Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to prescription sunglasses and lenses for sunglasses.

[0002]

[Prior art]

 In recent years, there are many cases where sun glasses are worn when performing outdoor sports such as baseball, golf, and cycling. However, people with short-sightedness or presbyopia cannot wear only sunglasses, so they will have to wear another large sunglass over the glasses they wear all the time. However, this is very inconvenient for playing sports, and is often out of the face especially when performing intense exercise such as baseball.

On the other hand, eyeglasses in which a front frame is further attached to the front frame of the eyeglasses have been widely used. As is well known, there are many cases where people with myopia need sunglasses, or those who have presbyopia but also have myopia.In such cases, glasses for nearsighted sunglasses should be worn with a sunglasses apron frame. For example, you can wear them or wear glasses for presbyopia with a myopia lens in the apron frame.

However, spectacle frames with conventional apron frames have some problems. One of them is that the mounting structure is complicated and thus the cost is high, and the fitting state becomes loose, resulting in backlash, and the front frame is not stable. Therefore, even if the front frame of sunglasses is attached, it is inconvenient when exercising, and the glasses themselves become heavy. The eyeglass frame to which the front frame is attached has a wading that is passed over the upper end of the rim to which the lens is attached, and the design of the glasses is greatly restricted by providing the wading. Furthermore, even if the sunglasses are put on the front, the appearance is just ordinary glasses, and the image of sunglass cannot be brought.

[0005]

[Problems to be solved by the present invention]

 As described above, the conventional apron frame has the above-mentioned problems. The problems to be solved by the present invention are these problems, and it provides sunglasses which have a sangulas appearance and are equipped with prescription color lenses. We also provide a lens for sunglasses that can be cut into a desired shape.

[0006]

[Means for Solving the Problems]

 The sunglasses according to the present invention are equipped with prescription color lenses, and have the functions of both glasses worn as a daily wear and sunglasses. However, although the sunglass lens is a molded plastic lens, the whole lens is not a prescription lens, but only the central portion forms a concave lens or a convex lens. Therefore, the outer circumference of the prescription lens is a non-prescription lens, which is a curved color lens with a certain thickness.

The lens at the time of molding is in a substantially rectangular plate state, the left and right lenses are integrally formed, cut into a predetermined shape, and attached to a frame. The fixed part of the lens is an outer peripheral part with a constant thickness, and is not affected by the thickness of the lens when it is attached to the frame. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

【Example】

 FIG. 1 shows an embodiment of the sunglasses of the present invention. In the figure, 1 is a lens, 2 is a frame, and the lens 1 is formed by integrally forming left and right lens pieces 10 and 10, and is attached to the frame 2. Although both the lens pieces 10 and 10 of the lens 1 are symmetrical, the shape is different and the design as sunglasses is emphasized.

A concave portion 3 is formed between the lens pieces 10 and 10, and a nose pad cushion member 4 is attached to the bottom of the concave portion 3. The lens portion 5 has a lens portion 5 composed of a concave lens or a convex lens at the center, and the outer periphery of the lens portion 5 is an outer peripheral portion 6 having a constant thickness. The frame 2 is constructed by connecting the vines 8 on both sides of the wading 7 so that the vines 8 can be folded, and the lens 1 is attached to the wading 7.

FIG. 2 is a specific example showing a fastening structure for attaching the lens 1 to the wading 7, and a groove is formed on the lower side of the wading 7, and the lens 1 is formed in the groove. The upper edge of is fitted and screwed. In this case, a screw hole penetrates the upper edge of the lens, and the screw 9 inserted into the screw hole from the back side fixes the lens. The thickness of the lens outer peripheral portion 6 is constant over the upper edge portion, and the lens outer peripheral portion 6 is attached in a loose manner without affecting the thickness of the lens portion 5.

FIG. 3 shows a concrete example of the molded lens of the present invention. The molded lens has a substantially rectangular shape, and two lens portions 5 and 5 are integrally molded with the outer peripheral portion 6 at predetermined positions in the central portion. Although the lens portion 5 in the figure is a concave lens, it may also be a convex lens. The outer peripheral portion 6 of the molded lens thus formed is cut into an appropriate shape and attached to the frame.

The sunglasses lens 1 shown in FIG. 1 is manufactured by cutting this molded lens, and can be formed into various shapes. Of course, the shape of the frame is not particularly limited, and it is possible to use a preferable frame as sunglasses, and the lens is cut so that it can be attached to the frame. As described above, the sunglasses of the present invention are formed by cutting a molded lens into an appropriate shape and attached to the frame, and the lens is integrally molded with a prescription lens portion. Such an effect can be obtained.

[0013]

[Effect of device]

 Since the sunglasses of the present invention are equipped with a prescription lens, even a person with myopia or presbyopia can correct the visual acuity only with the sunglasses. Therefore, it is suitable for outdoor sports and can be used like ordinary glasses. In other words, unlike conventional apron-type sunglasses, its weight is light and stable, and of course it does not come off the face. The lens of the sunglasses is manufactured by cutting a molded lens into an appropriate shape. However, the above-mentioned prescription lens part is formed only in a part of the center of the lens and is formed around the lens part. The outer peripheral part has a constant thickness, which is convenient when attaching to the frame.
