Embodiment approach 1

[0061] In Embodiment 1, compositions 1 to 6 were prepared according to step S920, and a control group (control group 1) was prepared separately. Table 1 shows the content of each component in each of compositions 1 to 6 and control group 1 . The difference between control group 1 and compositions 1-6 lies in the content of yellow dye and blue pigment.

[0062] [Table 1]

[0063] Table 1: Distribution ratio of each component of compositions 1 to 6 and the control group (control group 1)

[0064]

[0065] It should be noted that in Table 1, the total amount of the yellow dye and the blue pigment increases in the order of compositions 1-6, and preferably the amount of the yellow dye increases in the order of compositions 1-6. The amount of blue pigment can also be increased, but embodiments of the invention are not limited thereto. Compositions 1-6 may contain the same amount of blue pigment.

[0066] Next, step S930 will be described. In the process S930, the composition...

Embodiment approach 2

[0069] In Embodiment 2, the compositions 1 to 6 of Embodiment 1 were used in steps S930 to S950, respectively, and sterilized to form samples 1 to 6 of anti-blue light contact lenses. The control group (control group 1) was also treated under the same conditions to manufacture contact lenses of the control group (control group 1). Table 2 shows parameters used in Embodiment 2.

[0070] [Table 2]

[0071] Table 2: Manufacturing parameters

[0072]

[0073] It should be noted that in Embodiment 2, compositions 1 to 6 were used under the same conditions to form contact lenses. However, it should be understood that in each step of S930-S950 and sterilization, Compositions 1-6 can also be treated under other conditions, such as photocuring time, hydration temperature or buffer solution, which are different from those recorded in Table 2, respectively. In addition, the parameters described in Table 2 can also be used for compositions other than compositions 1-6.

Embodiment approach 3

[0093] In Embodiment 3, composition 7 was prepared according to step S920, and a control group (control group 2) was prepared separately. The yellow dye contained in composition 7 accounts for 0.13wt% of its total weight, and the blue pigment is added in such a manner that the ratio of the yellow dye to the blue pigment is 7:1. Control 2 also contained 0.13 wt% yellow dye, but no blue pigment. Next, according to steps S930-S950, using the composition 7 and the control group 2, the sample 7 of the anti-blue light contact lens and the contact lens of the control group (control group 2) were respectively manufactured and their appearances were observed. show the result in Figure 4A ~ Figure 4B .

[0094] Figure 4A The left side is a commercially available anti-UV water blue contact lens (control group 3), and the right side is an anti-blue contact lens (sample 7). Figure 4B The contact lens of the control group (control group 2) is on the left, and sample 7 is on the right...

Abstract

The present invention provides an anti-blue-light contact lens composition, which is suitable for manufacturing a contact lens having an anti-blue light function, preventing visual fatigue of a wearer, preventing visual color difference, and helping to improve the aesthetic effect. The anti-blue-light contact lens composition comprises at least one hydrogel monomer, a yellow dye, a blue pigment, a crosslinking agent, and a photoinitiator. The invention further provides a manufacturing method of the blue-light-proof contact lens. The method comprises the following steps of: providing a mold containing a male mold and a female mold; preparing a blue-proof contact lens composition containing a yellow dye and a blue pigment; injecting the composition into the female mold, and performing pressurization processing on the male mold and the female mold; performing photocuring to form a lens body; and performing hydration to form a contact lens.

Description

technical field [0001] The present invention relates to an anti-blue light contact lens, its composition and a manufacturing method, in particular to a contact lens having both anti-blue light function and aesthetic effect, its composition and a manufacturing method. Background technique [0002] With the rapid development of science and technology, 3C and electronic products have gradually become indispensable necessities in modern life. However, things like LED lights and screens of tablets, TVs, smartphones, etc. emit blue light. Therefore, when using 3C products, it is impossible to avoid the blue light emitted by the screen from entering the eyes. Blue light is the part with the strongest energy closest to the ultraviolet light wave in visible light, and its wavelength is in the range of 380nm to 530nm. Since the wavelength is shorter, it is focused in front of the retina ahead of time and is therefore prone to scatter. As a result, the eyes have to work harder to fo...
