In view of this, the purpose of this creation is to provide a presbyopic zoom visor lens to solve the above problems.

In order to achieve the above purpose, the present invention provides a presbyopic zoom visor lens, at least including the lens body, including: a flat light zone and a zoom zone; and a shading sheet. The flat zone is located at the center of the lens, where the flat zone has no diopter. The zoom area surrounds the flat light area, and the zoom area is positive diopter. The shading sheet covers the lens body.

Among them, the shading sheet detachably covers the lens body.

Among them, the shading sheet fixedly covers the lens body.

Among them, the zoom zone has a single diopter.

Among them, the zoom zone has a plurality of diopters.

Among them, the diopters in the zoom area gradually increase from the inside to the outside.

The ratio of the diameter of the flat light zone to the width of the zoom zone is between 1:1 and 1:2.

The ratio of the diameter of the flat light zone to the width of the zoom zone is 1:1.5.

Among them, the diameter of the flat zone is 35mm.

The lens has a first surface and a second surface on opposite sides.

Wherein, the first surface and the second surface of the flat light zone have no diopter.

Wherein, the first surface of the zoom zone has no diopter, and the second surface of the zoom zone has positive diopter.

Among them, the presbyopic zoom visor lens contains two or more effective areas of the lens.

In summary, the presbyopic zoom visor lens created in this book is in line with people's habit of wearing glasses and using eyes. When looking at a distance, the flat light area is just right at the center of the pupil of the eye of the human eye. Available to see the near. In addition, this creation can effectively and fully use the flat light area of the lens as the jade area, and effectively and fully use the zoom area as the small jade area.

In order to better understand the technical features, content and advantages of this creation and the achievable effects, the creation is combined with the drawings, and the expressions of the embodiments are described in detail below. The purpose of the drawings used is only For the purpose of illustration and supplementary instruction, it may not be the true proportion and precise configuration after the implementation of the creation, so the proportion and configuration relationship of the attached drawings should not be interpreted and limited to the scope of the actual rights of the creation. In addition, for ease of understanding, the same elements in the following embodiments are described with the same symbols. Moreover, the size ratios of the components shown in the drawings are only for the convenience of explaining the elements and their structures, and are not intended to be limiting.

Please refer to the illustration. This creation is a presbyopic zoom sunshade lens 10 whose lens body 12 is made of transparent material and has a first surface 100 and a second surface 200. The second surface 200 is located on the opposite side of the first surface 100. The presbyopic zoom visor lens 10 includes a lens body 12 and a shading sheet 14. The shading sheet 14 covers the lens body 12, wherein the shading sheet 14 covers the lens body 12, for example, fixed or detachable, and can cover the first surface 100 or the second surface 200, for example. For example, the light-shielding sheet 14 may cover the lens body 12 (as shown in FIG. 1) by adhesion or plating. Alternatively, the light-shielding sheet 14 may detachably cover the lens body 12 by, for example, magnetic attraction, snapping, or hooking, whereby the user can install the light-shielding sheet 14 or remove the light-shielding sheet 14 according to needs. Wherein, the light shielding sheet 14 and the lens body 12 may have corresponding coupling members, so as to be detachably joined to each other by means of magnetic attraction, snapping or hooking. For example, the shading sheet 14 and the lens body 12 may have corresponding magnetic components, such as magnets and/or iron plates, to achieve mutual magnetic attraction.

The lens body 12 includes a flat light zone 20 and a zoom zone 30. The flat zone 20 is located at the center of the presbyopic zoom visor lens 10, and the flat zone 200 has no diopter. The zoom area 30 surrounds the flat light area 20 in a concentric manner, wherein the zoom area 30 has a positive diopter. The orthographic image of the flat area 20 is circular, and the orthographic image of the zoom area 30 is circular. The geometric center of the flat area 20 is the same as the geometric center of the zoom area 30. Both the first surface 100 and the second surface 200 of the flat area 20 have no diopter. The first surface 100 of the zoom zone 30 has no diopter, and the second surface 200 of the zoom zone 30 has positive diopter.

The zoom area 30 may be composed of a single annular area (as shown in FIG. 1 ), where the annular area has a single positive diopter, so the zoom area 30 may have a single diopter to achieve the zoom effect. Alternatively, the zoom area 30 may be composed of, for example, a plurality of annular areas having a plurality of diopters, where the diopters gradually increase from the inside to the outside, that is, gradually increase from the geometric center to the outside. For example, the dioptric power of the ring-shaped area can be increased in a stepped manner to achieve the effect of progressive zoom. The ratio of the diameter of the flat light zone 20 (orthogonal projection width) to the width of the zoom zone 30 (orthogonal projection width) is approximately 1:1 to 1:2. Among them, the comparison between the diameter of the flat light zone 20 (orthogonal projection width) and the width of the zoom zone 30 (orthogonal projection width) is preferably about 1:1.5. For example, the diameter of the flat light zone 20 is 35 mm, and the width of the zoom zone is 48 mm. The presbyopic zoom visor lens of the present invention contains two or more lens effective areas 300. In other words, in the lens effective area 300, the flat light area 20 occupies approximately one-half to two-thirds of the area. Therefore, the present invention can effectively and fully use the flat light zone 20 of the lens 10 as a jade zone, and effectively and fully use the zoom zone 30 as a small jade zone. The characteristic of this creation is that it conforms to people's habits of wearing glasses and using eyes. When looking at a distance, the flat zone 20 is just right at the center of the pupil of the eye of the human eye, which can be used to look away at the distance, and the zoom zone 30 can be used to see the near Office.

The above is only exemplary, and not restrictive. Any equivalent modifications or changes made without departing from the spirit and scope of this creation shall be included in the scope of the attached patent application.
