  Hereinafter, an example of an embodiment according to the present invention will be described. The present invention is not limited to the following embodiments.

The plastic spectacle lens according to the present invention includes at least a plastic substrate.
A thermosetting resin is preferably used as a resin formed by polymerization of a monomer (polymerizable compound), which is a main material (a material having a weight ratio of more than a majority) at the time of completion of polymerization (composition) of the base material, For example, polyurethane resin, thiourethane resin, urethane-urea resin, episulfide resin, polycarbonate resin, polyester resin, acrylic resin, polyether sulfone resin, poly-4-methylpentene-1 resin, diethylene glycol bisallyl carbonate resin, or a combination thereof Is used. Further, a thermoplastic resin may be used as a main material of the base material.
Further, if at least one of a thiourethane resin and an episulfide resin is used as the material of the base material, the refractive index of the base material becomes relatively high, and the thickness can be easily reduced when correcting vision.
On the other hand, if a thermoplastic resin is used as the material of the base material, a strong base material can be easily formed.

A monoazo-based nickel complex dye is added to the base material in a weight ratio of 0.05 wt% to 0.6 wt% with respect to the main material (total weight of the polymerizable compound). The monoazo nickel complex dye is a coordination compound formed by coordination bond between a monoazo dye as a yellow dye and nickel ions. Here, a monoazo-based nickel complex dye having a maximum value of the absorptance distribution in a wavelength range of 480 nm to 520 nm is used.
Alternatively, the merocyanine dye is added to the base material in a weight ratio of 0.05 wt% to 0.8 wt% with respect to the main material (total weight of the polymerizable compound). The merocyanine dye is a synthetic dye belonging to polymethine, for example, merocyanine I, merocyanine 540, or a mixture thereof. Here, a merocyanine dye having a maximum absorption distribution in a wavelength range of 480 nm to 520 nm is used.
Alternatively, a monoazo nickel complex dye and a merocyanine dye may have a ratio of a total weight of 0.05 wt% or more and 0.8 wt% or less to the weight of the main material (total weight of the polymerizable compound) of the base material. And then added together. Preferably, the monoazo nickel complex dye and the merocyanine dye do not deviate from the above-mentioned weight ratio ranges, respectively.
By adding at least one of the monoazo nickel complex dye and the merocyanine dye, light in a wavelength range of 480 nm or more and 520 nm or less is absorbed, and light stimulation on ipRGC can be simply suppressed, thereby preventing and reducing headache. It can be easily achieved.
That is, the plastic spectacle lens including such a base material is a light blocking lens that blocks light in a wavelength range of 480 nm to 520 nm. The light shielding includes one that reduces the transmittance.

When the weight ratio is below the lower limit, the absorption of light in the wavelength range of 480 nm or more and 520 nm or less is reduced, and yellowness is suppressed, which is advantageous in terms of visibility and aesthetic appearance. Suppression of light stimulation on ipRGC by absorption of light in a wavelength range is relatively insufficient, and the effect of preventing and reducing headache is relatively insufficient.
Above the upper limit of each weight ratio described above, suppression of light stimulation on ipRGC by absorption of light in a wavelength range of 480 nm or more and 520 nm or less is sufficiently performed, and the effects of preventing and reducing headache are sufficiently exhibited. The yellowness becomes too strong and the visibility and the aesthetic appearance are relatively poor (the discomfort of the color seen through the glasses with strong yellowness is strongly recognized, and the appearance of the glasses is avoided).

In addition, from the viewpoint of protecting the eyes while ensuring visibility and further preventing the lens from deteriorating, the substrate is preferably added with an ultraviolet absorber, more preferably an ultraviolet absorber having an absorption peak wavelength of less than 380 nm. Is added. The addition amount of such an ultraviolet absorber is adjusted from the above viewpoint.
The thickness of the substrate is not particularly limited, but as the thickness increases, the internal transmittance increases in proportion, and the appearance and weight of the spectacle lens are relatively deteriorated. Therefore, the thickness is preferably 4 mm (mm) or less. It is said.

The plastic spectacle lens may be composed of only the substrate, but a hard coat film may be formed on at least one surface of the substrate.
The hard coat film is preferably formed by uniformly applying a hard coat liquid on the surface of the substrate.
Further, as the hard coat film, preferably, an organosiloxane resin containing inorganic oxide fine particles can be used. The organosiloxane resin is preferably obtained by hydrolyzing and condensing alkoxysilane. Specific examples of the organosiloxane resin include γ-glycidoxypropyltrimethoxysilane, γ-glycidoxypropyltriethoxysilane, methyltrimethoxysilane, ethylsilicate, and a combination thereof. These hydrolyzed condensates of alkoxysilane are produced by hydrolyzing the alkoxysilane compound or a combination thereof with an acidic aqueous solution such as hydrochloric acid.
On the other hand, specific examples of the material of the inorganic oxide fine particles include zinc oxide, silicon dioxide (silica fine particles), aluminum oxide, titanium oxide (titania fine particles), zirconium oxide (zirconia fine particles), tin oxide, beryllium oxide, antimony oxide, and oxide. Tungsten and cerium oxide sols may be used alone or as a mixture of two or more of them. The diameter of the inorganic oxide fine particles is preferably from 1 nm to 100 nm, more preferably from 1 nm to 50 nm, from the viewpoint of ensuring the transparency of the hard coat film. The amount (concentration) of the inorganic oxide fine particles should be at least 40% by weight (% by weight) in all the components of the hard coat film from the viewpoint of securing an appropriate degree of hardness and toughness in the hard coat film. Preferably, it occupies not more than weight%. In addition, at least one of a metal salt of acetylacetone and a metal salt of ethylenediaminetetraacetic acid can be added to the hard coat liquid as a curing catalyst. A) A surfactant, a colorant, a solvent, and the like can be added as necessary for imparting a transparent color.
As the inorganic oxide (metal oxide) in the inorganic oxide fine particles, one that does not absorb as much as possible in the visible region is selected to secure a high transmittance over the entire visible region, and to be visually recognized when the lens is worn with respect to the visible color with the naked eye. From the viewpoint of securing a state in which the color difference is extremely small, it is preferable that the oxide is one or more metal oxides excluding Ti and Ce. Since oxides of Ti (titanium) and oxides of Ce (cerium) absorb in the visible region (especially on the short wavelength side), they are excluded from the preferred metal oxides. Examples of such preferred metal oxides include Sb (antimony), Zr (zinc), Sn (tin), Si (silicon), Al (aluminum), Ta (tantalum), La (lanthanum), and Fe (iron). , Zn (zinc), W (tungsten), Zr (zirconium), or In (indium) oxide, or a combination thereof.
The physical thickness of the hard coat film is preferably 0.5 μm (micrometer) or more and 4.0 μm or less. The lower limit of this film thickness range is determined because it is difficult to obtain a sufficient hardness if it is thinner than this. On the other hand, with respect to the upper limit, when the thickness is larger than this, the possibility of problems related to physical properties such as cracks and brittleness increases dramatically, and the influence of absorption (decrease in transmittance) of the inorganic oxide fine particles in the visible region is increased. It is determined from heightening.
Further, a primer film may be added between the hard coat film and the substrate surface from the viewpoint of improving the adhesion of the hard coat film. Examples of the material of the primer film include a polyurethane resin, an acrylic resin, a methacrylic resin, an organosilicon resin, and a combination thereof. The primer film is preferably formed by uniformly applying a primer solution to the surface of the substrate. The primer liquid is a liquid obtained by mixing the above resin material and inorganic oxide fine particles in water or an alcohol-based solvent.

An optical multilayer film may be added to the plastic spectacle lens. The optical multilayer film may be formed on a substrate, but is preferably formed on a hard coat film. The optical multilayer film is formed on at least one surface of the substrate, and when formed on both surfaces, preferably, both films have the same laminated structure.
The optical multilayer film is formed from the viewpoint of ensuring an anti-reflection function (anti-reflection film), preferably to have a flat and high transmittance distribution over the entire visible region.
The optical multilayer film is preferably formed by alternately laminating low-refractive index layers and high-refractive index layers from the viewpoint of ensuring an antireflection function, and is preferably an odd-numbered layer as a whole (all 5 layers, total 7 layers). Etc.). More preferably, assuming that the layer closest to the substrate (the layer closest to the substrate) is the first layer, the odd-numbered layers are low-refractive-index layers and the even-numbered layers are high-refractive-index layers.
The low-refractive-index layer and the high-refractive-index layer are formed by a vacuum evaporation method, an ion-assisted evaporation method, an ion plating method, a sputtering method, or the like.

  In the plastic spectacle lens of the present invention, an intermediate film other than a hard coat film and another type such as an antifouling film (water-repellent film / oil-repellent film) are provided between the optical multilayer film and the substrate and / or at least one of the surfaces of the optical multilayer film. In the case where the optical multilayer film is formed on both sides, the kind of another film to be added may be changed, or the presence or absence of the film may be changed.

  Further, the plastic spectacle lens may be added with at least one of a blue dye and a violet dye in order to moderate or cancel yellow mainly due to addition of at least one of a monoazo nickel complex dye and a merocyanine dye. .

Further, using the above-mentioned plastic spectacle lens, spectacles that can simply suppress light stimulation to ipRGC and that can easily prevent and reduce headache are manufactured.
These glasses are light-shielding glasses using light-shielding lenses.

FIG. 1 shows the spectral transmittance distributions of Examples 1 to 3 in the visible region (wavelengths from 380 nm to 780 nm). The visible range may be set in various ways, such as a lower limit of 400 nm or an upper limit of 750 nm.
In Examples 1 to 3, a minimum value of the transmittance distribution, that is, a maximum value of the absorptance distribution exists at a wavelength of 505 nm, which is in a wavelength range of 480 nm to 520 nm. The minimum value of the transmittance distribution is about 38% in Example 1, about 25% in Example 2, and about 17% in Example 3. In addition, although the absorptivity (%) = 100−transmittance (%) − reflectance (%), the reflectance in the visible region is at most 3%, and in Example 1, the reflection is prevented. Therefore, it is within 1% and can be neglected, that is, absorption rate (%) ≒ 100−transmission rate (%).
Further, in Examples 1 to 3, a transmittance of 70% or more is secured in a short wavelength range of 410 nm to 430 nm, and a transmittance of about 90% is secured in a long wavelength range of 510 nm to 780 nm. Visibility is ensured while achieving cut (suppression) of transmitted light in a wavelength range of 480 nm to 520 nm.

A similar study was conducted for the same 10 migraine patients for 4 weeks without wearing the glasses according to Example 1 ("before wearing" in FIGS. 2 and 3). In FIG. 3, the degree of headache is shown by averaging the total points of each of the 10 subjects on 1/3 day.
The average night driving time was 38 minutes before wearing and 34 minutes after wearing.

As shown in FIG. 2A, the number of headache days was significantly reduced from 8.7 days before wearing the glasses according to Example 1 to 7.0 days during wearing (p value <0.05). ).
In addition, as shown in FIG. 2A, the number of medication days decreased from 5.4 days before wearing the glasses according to Example 1 to 4.5 days during wearing.
Further, as shown in FIG. 3, the degree of headache decreased from 4.3 before wearing in the morning to 4.1 during wearing, to 95.3% before wearing, and in the afternoon, 4.3. From 9 to 4.3 during wearing, it decreased to 87.8% before wearing, and at night, from 5.3 before wearing to 3.2 to 60.4% before wearing, it was greatly reduced.
According to such an evaluation, it can be said that headache is suppressed by Example 1.
The transmittance distribution is the same as that of the first embodiment. In the second and third embodiments, the transmittance of which is slightly smaller in the entire visible region than in the first embodiment, the visibility at the time of mounting is slightly inferior to that of the first embodiment. A headache suppressing effect equal to or higher than that of Example 1 is sufficiently exhibited.
