Problems solved by technology

That is, if the value as a personal item such as fashion and decoration is not recognized, then even if the function is excellent, such glasses are just a prop to supplement the body function, and cannot be said to be suitable for the user's daily use.
[0005] Also, props that are only used to compensate for a specific dysfunction and are not suitable for users who do not have such a dysfunction have poor marketability and high cost, making it difficult for users who need such props to purchase to the prop

no. 2 Embodiment approach

[0107] Figure 18 (a) The spectacle lens 100a of 2nd Embodiment is shown using the front view seen from the object side. in addition, Figure 18 (b) shows the light-shielding rate distribution achieved by the light-shielding layer 20 . This spectacle lens 100a also has a high translucency region 12 including the eye point 11, and a low translucency region 14 arranged to surround the entire circumference of the high translucency region 12, and the light shielding ratio of the low translucency region 14 is The high translucency region 12 is high and includes a region (gradient region) 16 in which the light shielding ratio increases toward the periphery 15 . The dotted line indicating the boundary 13 between the high translucency region 12 and the low translucency region 14 is an imaginary line and does not actually appear. The spectacle lens 100a is also as figure 1 as well as figure 2 As shown, it can be attached to the spectacle frame 9, and it is possible to provide the...

no. 3 Embodiment approach

[0111] Figure 19 The distribution (change) of the light-shielding ratio of the light-shielding layer 20 of the spectacle lens 100b of the third embodiment is shown. This spectacle lens 100b also has a high translucency region 12 including the eye point 11, and a low translucency region 14 arranged to surround the entire circumference of the high translucency region 12, and the low translucency region 14 is shielded from light. The light-shielding ratio is higher than that of the high-transmittance region 12, and there is a region (gradient region) 16 in which the light-shielding ratio changes toward the periphery 15. However, in this spectacle lens 100b, the gradient region 16 of the low translucency region 14 includes the vicinity 17 of the boundary (full circumference) 13 between the gradient region 16 and the high translucency region 12, and the color is compared toward the periphery 15. A region 16 a that gradually becomes darker sharply; and, outside this region 16 a , ...

Abstract

An object of the present invention provides a fashionable eyeglass lens of which is has a gradient color density. The technical solution of the lens is that the lens (10) includes: a high light-transmissive region (central part of the lens) (12) including an eyepoint (position of the eye when eyeglasses is worn, center position of pupil) (11); and a low light-transmissive region (periphery of the lens) (14) surrounding the entire circumference of the high light-transmissive region, a light blocking ratio in the low light-transmissive region (14) being higher than the light blocking ratio in the high light-transmissive region(12), wherein the low light-transmissive region (14) has a region where the light blocking ratio changes toward the periphery (15).

Description

technical field [0001] The present invention relates to spectacle lenses. Background technique [0002] Patent Document 1 describes a technique for increasing the light transmittance at the central portion of an eyeglass lens and reducing the light transmittance at the peripheral portion thereof. Furthermore, in order to achieve the above object, it is described that a mirror coating layer forming a semi-mirror is provided on the front surface of the mirror part, and a plate having a through hole is attached to the rear face of the mirror part. For the glasses, the light transmittance in the center of the lens part of the glasses is high, so people can see objects clearly through the high transmittance part in the center of the lens. The efficiency partially reduces the amount of light entering the eyes, which can effectively protect the eyes from light damage, and when the eyes suffer from cataracts, it can reduce the diffuse reflection of light in the peripheral part of t...
