Description

  The present invention relates to eyeglasses for dry eyes, and more particularly to eyeglasses for dry eyes provided with a humidifying body.

  Conventionally, as eyeglasses for dry eyes, one in which a humidifying body holding moisture is attached to a spectacle frame (a temple, a rim, or a wisdom portion) is already known (see, for example, Patent Documents 1 and 2). .

However, such conventional eyeglasses for dry eye are easy to evaporate the moisture of the humidifying body, quickly dry and become a dry state, so it is necessary to replenish moisture frequently or replace the humidifying body itself, There was a problem.
Therefore, it may be possible to make it difficult to evaporate by, for example, adding viscosity to moisture, but if it is difficult to evaporate, moisture will be insufficient this time and it will not be used as dry eye glasses in the first place. It was real.

  The present invention has been made in view of the above-described conventional problems and situations, and an object of the present invention is to provide dry eyeglasses that can control the suppression and promotion of moisture transpiration in a well-balanced manner.

  As a result of various studies to solve the above problems, the present inventor, even when using moisture that is difficult to evaporate at room temperature, if the body temperature of the temporal head that is in contact with the glasses is used, the moisture Since the transpiration of the water is promoted, it has been found that the suppression and promotion of moisture transpiration can be controlled in a balanced manner, and the present invention has been completed.

  That is, the present invention includes a moisture vaporizer that evaporates moisture inside a temple of the spectacle frame, a heat receiver that receives heat from the temporal region in contact with the temporal region when the spectacles are mounted, and heat of the heat receiver. The above-mentioned problems are solved by eyeglasses for dry eyes, characterized by comprising a heat conductor that transmits heat to a moisture vaporizer.

When the dry eyeglasses of the present invention are used, the body temperature of the temporal region is sequentially transmitted to the heat receiving body, the heat conductor, and the moisture vaporizer when wearing the glasses, and moisture that is not easily evaporated at room temperature due to the transmitted heat. As a result of the promotion of transpiration, the suppression and promotion of moisture transpiration can be controlled in a well-balanced manner, so that moisture can be stably supplied for a long time.
In particular, when the eyeglasses for dry eye according to the present invention are not worn, moisture hardly evaporates, and therefore, the frequency of water supply and the replacement frequency of the moisture supply member are considerably reduced as compared with the prior art.

  Embodiments of the present invention will be described below with reference to the drawings.

  In FIGS. 1 and 2, reference numeral 10 denotes a temple of a spectacle frame, to which a moisture vaporizer 20, a heat receiver 30, and a heat conductor 40 are attached.

  The moisture vaporizer 20 may have any specific structure as long as it can vaporize moisture. For example, as shown in FIGS. 3 and 4, the moisture vaporizer 20 has an appropriate number of vaporization holes 21 a in the surface plate portion. A container in which the water retaining member 22 retaining moisture is accommodated in the container body 21 so as to be exchangeable is preferably used. Here, the vessel body 21 is preferably made of metal having excellent thermal conductivity. The water retaining member 22 is not particularly limited as long as it can retain moisture, but, for example, sponge, sponge, felt, paper or the like is used. In addition, as the water retained in the water retaining member 22, it is possible to prevent the material that has suppressed transpiration at room temperature, for example, 30 ° C. or less by adding a substance such as hyaluronic acid to the water, and is prevented from drying in a short time. This is desirable.

When the moisture vaporizer 20 is attached to the eyeglass, the moisture vaporizer 20 is detachably attached to a portion near the eyes, more specifically, inside the vicinity of the hinge portion 50 of the temple 10, so that the moisture is efficiently evaporated around the eyes. In addition, the moisture vaporizer 20 can be easily replaced, which is desirable. The detachable attachment method may be any method such as an elastic fitting method, a locking method using protrusions and grooves, and the like.
In addition, the moisture vaporizer 20 is partly attached (see FIG. 3) or all of the moisture vaporizer 20 is embedded in the temple 10 so that the moisture vaporizer 20 is less likely to enter the field of view. It is desirable because it is refreshing.

The heat receiving body 30 is attached to the inside of the temple 10 in contact with the temporal region when wearing glasses, and receives heat from the temporal region. The heat receiving body 30 may be any material such as a metal or a synthetic resin as long as it is a material having good thermal conductivity, and is particularly made of a metal that has excellent thermal conductivity such as titanium and does not adversely affect the skin. It is desirable to do. In this case, the shape of the heat receiving body 30 is preferably a thin plate having a surface area as large as possible in order to efficiently receive heat from the temporal region.
In addition, the heat receiving body 30 may be attached simply to the inside of the temple 10, but as shown in FIG. 5 (1), a part of the heat receiving body 30 may be embedded in the temple 10. As shown in 5 (2), it is desirable to embed the whole in the temple 10 and attach it without wearing a side head when wearing glasses. In addition, when a part is embedded in the temple 10, it is desirable in terms of safety that the protruding edge portion of the heat receiving body 30 is a curved surface.

The heat conductor 40 transmits the heat of the heat receiving body 30 to the moisture vaporizer 20, and one end thereof is connected to the heat receiver 30 and the other end is connected to the moisture vaporizer 20. The material of the heat conductor 40 is the same as that of the heat receiving body 30 described above. In particular, a metal having excellent heat conductivity such as titanium is used, and an integrally formed body with the heat receiving body 30 is formed as a heat. Desirable in terms of conductivity. In this case, the heat conductor 40 is formed in a tape shape that is narrower than the heat receiving body 30, and the other end connected to the moisture vaporizer 20 is in close contact with the outer bottom surface of the moisture vaporizer 20 as shown in FIG. 4. This is desirable for efficiently transferring the temporal heat to the moisture vaporizer 20.
Further, like the heat receiving body 30, it is desirable that a part or all of the heat conductor 40 (see FIG. 4) is embedded and attached in the temple without giving a sense of protrusion.
