Abstract

PURPOSE:To allow the wearing of the overlaying spectacles in a stable state from above the already worn spectacles without having an odd feel by cooperatively integrating an outer front frame, forehead plate and outer temples, thereby forming the overlaying spectacles. CONSTITUTION:The forehead plate 1 which can be stably imposed in a nonslip state on the upper edge part of the front line of the already worn spectacles and has an antislip body 21 consisting of a soft synthetic resin material having a large coefft. of friction in the end edge part thereof and the longitudinal outer temples 3 which extend to the rear head of a wearer and can embrace the rear head part are provided. The overlaying spectacles are overlap worn on the already worn spectacles from above without the odd feel and this state is maintained by relatively holding the spectacles always in the ideal positional relations with the lenses of the already worn spectacles. In addition, the comfortable wearing is possible without allowing the wearer to feel the slightest heavy loading feel in the nose contact parts.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides overlay glasses that can be smartly worn over existing eyeglasses, and more specifically, overlay glasses that can be worn over existing eyeglasses, and more specifically, that can cover the lenses of existing eyeglasses so that they cannot be seen. The present invention relates to overlaying eyeglasses that can be stacked stably and smartly by maintaining a constant distance between them and existing eyeglass lenses.

[Conventional technology and technical issues to be solved] People who regularly wear glasses due to other reasons such as refractive errors (myopia, farsightedness, astigmatism, presbyopia) suffer from glare from direct sunlight or reflected light ( When you need to protect your eyes from damage caused by glare (glare) or harmful rays, or when you need to see underwater conditions through the shining water surface, such as when fishing, you should wear them in front of the prescription lenses of your existing glasses. Do you install photochromic lenses (e.g., polarized lenses, colored lenses, photochromic lenses, etc.) using a lens frame with an apron-type clip mechanism, or add photochromic function to prescription lenses that you already wear? The only solution was to do something like this. However, people who regularly wear vision correction glasses generally have more sensitive nerves in their eyes compared to people with normal vision, so they feel the weight of the load on the area between the eyebrows is stronger, and they often wear lenses that are attached to the front frame of their existing glasses. It is common to have strong dissatisfaction with the method of clipping the photochromic lens onto the frame. Although it is theoretically not impossible to add a dimming function to prescription lenses for correcting refractive errors, it is difficult to make the lenses of regularly worn glasses both prescription and dimming. T P O (t4.me
, pLaae, oaaasion). Conversely, it is also possible to use prescription lenses for goggles (sunglasses) for driving, skiing, or fishing.i.The frames of sunglasses and goggles come in a wide variety of shapes. The lenses generally have a large aperture and are curved to fit the face to ensure visual field, and are fundamentally different in shape from prescription lenses. The prescription corrective lenses required to correct visual acuity and these complex visual acuities are 56
It is said that there are more than 0 types of lenses, and photochromic lenses suitable for various uses are prepared and stocked (this is clear from the circumstances such as the pressure on creditors due to the inventory burden). As such, it can be said that commercialization is practically impossible.

However, the demand for simultaneous fulfillment of dimming function and vision correction function is due to the recent spread of electronic devices such as computers and word processors.
With the emergence of a new occupational disease called Cu1deo display termtnaL) syndrome, myopia, hyperopia,
This is becoming increasingly necessary for operators with visual impairments such as astigmatism or presbyopia.

In response to these circumstances, regular eyeglass users have begun to develop safety glasses that can be worn over existing glasses when it is necessary to prevent glare or protect the eyes from harmful rays.
goggles) are now in demand.

However, even if you classify existing glasses only by the shape and design of the front frame, there are various types such as ``Parisian'', ``Auto'', ``Unilinton'', and ``Boston'', and there are also metal frames in terms of material. Because there are a variety of types of glasses and plastic frames, if you try to stack existing sunglasses or goggles over them, the front frame of the existing glasses below the front frame of the 10 layers of safety glasses will become unsightly. The lenses of the upper safety glasses may come into contact with the lenses of the existing glasses, causing damage to the lenses. ■0 The safety glasses that are worn overlapping each other are placed away from the eyes. As a result, the central part of the front frame (inside the lens rim) obstructs the field of view, making the visual angle narrower. Since the lenses of safety glasses are often curved into a cylindrical shape that follows the shape of a person's face, the left and right shoulders (base end of the temple) of existing glasses
Problems were unavoidable, such as being unable to put on the protective goggles because they interfered with the lens of the protective goggles, and the presence of existing glasses causing the overlapping protective goggles to be placed in the wrong position, causing a sense of discomfort.

The present invention was developed in view of the conventional situation in which there were no protective glasses suitable for protecting the eyes of people who cannot avoid wearing glasses due to refractive error from glare and harmful rays. It is a technical problem to provide practical overlay glasses that can be worn stably and comfortably over wearing glasses.

Another technical object of the present invention is to provide overlapping eyeglasses that can cover the shape of the front frame of most commercially available eyeglasses without exposing them to the outside and that can be layered smartly. be.

Another technical object of the present invention is to provide overlay eyeglasses that can maintain the photochromic lenses in an ideal positional relationship with the lenses of existing eyeglasses so that they can be worn continuously.

Furthermore, another technical object of the present invention is to provide comfortable overlay glasses that can properly maintain the position of already worn glasses and that do not cause overvoltage to be felt in the nose pad. It is in.

Other technical problems and advantages of the present invention will become clearer from the following description.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above technical problem will be described below with reference to the accompanying drawings.

That is, the present invention provides an outer front frame 1 formed to have a width and length sufficient to cover the front edge Gf of the already worn glasses G from the outside.
The upper edge of the front frame L of the front frame L protrudes toward the eyepiece direction, and when placed over the existing glasses G, it can be stably mounted on the upper edge of the front edge Gf in a non-slip state. A frame plate 2 is provided with a non-slip body 21 made of a soft synthetic resin material having a large coefficient of friction on its edge.
and an outer temple 3 pivoted to both left and right ends of the outer front frame 1 so as to be foldable toward the eyepiece side of the outer front frame and with an interval wider than the interval between the temples Gt - Gt of the already worn glasses G. The gist lies in the fact that the above-mentioned technical problem was solved by linking and integrating means such as 3 to create overlay glasses.
