Best Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. In this example, descriptions of technologies that are already known will be omitted. Also, the structures and methods for embodying the technical idea of the invention are exemplified, and the technical idea of the present invention is not limited to the following. The technical idea of the present invention can be variously modified within the scope of the matters described in the claims. In particular, it should be noted that the drawings are schematic and different from the actual ones. In this example, when a person stands upright, the height direction is defined as the vertical direction, the direction of looking at the person from the front perpendicular to this vertical direction is defined as the front direction, and the direction perpendicular to the vertical direction and the front-back direction is defined as the side direction.

[0018] Referring to FIG. 1, there is an extension 1 to be attached to the natural eyelashes 3. The extension 1 is formed from a gradually thinner shape to a thicker shape from the base B on the side to be attached to the natural eyelashes 3, and is formed from a thicker shape to a thinner shape toward the tip T of the extension 1 with a predetermined position as a boundary.

[0019] That is, it gradually becomes thicker from the base B of the extension 1. That is, the thickness D1 is thicker than the thickness D2. And the thickness becomes maximum (thickness D1) at the distance L1 from the base B, and gradually becomes thinner with this distance L1 as a boundary. That is, the thickness D4 is thinner than the thickness D2. And it becomes thinnest at the tip T at a position separated by the remaining distance L2. Here, the distance L1 and the distance L2 may be different lengths or the same length. That is, it is adjusted to match the length and shape of the individual's natural eyelashes 3.

[0020] Referring to FIG. 2, it is the shape of the cross-section II-II in FIG. 1. The cross-sectional shapes of the thin shape and the thick shape are similar shapes. For example, the cross-sectional shape is circular as shown in FIG. 2(a), elliptical as shown in FIG. 2(b), or polygonal as shown in FIG. 2(c). The material of the extension 1 is various, but it is a chemical fiber (such as polybutylene terephthalate).

[0021] As shown in Figure 3, natural eyelashes 3 grow on the eyelid 5. As shown in Figure 4, the eyelash extension 1 is formed from a gradually tapering shape from the base B on the side to be attached to the natural eyelash 3, and then, at a predetermined position, it is formed from a tapering shape towards the tip T of the extension 1. It is desirable to attach the extension 1 from a position where the base B is half the length of the natural eyelash 3. Adhesives such as ethyl cyanoacrylate (ethyl cyanoacrylate), butyl cyanoacrylate (butyl cyanoacrylate), and ethoxyethyl cyanoacrylate (ethoxyethyl) are used for attachment.

[0022] As shown in Figure 4, the eyelash extension 1 is formed by gradually changing from a thin shape to a thick shape from the base B on the side to be attached to the natural eyelash 3, and then changing from a thick shape to a thin shape towards the tip of the extension 1 at a predetermined position. It is preferable to attach the eyelash extension 1 with the base B at a distance S of 2 mm to 4 mm from the eyelid 5 of the natural eyelash 3. For attachment, adhesives such as ethyl cyanoacrylate (ethyl cyanoacrylate), butyl cyanoacrylate (butyl cyanoacrylate), and ethoxyethyl cyanoacrylate (ethoxyethyl) are used.

[0023] As shown in Figure 5, when extensions 1 are attached to the natural eyelashes 3 growing on the upper eyelid 5 of the eye 7, the resulting smooth shape without any steps makes the entire eyelashes appear natural.

[0024] As shown in Figure 6, thicknesses D6 and D7 are almost identical, so no steps or gaps occur near area E. As a result, the entire eyelash looks natural.

[0025] This is an eyelash extension application method that includes an eyelash extension formation step, in which an eyelash extension 1 is formed by gradually changing from a thin shape to a thick shape from the base B on the side to be attached to the natural eyelash 3, and then changing from a thick shape to a thin shape towards the tip T of the extension 1 at a predetermined position; an intermediate position determination step, in which the intermediate position of the natural eyelash 3 is determined; and an eyelash extension attachment step, in which the base B of the extension 1 is aligned with the intermediate position and the extension 1 is attached to the upper side of the natural eyelash 3. There are various methods for manufacturing the eyelash extension 1, but for example, two short false eyelashes with a thick base and a thin tip may be formed and the thick cross-sections of the bases may be bonded together.

[0026] Although embodiments have been described in detail above, the invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope described in the claims. Furthermore, it is possible to combine all or more of the components of the embodiments described above. [Explanation of symbols]
