Like the inner lens 12 and the outer lens 14, the electronic device 20 has a spherical shell shape as a whole. Specifically, the rear surface of the electronic device 20 has a spherical shape with a curvature that is the same as or close to the front surface of the inner lens 12 so as to fit the front surface of the inner lens 12. Similarly, the front surface of the electronic device 20 has a spherical shape with a curvature that is the same as or close to the rear surface of the outer lens 14 so as to fit the rear surface of the outer lens 14. As the electronic device 20, a known eye device such as a camera, a projector or a sensor can be adopted.

Next, the operation of this embodiment will be described.
FIG. 3 is a diagram for explaining a method of mounting the electronic device 20.

23A and 23B are diagrams showing the contact lens 50, where FIG. 23A is a front view of the contact lens 50, and FIGS. 23B and 23C are sectional views taken along the line AA of FIG.

As shown in FIG. 23, the contact lens 50 is configured to have an inner lens 52 made of a hard contact lens and an outer lens 54 made of a hard contact lens arranged facing the front surface of the inner lens 52. There is. The inner lens 52 and the outer lens 54 have a basic shape conventionally known as a hard contact lens, and have a spherical shell shape as a whole.

A flange 52a is formed on the front edge of the inner lens 52. The flange 52a rises diagonally forward toward the inner side of the inner lens 52. The diameter of the outer lens 54 is substantially the same as the inner diameter of the inner lens 52 (the diameter of the inner root of the flange 52a). The user removes the outer lens 54 from the inner lens 52 in a bent state, attaches a sandwiched object to the front surface of the inner lens 52, and fits the inner lens 52 in a bent state of the outer lens 54 to fit the inner lens 52. Attach to.

As a result, the object to be clamped is clamped between the front surface of the inner lens 52 and the rear surface of the outer lens 54, and thus the position thereof is unlikely to shift even if the eyelid or eyeball moves. Further, since the outer lens 54 is fitted in the flange 52a, it is difficult for the outer lens 54 to come off. Further, since the inner lens 52 and the outer lens 54 are hard contact lenses, it is easy to fit the outer lens 54 into the inner lens 52. Further, since the opening through which the object to be sandwiched can be inserted is formed in the front surface of the inner lens 52, the object to be sandwiched can be inserted from the front surface of the inner lens 52, and the object to be sandwiched can be easily inserted.

Further, in the first to tenth embodiments and the modified examples thereof, the inner lens 12 and the outer lens 14 have a close contact structure in which both are in close contact with each other without holding the object to be held, but the present invention is not limited to this. It is also possible to provide a space between the two, and a space structure in which the object to be sandwiched is housed in the space and the object to be sandwiched is sandwiched by the inner lens 12 and the outer lens 14. Specifically, for example, like the holes 12a and 14a in the second to fourth embodiments, a space for accommodating an object to be sandwiched is formed on the front surface of the inner lens 12 or the rear surface of the outer lens 14. It is possible. This space can be formed in an arbitrary number, an arbitrary size, and an arbitrary shape at an arbitrary position, and a part thereof may be opened. For example, the modified examples of FIGS. 24 to 31 can be adopted.

24A and 24B are views showing the contact lens 50. FIG. 24A is a front view of the contact lens 50, and FIGS. 24B and 24C are sectional views taken along the line AA of FIG.

The modification of FIG. 24 differs from the modification of FIG. 23 in that the flange 52a of the inner lens 52 is further raised and the diameter of the outer lens 54 is slightly larger than the tip diameter of the flange 52a. is there. Therefore, when the outer lens 54 is fitted into the flange 52a, the outer lens 54 can be fixed near the tip of the flange 52a, so that a space 58 is formed between the inner lens 52 and the outer lens 54. The user removes the outer lens 54 from the inner lens 52 in a bent state, accommodates a thick object to be sandwiched in the space 58, and fits the outer lens 54 in a bent state inside the flange 52a. Attach to lens 52.

As a result, a thick object to be sandwiched can be clamped.
FIG. 25 is a view showing the contact lens 50, (a) is a front view of the contact lens 50, and (b) and (c) are sectional views taken along the line AA of (a).

The modified example of FIG. 25 is different from the modified example of FIG. 24 in that a through hole 54a is formed through the outer lens 54 in the front-rear direction. The through hole 54a is formed in the center of the outer lens 54. The roles of the through holes 54a are to reduce optical interference, allow components of the drug 30 to pass through, enhance oxygen permeability, and the like. As for the necessity of reducing the optical interference, it is assumed that the lens is sandwiched as an object to be sandwiched, or that the user wears it without adjusting the visual acuity.

As a result, when the medicine 30 is contained in the space 58, the medicine 30 sandwiched between the inner lens 52 and the outer lens 54 is melted out, passes through the through hole 54a, and the component thereof is placed on a part such as an eyelid or an eyeball. Is supplied, the drug 30 can be effectively supplied. Further, since the medicine 30 can be stored in the space 58, the liquid medicine 30 can also be used.

The modified example of FIG. 26 is different from the modified example of FIG. 25 in that a plurality of (four in the example of the same figure) through holes 54 b that penetrate the outer lens 54 in the front-rear direction are formed. The through hole 54b has a smaller diameter than the through hole 54a, and is formed above, to the right, below, and to the left of the through hole 54a.

Thereby, when the medicine 30 is contained in the space 58, the medicine 30 sandwiched between the inner lens 52 and the outer lens 54 is melted out, passes through the through holes 54a and the respective through holes 54b, and the eyelid, the eyeball, and the like. Since the component is supplied to the site of, the amount of the drug 30 can be adjusted.

27A and 27B are diagrams showing the contact lens 50. FIG. 27A is a front view of the contact lens 50, and FIG. 27B is a sectional view taken along the line AA of FIG.

The modification of FIG. 27 differs from the modification of FIG. 23 in that the inner lens 52 and the outer lens 54 are integrally molded. The outer lens 54 has a circular arc shape which is defined by an approximately 1/3 circular arc and an arc (an arc, an elliptic arc, etc.) connecting both ends of the inner lens 52 below the inner lens 52. The arc of the outer lens 54 is joined to the inner lens 52, and the outer lens 54 has a pocket shape as a whole. A space 58 is formed between the inner lens 52 and the outer lens 54. In addition, the portions other than the joint 56 between the inner lens 52 and the outer lens 54 are open, and the object to be sandwiched can be inserted through this opening. The user stores a thick object to be sandwiched in the space 58.

As a result, the object to be clamped is clamped between the front surface of the inner lens 52 and the rear surface of the outer lens 54, and thus the position thereof is unlikely to shift even if the eyelid or eyeball moves. Further, when the medicine 30 is contained in the space 58, the medicine 30 sandwiched between the inner lens 52 and the outer lens 54 is melted out from the opening of the pocket, and the component is supplied to a site such as an eyelid or an eyeball. Therefore, the medicine 30 can be effectively supplied. Furthermore, since the drug 30 can be stored in the space 58, the liquid drug 30 can be used.

28A and 28B are views showing the contact lens 50. FIG. 28A is a front view of the contact lens 50, FIG. 28B is a perspective view of the contact lens 50, and FIG. 28C is a view taken along the line AA of FIG. FIG.

The modified example of FIG. 28 is different from the modified example of FIG. 27 in that the outer lens 54 is configured separately from the inner lens 52, and the rear peripheral edge 56 of the outer lens 54 contacts the inner lens 52 over the entire circumference. That is the point. A plurality of (four in the example of the drawing) projections 54c are formed on the rear surface peripheral edge 56 of the outer lens 54. On the front surface of the inner lens 52, a plurality (four in the example of the drawing) of holes (recesses) 52b for receiving the protrusions 54c are formed. A space 58 is formed between the inner lens 52 and the outer lens 54. The user removes the outer lens 54 from the inner lens 52, accommodates a thick object to be sandwiched in the space 58, and fits the protrusion 54c of the outer lens 54 into the hole 52b of the inner lens 52 to remove the outer lens 54. It is attached to the inner lens 52.

As a result, the object to be clamped is clamped between the front surface of the inner lens 52 and the rear surface of the outer lens 54, and thus the position thereof is unlikely to shift even if the eyelid or eyeball moves. Further, since the outer lens 54 is fixed to the inner lens 52 by receiving the protrusion 54c at the hole 52b, the outer lens 54 is unlikely to come off.

29A and 29B are views showing the contact lens 50. FIG. 29A is a front view of the contact lens 50, FIG. 29B is a perspective view of the contact lens 50, and FIG. 29C is a view taken along the line AA of FIG. FIG.

The modified example of FIG. 29 is different from the modified example of FIG. 28 in that a through hole 54 d that penetrates the outer lens 54 in the front-rear direction is formed. The through hole 54d is formed in the center of the outer lens 54.

As a result, when the medicine 30 is contained in the space 58, the medicine 30 sandwiched between the inner lens 52 and the outer lens 54 is melted out, passes through the through hole 54d, and its components are placed on the eyelid, eyeball or the like.

It is attached to the inner lens 52.

As a result, the object to be clamped is clamped between the front surface of the inner lens 52 and the rear surface of the outer lens 54, and thus the position thereof is unlikely to shift even if the eyelid or eyeball moves. Further, since the outer lens 54 is fixed to the inner lens 52 by receiving the protrusion 54e in the hole 52c, the outer lens 54 is unlikely to come off.

FIG. 31 is a view showing the contact lens 50, (a) is a front view of the contact lens 50, and (b) and (c) are sectional views taken along the line AA of (a).

The modification of FIG. 31 is different from the modification of FIG. 30 in that a through hole 54f is formed in the outer lens 54 so as to penetrate the lower surface in the vertical direction.
