Such a polarizing layer may be a polarizing film containing iodine, a dye (especially a dichroic dye), etc.

[0128] The spectacle lenses of this disclosure may further have a layer X2.

This ratio (Zr / Ti) can be controlled, for example, by adjusting the deposition conditions using conventional methods.

[0131] Eyeglasses equipped with the eyeglass lenses of this disclosure are also included in the technical scope of this disclosure. [Examples]

[0132] The present invention will be further described in detail by the following examples, but the present invention is not limited thereto.

[0133] Synthesis Example 1 100 parts by mass of Takenate (manufactured by Mitsui Chemicals, Inc.), 37 parts by mass of 4,4'-methylenebis(2-chloroaniline), 0.0096 parts by mass of a dye having a tetraazaporphyrin skeleton ("TAP2", manufactured by Yamada Chemical Co., Ltd.), and 0.29 parts by mass of KEMISORB 111 (manufactured by Chemipro Chemical Co., Ltd.) were mixed, heated at 80°C for 24 hours, and then cooled to obtain base material 1.

[0134] Example 1 In the example synthesis, the substrate 1 was prepared by adjusting the metal content (excluding silicon atoms) so that the CPS ratio (Ti:Zr:Sn) of X-ray photons attributed to Ti, Zr, and Sn in X-ray fluorescence analysis was 91.7:7.1:1.2. A liquid composition containing these elements was prepared, coated, and cured to obtain an eyeglass lens 1 having layer X1. The spherical power S was adjusted to -0.25D, and the visible light transmittance was set to 60%.

[0135] Example 2 In the example synthesis, the substrate 1 was prepared by adjusting the metal content (excluding silicon atoms) so that the CPS ratio (Ti:Zr:Sn) of X-ray photons attributed to Ti, Zr, and Sn in X-ray fluorescence analysis was 91.3:7.6:1.1. A liquid composition containing these was prepared, coated, and cured to obtain an eyeglass lens 2 having layer X1 (spherical power S is -0.25D, visible light transmittance is 60%).

[0136] Comparative Example 1 In the example synthesis, the substrate 1 was prepared by adjusting the metal content (excluding silicon atoms) so that the CPS ratio (Ti:Zr:Sn) of X-ray photons attributed to Ti and Sn in X-ray fluorescence analysis was 16.3:83.7. A liquid composition containing these was prepared, coated, and cured to obtain an eyeglass lens 3 having layer X1 (spherical power S is -0.25D, visible light transmittance is 60%).

[0137] Comparative Example 2 In the synthesis example, a liquid composition containing only silicon atoms as the metallic component was prepared on the substrate 1 obtained, and this was applied and cured to obtain an eyeglass lens 4 having layer X1 (spherical power S is -0.25D, visible light transmittance is 60%).

[0138] (Method for measuring specific elements) The eyeglass lenses were analyzed using an X-ray fluorescence analyzer (Hitachi High-Tech Science Corporation, EA6000VX) under the following conditions. Tube target element: Rh Measurement time: 100 seconds Validity period: 55 seconds Collimator: 1.2 x 1.2 mm Excitation voltage (kV): 50 Tube current: 670μA Filter: OFF Focus: Standard Atmosphere: Atmosphere Peaking time: 1.0 μsec Quantitative conditions (analytical method): Bulk FP

[0139] The results of the X-ray fluorescence analysis are shown in the table below.

[0140] [Table 1]

[0141] <Vision Test> The visual acuity of subjects with normal vision was measured in a measurement room while wearing eyeglass lenses 1-4 obtained in the examples and comparative examples. The environment in the measurement room was set to an illuminance of 400 lux, which is slightly dimmer than a normal room, and 60 lux, which simulates nighttime.

[0142] Seven adult men and women with uncorrected visual acuity ranging from 0.6 to 1.2 were selected as subjects, and the results of the visual acuity test conducted on these subjects are shown in Table 1 below. Table 2 shows the results at an illuminance of 400 lux, and Table 3 shows the results at an illuminance of 60 lux. The visual acuity when wearing the lens of this application was defined as "lens-wearing visual acuity." An evaluation score of +1 was assigned for every +0.1 difference between the uncorrected visual acuity and the lens-wearing visual acuity (lens-wearing visual acuity - uncorrected visual acuity), and an evaluation score of -1 was assigned for every -0.1 difference, to compare the effect of wearing the lens. A higher evaluation score means that visual acuity is improved by wearing the lens. On the other hand, a lower evaluation score means that the effect of improving visual acuity by wearing the lens is low, or conversely, that visual acuity is decreased by wearing the lens. The evaluation values ​​and average values ​​for each example or comparative example are also shown in Tables 2 and 3.

[0143] [Table 2]

[0144] [Table 3]

[0145] As can be seen from the results in Tables 2 and 3, in Examples 1 and 2, a certain improvement in visual acuity was observed even under low light conditions (dark field). Therefore, it can be said that wearing the eyeglass lenses of this disclosure can achieve both visibility and anti-glare properties while maintaining the contrast of the field of view. On the other hand, no improvement in visual acuity was observed in Comparative Examples 1 and 2.

[0146] Example 3 A multi-coat layer, layer X2, was formed on the spectacle lens 1 obtained in Example 1 by vapor deposition to obtain a spectacle lens 5. The relative amounts of Zr and Ti contained in layer X2 were measured by X-ray fluorescence analysis, and the ratio of X-ray photons attributed to Zr to those attributed to Ti (Zr / Ti) was 0.032.

[0147] Comparative Example 3 A multi-coat layer, layer X2, was formed on the spectacle lens 3 obtained in Comparative Example 2 by vapor deposition to obtain a spectacle lens 6. The relative amounts of Zr and Ti contained in layer X2 were measured by X-ray fluorescence analysis, and the ratio of X-ray photons attributed to Zr to those attributed to Ti (Zr / Ti) was 0.022.

[0148] Similarly, visual acuity tests were performed on eyeglass lenses 5 and 6 obtained in Example 3 and Comparative Example 3. Table 4 shows the results at an illuminance of 400 lux, and Table 5 shows the results at an illuminance of 60 lux.

[0149] [Table 4]

[0150] [Table 5]

[0151] As can be seen from the results in Tables 4 and 5, it was confirmed that forming layer X2 has the effect of further improving visual acuity even in low light conditions. From this, it can be said that by providing layer X2, it is possible to achieve both visibility and anti-glare properties while maintaining the contrast of the field of view even in dark fields.
