  Moreover, in the said embodiment and its modification, although the through-hole 12 was formed as a hole which opens a cornea area | region, it is not restricted to this, Arbitrary numbers, arbitrary sizes, arbitrary shapes, arbitrary locations Can be formed. For example, the through-hole 12 can be formed as a hole that opens at least a pupil region (a region located in the pupil 22 at the time of wearing), or can be opened in the surface direction of the medicine supply assisting tool 10. For example, the modification of FIG. 7 is also employable.

FIG. 7 is a front view of the medicine supply assisting tool 10.
Since the amount of movement of the eyeball is greater in the left-right direction than in the up-down direction, from the viewpoint of reducing the possibility or degree of interference with the cornea 24, as shown in FIG. The length of the through hole 12 may be larger than the height (length in the vertical direction) of the through-hole 12. From the same point of view, since the upward and downward movement amount of the eyeball is larger in the upward direction than in the downward direction, the length from the reference point O located at the center of the cornea 24 facing the front when the through-hole 12 is mounted to the upper end. It is possible to adopt a configuration in which the length is longer than the length from the reference point O to the lower end. Considering these two points, the through-hole 12 has, for example, a horizontally long oval shape in which the upper portion expands (a shape in which the width is larger than the height and the length from the reference point O to the upper end is larger than the length to the lower end). A configuration can be employed. In this case, since the relative position of the through-hole 12 with respect to the cornea 24 changes when the medicine supply assisting tool 10 rotates on the surface of the eyeball due to the movement of the eyelids or the eyeballs, there is a possibility that the medicine supply assisting tool 10 rotates. Alternatively, from the viewpoint of reducing the degree, for example, the medicine supply assisting device 10 is such that the upper edge of the medicine supply assisting device 10 is positioned (contact or close) to the upper lid conjunctiva cap and the lower edge is positioned to the lid conjunctiva cap. A configuration for setting the size of 10 can be employed.

  Moreover, in the said embodiment and its modification, although the hole 12 was formed as a through-hole, it is not restricted to this, The recessed part (The case where one part or all part becomes a bottom is included.) It is the same below. Or a recess having an opening on the rear surface (hereinafter collectively referred to as “a recess”).
