Abstract

(57) [Summary] [Purpose] To obtain fashionable sunglasses. [Structure] A hologram film is layered on a lens surface of a predetermined shape, and a light blocking member is provided so as to project rearward from an upper edge of a rim. [Effect] The light-blocking member prevents light from entering from the back side of the sunglasses, and the three-dimensional pattern is clearly projected on the lens.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to sunglasses that are worn as holograms.

[0002]

[Prior art]

 Eyeglasses are given various decorations because fashionability is important. However, the decoration with three-dimensional shape has a drawback that the manufacturing cost is high, and the decoration with two-dimensional shape is poor in fashionability.

For this reason, a method has been considered in which a reflection type hologram film is attached to eyeglasses to give a decoration that is actually planar but stereoscopically illusion (Actual Publication No. 53-86279, etc.). . However, this method has a problem that when a film is attached to the lens of the spectacles, light is transmitted through the lens from the back side of the spectacles and the three-dimensional decoration becomes invisible.

[0004]

[Problems to be solved by the device]

 Therefore, it is an object of the present invention to realize a pair of glasses in which light from the back side of the glasses is reduced so that a three-dimensional pattern can be seen on the lens.

[0005]

[Means for Solving the Problems]

 In the present invention, in order to solve the above-mentioned problems, a lens is formed into a spherical shape or a cylindrical surface shape, a hologram-formed film is layered on the lens through a transparent adhesive, and the lens is supported. A light-shielding member that protrudes rearward is placed on the upper edge of the front rim to reduce the light from the back of the glasses and to raise the three-dimensional decoration on the lens surface.

【Example】

 Hereinafter, the present invention will be described based on embodiments.

A film 2 having a hologram formed thereon is attached to the left and right integrated plastic lenses 1. At this time, an adhesive 3 of a type that is transparent and exerts an adhesive effect at low temperature is applied to the hologram forming surface of the film 2, and the applied surface is directed to the lens 1 so that the film 2 comes to the front side of the lens 1. In this way, they are pasted together.

The lens 1 with the hologram forming film thus obtained is mounted on a plastic front body 6 having a bow shape as a whole and a rim upper rear part having a concave shape along the forehead. The front body 6 has a rear portion of the upper edge of the rim extending rearward and a light-shielding seal 62 made of a soft resin at the tip of the extending portion. After that, the temples 7 and 7 are pivoted and the sunglasses are obtained.

In this embodiment, the extended portion 61 of the rim and the light shielding seal 62 form a light shielding member. The light-shielding member prevents light from entering the back of the sunglasses and makes it easier to reveal the hologram pattern on the film. With normal use of sunglasses, it is considered that the light that passes through the sunglass from the back side to the front side comes from above the eyeglasses, so the light blocking member should be at least above the sunglasses. However, it may be considered a rare case that light coming from the side passes from the back side of the sunglasses to the front side. The temple 7 and 7 are selected so that they are connected in series in a wide state. Further, the light-shielding seal 62 in the present embodiment is positioned at the tip of the extending portion 61 of the rim which is the center of the light-shielding member, and is positioned to help block light. In consideration of the possibility that the edge of the shading member may come into contact with the forehead, a soft resin is used. However, the light-shielding member essentially has to function as an eaves, and does not necessarily have to come into contact with the forehead. Furthermore, in this embodiment, a slightly dark-colored sunglasses lens is used for the lens 1 to suppress light transmission from the back side of the sunglass to the front side so that the hologram pattern can be easily seen from the outside. However, this suppression of light transmission can also be achieved by darkening the adhesive that bonds the film to the lens.

Further, in this embodiment, the temples 7 and 7 are also decorated with holograms. This decoration is made by attaching a film to the surface of the transparent plastic decorative lens 5 having a required shape in the same manner as in the case of the lens and fitting it to the temple 7.

In addition, the adhesive 3 is applied to the back surface of the hologram forming surface of the film 2, the applied surface is attached to the lens 1, and then the hologram forming surface of the film 2 attached to the surface of the lens is hard-coated. It is also possible to provide the protective layer 4 by a coating method. This hard coat is performed to protect the holographic surface of the film, which is susceptible to scratches. Acrylic polymer-based, silicone polymer-based, or epoxy polymer-based resin can be used. The hard coating may be performed before the film is attached to the lens. The protective layer may be provided by layering a transparent resin which is solid from the beginning.

Although the first object of the present invention is to realize patterned sunglasses, the present invention can also be applied to fashion eyeglasses, goggles, underwater eyeglasses and the like that are similar to sunglasses. .
