Modes for Carrying Out the Invention

[0009] Hereinafter, the present invention will be described through embodiments of the invention, but the invention according to the utility model registration claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are essential as means for solving the problems. In each figure, those denoted by the same reference numerals have the same or similar configurations.

[0010] FIG. 1 is an overall perspective view of the eyewear 100 according to the present embodiment. The eyewear 100, which is an aspect of glasses for correcting eyesight, includes lenses 110, inner rims 120, outer rims 130, a bridge 140, a frame 150, temple pieces 160, and temple ends 170.

[0011] In the present embodiment, it is assumed that the lenses 110 are lenses for high myopia with a strength stronger than -6.0D. Such lenses for high myopia have a convex surface on the outer side and a concave surface on the eyeball side, and have a shape in which the thickness increases from the center part to the end part of the lens.

[0012] The inner rims 120 surround the outer peripheral portion of the lenses 110 and hold the lenses 110. The outer rims 130 surround the outer peripheral portion of the inner rims 120 and hold the inner rims 120 that hold the lenses 110. The inner rims 120 and the outer rims 130 may be made of resin materials such as acetate, TR90 (grilamid), super empla, and celluloid, but in the present embodiment, it is assumed that metal materials such as titanium, stainless steel, and white metal (nickel alloy) are adopted.

[0013] The bridge 140 connects the outer rim 130 for the right eye and the outer rim 130 for the left eye. Each of the outer rim 130 for the right eye and the outer rim 130 for the left eye has the frame 150 connected to the outer side opposite to the inner side connected to the bridge 140, and the temple pieces 160 and the temple ends 170 extend in order continuously to the frame 150.

[0014] The temple end 170 is an ear hook portion that hangs on the wearer's ear and is provided continuously with the temple 160. The temple end 170 may be integrally formed with the temple 160 or may have a modern separate configuration. The armor 150 and the temple 160 may be made of a resin material, but in this embodiment, it is assumed that a metal material such as titanium or stainless steel is adopted. When the temple end 170 is integrally formed with the temple 160, it may be made of a metal material, but when it is configured separately, it is preferably made of a resin material.

[0015] The temple end 170 has an inner surface 171 that is inclined so that the upper part is located outside the lower part, and is configured to hold the wearer's head on the tip side. Since the temple end 170 is configured by a three-dimensional curve in this way, even if the heavy lens 110 for high myopia is located forward, it is possible to prevent the eyewear 100 from slipping forward and improve the wearing comfort of the wearer.

[0016] In this embodiment, as shown by the coordinate axes in the figure, the extension direction of the temple 160 is defined as the X-axis direction, the arrangement direction of the two lenses 110 is defined as the Y-axis direction, and the direction orthogonal to the X-axis direction and the Y-axis direction is defined as the Z-axis direction. In the subsequent drawings, the same coordinate axes are also noted based on the state where the eyewear 100 is arranged as shown in FIG. 1, so as to indicate the orientation of the structure represented by each drawing. In particular, the positive X-axis direction may be referred to as "rear", the negative X-axis direction as "front", the positive Z-axis direction as "up", and the negative Z-axis direction as "down". Also, the side where the wearer's head is located between the two opened temples 160 in the Y-axis direction may be referred to as "inner", and the opposite side as "outer".

[0017] FIG. 2 is an exploded perspective view of the periphery of the lens of the eyewear 100. The inner rim 120 is formed in an annular shape, and specifically, as will be described later, a dividing line 121 that divides the ring is provided at one location. The lens 110 is incorporated and held in the inner peripheral portion of the inner rim 120 where the ring is temporarily expanded by the dividing line 121.

[0018] The outer rim 130 is also formed in an annular shape similar to the inner rim 120. When the screw 151 provided on the armor 150 is loosened, the ring is temporarily expanded. The inner rim 120 that holds the lens 110 is incorporated into the inner peripheral portion of the outer rim 130 in that state and is fixed to the outer rim 130 when the screw 151 is tightened.

[0019] Figure 3 is a cross-sectional view taken along plane A in Figure 1. Specifically, it is a view observed by looking down at the cross-section of plane A from above.

[0020] As shown in the figure, the thickness (Tiy, Tib) of the inner rim 120 along the thickness direction (X-axis direction) of the lens 110 is greater than or equal to the thickness (Toy, Tob) of the outer rim 130 (Tiy > Toy, Tib > Tob). That is, the inner rim 120 covers a wider range of the side surface of the lens 110, making it difficult for a third party to directly see the thickness of the lens 110 when observing the wearer from the side. Also, by making the thickness of the outer rim 130 smaller than the thickness of the inner rim 120, a height difference is created between the inner rim 120 and the outer rim 130 along the outer peripheral portion, making the thickness of the lens 110 less noticeable and enhancing the design.

[0021] Also, for the inner rim 120, the thickness (Tiy) on the armor side is greater than the thickness (Tib) on the bridge side (Tiy > Tib). By having such a relationship, when a third party observes the wearer from the side, the thickness of the lens 110 is made less directly visible, and the sense of discomfort in the wearer's field of vision on the bridge side can be reduced.

[0022] Further, the protruding amounts (Tdy1, Tdb1) of the lens 110 toward the concave side with respect to the outer rim 130 of the inner rim 120 are larger than the protruding amounts (Tdy2, Tdb2) toward the convex side of the lens 110 (Tdy1 > Tdy2, Tdb1 > Tdb2). By having such a relationship, when a third party observes the wearer from the front as described later, the inner rim 120 and the outer rim 130 can be observed separately, and when a third party observes the wearer from the side, the thickness of the lens 110 is made less conspicuous.

[0023] FIG. 4 is a front view of the eyewear 100 and a partial enlarged view. When viewed from the front, the inner rim 120 surrounding the lens 110 and the outer rim 130 further surrounding the outer periphery thereof can be observed as a double annulus.

[0024] In the present embodiment, the lens 110 is colored so that the light reflectance of the color of the inner rim 120 is higher than the light reflectance of the color of the outer rim 130. That is, the inner rim 120 located on the inner peripheral side is made brighter, and the outer rim 130 located on the outer peripheral side is made darker. By providing such a difference, the eyes of the wearer, which tend to look smaller due to the high-power lens 110, are prevented from looking smaller by the optical illusion effect. Such a difference in brightness may be realized by coloring the inner rim 120 and the outer rim 130, or may be realized by a difference in the materials of the inner rim 120 and the outer rim 130.

[0025] Further, as shown in the enlarged view, the width (Wo) of the outer rim 130 along the plane direction of the lens 110 is preferably set to be equal to or greater than the width (Wi) of the inner rim 120 (Wo ≧ Wi). By setting such a width, the optical illusion effect of preventing the eyes of the wearer from looking smaller can be enhanced more.

[0026] FIG. 5 is a perspective view of the inner rim 120. As described above, the inner rim 120 is provided with a dividing line 121 that divides the ring. The dividing line 121 is formed in a non-linear shape along the thickness direction (X-axis direction) of the lens 110. More specifically, in this embodiment, it is formed in a bent line shape. By forming the dividing line 121 in this way, it is possible to prevent the lens 110 from easily detaching from the inner rim 120 in the operation of fixing the lens 110 incorporated in the outer rim 130. The dividing line 121 may have a shape that can be divided so that one engages with the other, such as a wavy line in addition to the bent line.
