Detailed ways

The specific embodiments of the present invention are further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

1 to 3, an AR optical mask lens includes a curved panel 1 and a plurality of buckles 2 evenly distributed along an edge of the curved panel 1, the curved panel 1 includes a body and an arc portion 12 extending from both sides of the body, the body and the curved portion 12 are enclosed as a semi-closed receiving space, and the thickness and the radius of the curved panel 1 are from the curved portion 12 toward the body The thickness of the curved portion 12 ranges from 1.32 to 2.31 mm, and increases from one end away from the body to the other end adjacent to the body. The thickness of the body ranges from 2.31 to 2.35 mm. Since the thickness of the AR optical mask lens of the present invention is variable, the AR optical mask lens of the present invention can reduce or eliminate distortion by an unequal curvature (ie, free curvature) AR optical mask lens design, thereby making the image Clear, and then people will not dizzy when used for a long time.

The body includes a first body 11 disposed adjacent to the curved portion 12 and a second body 10 disposed away from the curved portion 12, the first body 11 having a thickness from an end near the curved portion 12 to a distance The other end of the curved portion 12 is sequentially increased, and the thickness of the second body 10 is successively decreased from one end near the curved portion 12 to the center line of the second body 10. It should be noted that in the preferred embodiment of myopia described herein, in other embodiments, the wavy curved panel 1 can also be obtained according to the refractive index experiment, even if the thickness of the curved panel 1 is not sequentially increasing or decreasing, but The curved panel 1 is divided into a plurality of small segments, and the thickness of each segment can have several thickness values which are not much different, and each segment is formed to form a wave-shaped curved panel 1. For example, if the curved panel is divided into N small segments, the thickness of the N-1 segment is assumed to be a value a, and the thickness of the N-2 segment and the N segment may be greater than a, but the curvature of the curved panel 1 The overall trend is also increasing or decreasing in order. This can reduce or eliminate distortion and thus the image is clear.

The inner wall of the body has a radius of curvature ranging from 6.3 to 432.3 mm, and the outer wall has a radius of curvature ranging from 6.0 to 531.3 mm, and both are from the end of the first body 11 near the curved portion 12 to the center line of the second body 10. Decrement after incrementing. The radius of curvature of the inner wall of the curved portion 12 ranges from 6.3 to 11.1 mm, and the radius of curvature of the outer wall ranges from 6.0 to 11.5 mm, and both from the end of the curved portion 12 away from the first body 11 to the first body 11 The other end is first decremented and then incremented. The same as the thickness, the different thicknesses can be adjusted by spacing, so that the aforementioned wavy curved panel 1 has a smoother line and a better external touch, which can better eliminate distortion.

The buckle 2 is disposed to protrude from the curved panel 1. The buckle 2 includes a slider extending perpendicularly to the curved panel 1 and a recess recessed from a side of the slider toward the interior of the slider.
