area B.

The adhesive auxiliary parts 212 and 222 may be formed to extend from the visual field weak A of the anti-fog layer 202 and protrude apart from each other in the non-viewing area B. As the adhesive auxiliary parts 212 and 222 protrude apart from each other, the area exposed to the outside can be widened, thereby preventing the anti-fogging layer 202 from being separated from the external lens 102 by external factors. Compared to the case where the anti-fog layer 202 is composed of a simple straight edge, as shown in FIGS. 8 and 9 , the adhesion auxiliary parts 212 and 222 are formed to form a plurality of protruding parts, thereby effectively preventing separation caused by external factors. can do. Since the adhesive auxiliary parts 212 and 222 are formed in the non-viewing area B, they do not affect the user's view. In the above description, the meaning that the auxiliary adhesion parts 212 and 222 protrude from each other and are spaced apart from each other may be interpreted as meaning that they are spaced apart from each other on the surface formed by the external lens 102 .

The portion where the external lens 102 and the anti-fog layer 202 are substantially separated may occur as foreign substances are introduced in the outermost direction. Separation of the anti-fogging layer 202 can be minimized by maintaining adhesion and bonding by other parts even if a foreign material is introduced into the air and is separated.

In addition, although not shown separately, the adhesion auxiliary parts 212 and 222 may be formed in the vertical direction as needed, unlike FIGS. 8 and 9 .

Meanwhile, FIG. 10 is a perspective view of a high-resolution lens unit according to another embodiment of the present invention, and FIG. 11 is a front view of the high-resolution unit of FIG. 10 . In addition, FIG. 12 is an enlarged view showing an enlarged portion C in the front view of FIG. 11 .

10 to 12 , the auxiliary adhesion portion of the antifogging layer 224 includes first auxiliary adhesion portions 214-A and 224-A protruding by a first length H4, and the first length H1. and a second auxiliary adhesion part 214-B protruding by a second length H2, which is longer than that, and the first auxiliary adhesion part 214-A and the second auxiliary adhesion part 214-B are connected to each other It may be characterized in that they are alternately arranged. By making the lengths of the first auxiliary adhesion parts 214-A and 224-A and the second adhesion auxiliary parts 214-B and 224-B different, the anti-fogging layer 224 is separated from the external lens 104 This phenomenon can be prevented more effectively. That is, even if any one of the first auxiliary adhesion part 214-A or the second adhesion auxiliary part 214-B is separated from or separated from the external lens 104 by any factor, it minimizes the influence on the adhesion of other parts to prevent fogging. Separation of (204) can be prevented to the maximum.

The first auxiliary adhesion parts 214-A and 224-A are formed by extending in a direction perpendicular to the direction in which the first auxiliary adhesion parts 214-A and 224-A protrude on the horizontal surface of the anti-fog layer 204. Including a first adhesive wing, the second adhesion auxiliary parts (214-B, 224-B) is the direction in which the second adhesive auxiliary parts (214-B, 224-B) protrude on the horizontal plane of the anti-fog layer (204) It may include a second adhesive wings formed extending in a direction perpendicular to, the first adhesive wings and the second adhesive wings may not overlap each other on the surface of the external lens (104).

For example, the first adhesive wing and the second adhesive wing are first adhesive auxiliary parts 214-A and 224-A and second adhesive auxiliary parts 214-B and 224-B on the horizontal plane of the external lens 104. It may be protruded while extending vertically in the vertical direction, which is a direction perpendicular to the left and right directions 214-A and 214-B are the left direction, and 224-A and 224-B are the right direction, which is the first protruding direction. The part where the external lens 104 and the antifogging layer 204 are substantially separated may occur as foreign substances are introduced in the outermost direction. By forming the first and second adhesive wings, the external lens 104 and the combined area of the outermost layer of the anti-fog layer 204 may be increased.

On the other hand, referring to FIG. 12 , the first adhesive wing and the second adhesive wing are first adhesive auxiliary parts 214-A and 224-A and second adhesive auxiliary parts 214-B and 224-B, respectively. It may be formed to extend in both directions perpendicular to the direction. Therefore, it may be in a form such as a kind of T-shape. That is, for example, the width (D2) of the outermost second adhesive wing may be formed to be wider than the width (D1) of the portion from which the second adhesion auxiliary part (214-B) first protrudes. Thereby, it is possible to maximize the separation between the outer lens 104 and the anti-fog layer 204 by widening the area coupled to each other in the outermost portion.

In addition, the first and second adhesive wings do not overlap each other on the surface of the external lens 104, but may overlap each other on an imaginary straight line in the left and right directions. That is, a portion of the first adhesive wings formed by the short first adhesive auxiliary portion 214-A may exist at a position overlapping on the horizontal line between the adjacent second adhesive wings. In this case, the second adhesive wing primarily blocks foreign matter from the outside, and secondarily, the first adhesive wing maintains the adhesive force from the inside, thereby further improving durability.
