Description

  The present invention relates to an eyelash clip, and more particularly to an eyelash clip for a load test suitable for testing for drooping eyelids.

  Senile blepharoptosis is a problem. The opening of the upper eyelid involves the oculomotor-dominated levator levator muscle, the associated levator aponeurosis, and the sympathetic innervated Muller muscle. As age-related changes, when the levator aponeurosis stretches or the levator aponeurosis deviates from the heel plate, it causes drooping eyelids. I will have to. As a result, the sympathetic nerves can become overstrained, causing headaches, stiff shoulders, coldness, insomnia, depression, and fatigue. For example, see Non-Patent Document 1 and Non-Patent Document 2.

  As shown in FIG. 1A to FIG. 1C, the eyelid function test for attaching the clip 9 to the eyelashes 8 of the upper eyelid and inspecting the opening force is performed as the eyelash clip load test. Proposed. See Non-Patent Document 3.

  As shown in FIGS. 1A to 1C, by hanging the clip 9 on the eyelashes 8 and applying a load to the Muller muscle or the like, even eyelid drooping inconspicuous can be revealed. For example, if a normal person attaches 2 to 4 g of the clip 9 to the eyelashes 8 of the upper eyelid, as shown in FIG. A person with strong opening force can also open a 12.5g clip. However, in the case of a person with a weak opening force, as shown in FIG. Therefore, even if a person who looks normal at first glance can detect whether or not the clip 8 can be sufficiently opened by attaching the clip 8 to the eyelashes 9 of the upper eyelid, it is clear even in inconspicuous eyelid drooping can do.

  As shown in FIG. 1C, on the one hand, in order to know the eye opening force of the eye wearing the clip 9, the right eye eyebrows width 10 in FIG. 1C is measured, and on the other hand, the clip 9 is attached. Measure the width 10 of the eye on the opposite (left) eye and compare both measurements.

  The conventional clip 9 used by the present inventor during such an eyelash clip load test is generally used as a stationery. For example, the clip 9 shown in FIGS. 1A to 1C and FIGS. 2A to 2C is a transparent clip “Purabatatsume” (J8582) manufactured by Kyoei Plastic Co., Ltd. The clip 9 is originally a stationery of 3.2 g, but the present inventor has diverted it to the eyelash clip load test.

  The clip 9 has a pair of clamping parts 1 and 2. Since these clamping parts 1 and 2 are wide and are not provided with a window, it is difficult to measure the crack width 10.

In a state where the conventional clip 9 is attached to the eyelashes 8 of the upper eyelid, as shown in FIG. 1A, most of the eye part is hidden by the holding part 2, or as shown in FIG. Part 1 touches the lower eyelid. Further, when the eyelid is opened, the lower eyelid may be dragged upward. In either case, it is not easy to measure the burst width 10 accurately.
