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 peripheral edge of the inner lens 52. The flange 52a rises diagonally forward toward the inside 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 base of the flange 52a). The user removes the outer lens 54 from the inner lens 52 in a bent state, attaches an object to be held to the front surface of the inner lens 52, and fits the outer lens 54 into the inside of the flange 52a in the bent state to fit the inner lens 52. Attach to.

As a result, the object to be held is sandwiched between the front surface of the inner lens 52 and the rear surface of the outer lens 54, so that the position of the object to be held is less likely to shift even if the eyelids or the eyeballs move. Further, since the outer lens 54 is fitted in the flange 52a, the outer lens 54 is hard to come off. Further, since the inner lens 52 and the outer lens 54 are made of a hard contact lens, the outer lens 54 can be easily fitted into the inner lens 52. Further, since the opening into which the object to be inserted can be inserted is formed in the front surface of the inner lens 52, the object to be inserted can be inserted from the front surface of the inner lens 52, and the object to be inserted can be easily inserted.

Further, in the first to tenth embodiments and modifications thereof, the inner lens 12 and the outer lens 14 have a close contact structure in which they are in close contact with each other without holding an object to be held, but the present invention is not limited to this. A space may be provided between the two, and the object to be sandwiched may be accommodated in the space, and the object to be sandwiched may be sandwiched between the inner lens 12 and the outer lens 14. Specifically, for example, as in the holes 12a and 14a in the second to fourth embodiments, a space for accommodating the object to be held is formed on the front surface of the inner lens 12 or the rear surface of the outer lens 14. Is possible. This space can be formed in any number, any size, any shape, any place, and may be partially open. For example, a modified example of FIGS. 24 to 31 can be adopted.
