2 . The eyewear of claim 1 , wherein the lens comprises one surface facing the user, the other surface facing the outside, lateral edges in a left-right direction, and upper and lower edges in a top-bottom direction, and wherein the frame is coupled to only one surface at each of the lateral edges of the lens.
3 . The eyewear of claim 1 , wherein in the first frame or the second frame, a first width at a position close to the center of the lens on a cross-section of a horizontal plane identical to a horizontal plane of the lens, is smaller than a second width at a lateral edge of the lens.
4 . The eyewear of claim 1 , further comprising a coloration layer disposed between the lens and the adhesive layer and applied to the surface-treated area of the lens.
5 . The eyewear of claim 1 , wherein the surface-treated area of the lens is formed by creating scratches in a portion of a surface of the lens by laser cutting or etching, and wherein the surface-treated area is composed of: a first scratch sloping and spaced apart in a first direction toward the center of the lens, which is a direction in which the recessed guide groove of the lens is formed; a second scratch sloping and spaced apart in a direction different from the first direction; and a third scratch spaced apart in a direction perpendicular to the first direction toward the center of the lens.
6 . The eyewear of claim 1 , wherein the frame bonding surface further comprises an overflow prevention line protruding to form a closed curve on an outer edge.
7 . The eyewear of claim 6 , wherein the frame bonding surface further comprises a recessed line formed by being recessed inside a closed curve formed by the overflow prevention line adjacent to a position where the overflow prevention line is formed, thereby forming a closed curve.
8 . The eyewear of claim 7 , wherein an inner area of the recessed line of the frame bonding surface curves toward the center so that a surface in contact with the lens faces the lens.
9 . The eyewear of claim 1 , wherein the recessed guide groove of the lens has a vertical cross-section that is convexly curved toward the center of the lens, wherein a vertical cross-section the protruding guide portion at each of the both side ends of the frame has a concave shape that gradually curves inward toward the center to correspond to a shape of the recessed guide groove, and wherein when the protruding guide portion of the frame is coupled to the recessed guide groove of the lens, the protruding guide portion is slidably coupled so that a concave shape of the protruding guide portion corresponds to a curved shape of the recessed guide groove.
10 . The eyewear of claim 1 , wherein the recessed guide groove of the lens is formed as a plurality of recessed guide grooves, spaced apart from each other, and the protruding guide portion of the frame is also formed as a plurality of protruding guide portions, spaced apart from each other, to correspond to a number of the recessed guide grooves.

Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Patent Application No. PCT/KR2023/003231, filed Mar. 9, 2023, which claims priority to KR10-2022-0059988, filed May 17, 2022, the entire contents of each of which are incorporated herein by reference in their entirety. TECHNICAL FIELD The present disclosure relates to eyewear with minimized exposure of a frame to the outside. BACKGROUND ART Eyewear includes general eyeglasses made of a transparent material with adjustable refractive indices, and products such as sunglasses and goggles that reduce light transmission to prevent glare and protect a user's eyes from ultraviolet rays. Sunglasses and similar products commonly use transparent materials with added dyes or coatings, or materials that reflect light, to manufacture them. This is done to reduce glare for users and protect their eyes from ultraviolet rays. Commonly used sunglasses and the like are manufactured by adding colorants to transparent eyeglass materials or coating or depositing light-reflecting materials to reduce glare to users or protect their eyes from ultraviolet rays. Meanwhile, in general, eyewear consists of a lens, which is clear or colored in a transparent part, a frame to support the lens, and temples connected to the frame and securing the eyewear to a user's face. Recently, due to various individual styles, design has become a crucial factor in eyewear, beyond its inherent functionality. As a result, eyewear with various designs to cater to different preferences are manufactured. Meanwhile, the frame is fixed to the edge of the lens, serving the dual purpose of protecting the lens and connecting it to the temples. A frame with minimized visibility from the outside is often highly praised for its superior design. In other words, it is possible to minimize the portion of the frame visible from the outside when viewed from a user's facial profile. In this case, from the user's facial profile, only the lens is practically visible, thus providing eyewear that is exceptionally superior in design. However, the basic function of the frame is to support the lens and connect the lens to the temples, but if the frame is minimized, this function may be compromised. Therefore, there is a need for eyewear that minimizes the frame's visibility from the outside while stably supporting the lens, securely connecting the lens and the temples, and providing durability. DISCLOSURE Technical Problem Accordingly, an object of the present disclosure is to provide eyewear capable of minimizing a portion of a frame visible from the outside of a lens. In particular, the object is to provide eyewear capable of minimizing visibility of a frame from the outside of a lens in which a left-eye portion and a right-eye portion are integrated. In addition, another object of the present disclosure is to provide eyewear capable of securely connecting and fixing a lens and temples while minimizing a frame, preventing the frame from easily detaching from the lens, and enhancing durability by preventing an adhesive material from escaping to the outside. In addition, yet another object of the present disclosure is to provide eyewear capable of minimizing a frame while coupling the frame to an accurate position of the lens. Technical objects of the present disclosure are not limited to the above-described objects and other technical objects that have not been described above may become evident to those skilled in the art from the following description. Technical Solution In one aspect, there is provided eyewear with minimized exposure of a frame to the outside, the eyewear including: a lens formed at a position facing a user's left and right eyes when the eyewear is worn, with integrated portions corresponding to the left and right eyes; a frame comprising a first frame and a second frame, each coupled to one surface at each of both side ends of the lens; and a temple coupled to the frame. The frame is coupled to one surface of the lens with an adhesive layer interposed. The lens includes a recessed guide groove formed by being recessed inward from each of the both side ends toward center of the lens, and the frame comprises a protruding guide portion to be inserted into the recessed guide groove of the lens when being coupled at each of the both side ends of the lens. The protruding guide portion of the frame is exposed to an outside through the recessed guide groove on the other surface of the lens, so that the frame contacts only one surface at each of the both side ends of the lens. Further, the lens may include one surface facing the user, the other surface facing the outside, lateral edges in a left-right direction, and upper and lower edges in a top-bottom direction, and the frame may be coupled to only one surface at each of the lateral edges of the lens. In addition, in the first frame or the second frame, a first width at a position close to the center of the lens on a cros
