Description

  The present invention relates to a dustproof device for spectacles which is detachably attached to spectacles, and in particular, a dustproof function such as protecting eyes from pollen while wearing spectacles (prescription glasses) which are always used. The present invention relates to a dustproof device for spectacles that can be effectively and inexpensively performed.

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

  As shown in FIG. 5, for example, a conventionally proposed and practically used dust-proof eyeglass 2 has a curved ear hook for engaging with the ear so that the dust-proof eyeglass 2 can be worn as eyeglasses by itself and fixed to the face. This is a configuration including a temple 21 having Here, for those who use spectacles (particularly a problem with prescription spectacles), in order to wear the dust-proof spectacles 2 to protect the eyes from pollen and the like, the prescription spectacles used It is necessary to further attach the dust-proof glasses 2 from above, or to remove the prescription glasses being used before attaching the dust-proof glasses 2.

  However, when the dust-proof glasses 2 are further worn over the prescription glasses, the temple of the prescription glasses and the temple 21 of the dust-proof glasses 2 overlap with each other. There is a problem that the dust-proof function is impaired because the dust-proof function is likely to come off or to be displaced without being closely attached. In addition, since the prescription glasses and the dust-proof glasses 2 are separate bodies and are not interlocked with each other, it is difficult to adjust the mounting position of each other, so that a wide gap is easily generated between the dust-proof glasses 2 and the face. As a result, there is a problem that the dustproof function is impaired. If the front frame 22 of the dust-proof glasses 2 is excessively pressed against the face in order to suppress such deterioration of the dust-proof function as much as possible, the prescription glasses are also excessively pressed against the face, resulting in an increased feeling of oppression. There is also a problem of giving discomfort to the person.

  On the other hand, when the dustproof glasses 2 are attached after removing the prescription glasses used, although the above problem does not occur, it is not practical because it naturally causes a problem of a decrease in visual acuity. A configuration in which the dust-proof glasses 2 themselves are prescription glasses can be considered, but there is a problem that the cost is increased.

  Therefore, it is desired to propose a spectacle dust protector which can be detachably attached to spectacles (prescription spectacles) which are always used.

  Here, so-called hanging glasses have been conventionally proposed as having a configuration that can be detachably attached to the glasses (for example, see Patent Document 3).

However, such a pair of eyeglasses is proposed for the purpose of obtaining a state of wearing sunglasses, or for the purpose of correcting vision of prescription glasses, and can be detachably attached to the eyeglasses. However, it does not exert any dustproof function on the glasses.
