Description

  The present invention relates to a spectacle dustproof tool that is detachably attached to spectacles, and in particular, a dustproof function such as protecting eyes from pollen while wearing spectacles that are always used (spectacles with degrees). It is related with the dustproof tool for spectacles which can show | play effectively and cheaply.

  Conventionally, various dustproof glasses have been proposed to protect eyes from dust, flying, wind pressure, etc. in addition to pollen (see, for example, Patent Documents 1 and 2).

  As shown in FIG. 6, for example, the conventionally proposed and practical dustproof glasses 2 are worn as glasses themselves, and curved ear-hanging portions to be engaged with the ears so that they can be fixed to the face portions. It is the structure provided with the temple 21 which has. Here, for those who use spectacles (especially in the case of prescription spectacles), in order to wear the dustproof spectacles 2 to protect the eyes from pollen etc., the prescription spectacles used Further, it is necessary to attach the dustproof glasses 2 from above, or to attach the dustproof glasses 2 after removing the used glasses.

  However, when the dust-proof glasses 2 are further mounted on the prescription glasses, the temples of the prescription glasses and the temples 21 of the dust-proof glasses 2 overlap, so that not only a sense of incongruity is generated, but also the temple 21 of the dust-proof glasses 2 There is a problem that the dustproof function is impaired because it is difficult to adhere to the ear and easily comes off or is displaced. Further, the prescription glasses and the dustproof glasses 2 are separate bodies and are not linked to each other, so that it is difficult to adjust the mounting position of each other, and thus a wide gap is easily generated between the dustproof glasses 2 and the face. As a result, there is also a problem that the dustproof function is impaired. In order to suppress such a decrease in the dustproof function as much as possible, if the front frame 22 of the dustproof glasses 2 is excessively pressed against the face side, the prescription glasses are also excessively pressed against the face side, resulting in increased pressure and use. There is also the problem of giving discomfort to the person.

  On the other hand, when the dust-proof glasses 2 are worn after removing the glasses with the degree of use, the above problem does not occur, but it naturally causes a problem of a reduction in visual acuity, which is not practical. Although a configuration in which the dustproof glasses 2 themselves are prescription glasses is also conceivable, there is a problem that costs are increased.

  Therefore, it is desired to propose a spectacle dustproof tool that can be detachably attached to spectacles that are always used (glasses with prescription).

  Here, as what has a structure which can be attached or detached detachably with respect to spectacles, what is called front spectacles is proposed conventionally (for example, refer to patent documents 3).

However, such front spectacles have been proposed for the purpose of obtaining a state in which sunglasses are worn, or for the purpose of correcting the visual acuity of prescription spectacles, and can be detachably attached to the spectacles. However, it does not provide any dustproof function for the glasses.
