Description of the invention: [Technical field to which the invention pertains] [〇〇()1] The present invention relates to a lens for use on land, which is a design that can be designed to improve viewing clarity with a general viewing angle and is ergonomic. Use glasses on the land. [Prior Art] [0002] It is conventional to use a variety of types of glasses on the land, such as sun glasses, sports glasses, goggles, etc., and the lenses of the glasses are rigid, and generally are flat, spherical, cylindrical, and the foregoing The flat lens cannot fit the curvature of the human face, and when used in sports glasses, the drag resistance is lost. Ά' ί.,. /论!替·:3⁄4 As shown in the sixteenth figure, the conventional spherical lens 1' has a circular arc shape, which can reduce the traveling resistance, but the positive circular curvature is not necessarily suitable for the general human head type, resulting in the spherical surface. When the lens 1' is worn on a user whose face curve is relatively flat, the center-to-face distance la' is large, and the central position of the lens 1' is greatly convex in front of the human face to cause an uncoordinated defect, and as shown in FIG. It is shown that the longitudinal section of the lens has a curved surface, causing the center 11 to protrude from the face to cause an uncoordinated loss. Another example is the cylindrical lens structure shown in the eighteenth and nineteenth figures, and the horizontal and straight cross-sectional views are respectively displayed. The cylindrical lens 2 is placed in the human body by a frame mechanism (not shown). The position of the front of the eye, and the cylindrical lens 2' can be bent to the lateral position of the human body face, can have less resistance when traveling, and its longitudinal section is plane, there is no central position 20, such as spherical convex uncoordinated situation However, since the viewing angle is generally corresponding to the angle range 2a' of the center of the eye to the obliquely below, the angle 098114322 ranges 2a, the middle direction 2b' and the vertical line 2c' of the lens 2' surface have a larger form number. A0101 Page 3 of 32 page 0982023989-0 201038994 Deviation from the angle 2d' 'causes the viewing is less clear and missing. Moreover, since the head shape of the human body is generally convex for the forehead and the concave position of the eyelid is concave, the cylindrical lens 2' does not correspond to the curvature of the human body when worn, causing the lens 2' to be closer to the forehead distance 2e, and the eyelid Distance 2f, far away, not ergonomic. US Pat. No. 60,683,376 discloses a lens and temple with a tilt joint design, and can have a new aesthetic effect, but the design only changes the angle of engagement between the pivoting portion of the lens and the temple. The lens itself is not compatible with ergonomics. A tilting pivotal portion must be provided. When the lens is disposed on the frame assembly, the frame member must be designed to have a slope pivoting portion and a mirrored joint to have the desired effect, and the applicability is still poor. The longitudinal center position of the lens is a curved surface that still has a central convex surface discomfort.

[0004] 098114322 Please refer to the seventh embodiment of the present invention, and have a rigid lens 1, a frame mechanism 2, and the lens 1 is a one-piece type, and as shown in the third figure, The lens 1 has a viewing portion 11, a portion 12 of the nose, a side portion 13 of the nose, and the viewing portion 11 corresponds to the position between the temple and the nose of the human body, and the portion 12 of the nose corresponds to the nasal position of the human body, and the lateral portion 13 is Corresponding to the position of the human temple, the viewing portion 11 has a front surface 11a and a rear surface lib. The front surface 11a is a part of a hypothetical 3D shape, and the 3D solid shape is formed by an elliptical curved top surface 14 and a top surface 14 Point 15 is connected to the circumference of the top surface 14 with a tapered body, and the first figure shows a regular elliptical cone, and the mother point 15 is located below the center of the top surface 14, and the front surface 11a is a part of the tapered surface of the cone. The front surface of the nose portion 12 and the side portion 13 of the present embodiment is also a part of the aforementioned tapered surface, and as shown in the second figure, the top edge 11c of the viewing portion 11 of the lens 1 corresponds to the vertical line of the top surface 14. 16 vertical distance la is greater than the bottom edge 1 Id It should be perpendicular to the vertical line 16 of the top surface 14 by a distance lb, and the cross section corresponding to the vertical line 16 is a straight inclined surface having an angle of 0 with the vertical line 16. As shown in the third figure, the lens 1 has a viewing portion 11 and a nose. The portion 12, the side portion 13 corresponds to the vertical line 16 in a radial direction, and the viewing portion 11, the nose portion 12 is located at the end of the elliptical short axis 141, and the side portion 13 is located at the end of the long axis 142, such that the side The square portion 13 has a larger curvature than the viewing portion 11 and the nose portion 12, and can be bent laterally corresponding to the human head, which is ergonomic.
