Description

Glasses lens having near-infrared blocking and antibiotic property}

The present invention relates to spectacle lenses, and more particularly, to spectacle lenses having anti-bacterial and near-infrared blocking, UV blocking and blue light blocking effects.

It is known that certain spectral ranges can damage the human eye if they are radiated to the eye at high intensities or with relatively long exposure durations. The cornea, lens and retina are particularly sensitive. With such a specific spectrum, the danger in the ultraviolet spectrum range is known in the prior art, and spectacle lenses having a protective effect thereon are also commercially available.

However, due to changes in the surrounding environment in recent years, exposure to wavelength bands other than ultraviolet rays, especially near infrared rays, is increasing. For example, an infrared emitter provided in a lamp mounted in various areas such as cameras such as CCTV or automobiles is one example.

A person's pupils open wide when it is dark, and infrared radiation from these lamps can be directly incident on the retina. However, as infrared radiation does not reduce the pupil or activate the protective reflex response of the eye that closes the eyelids, within a range of these environmental conditions the eye may be at risk. In particular, since conventional spectacle lens materials have a low absorption action in the range of 800 nm to 1500 nm, it is difficult to exert any protective effect on light in the near-infrared region through conventional spectacle lenses.

Light in the near-infrared wavelength band can further aggravate eye diseases caused by heat, wrinkles, and photoaging.

On the other hand, spectacle lenses can serve as a primary barrier to prevent various pathogens from entering the wearer's eyes directly from the external environment. There is a constant risk of human infection through hands.

Accordingly, there is an urgent need to develop spectacle lenses capable of blocking light in the near-infrared wavelength band and protecting the wearer from various pathogens.

Unexamined Patent Publication No. 2017-0022936

In addition, the thickness of the coating reinforcement layer is 10 ~ 30㎚, aluminum oxide may be included in an amount of 18 ~ 25 parts by weight based on 100 parts by weight of silicon dioxide.

According to the present invention, while having an antibacterial function against pathogenic microorganisms such as Staphylococcus aureus and Escherichia coli, it is possible to significantly reduce the manufacturing man-hours and manufacturing cost. In addition, by effectively blocking the light in the near-infrared wavelength band, it is possible to prevent various eye diseases and skin diseases that may occur depending on the degree of exposure by the heat action of the near-infrared rays, and it is also possible to prevent skin aging and wrinkles caused by the light and heat action. .

In addition, the surface of the spectacle lens according to an embodiment of the present invention can express a super water-repellent surface, and at the same time, the super water-repellent surface can last for a long time.

Hereinafter, embodiments of the present invention will be described in detail so that those of ordinary skill in the art to which the present invention pertains can easily implement them. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

The spectacle lens according to the present invention includes a lens substrate, an antireflection layer coated on one or both surfaces of the lens substrate, and an antibacterial layer deposited on the outside of the antireflection layer, and may further include a super water-repellent layer on the outside of the antibacterial layer .

The lens substrate may be applied without limitation in the case of conventional spectacle lenses. The lens base material may be prepared by a conventional manufacturing method of mixing a monomer, a polymerization initiator, a dye, an additive, etc. and stirring it to prepare a mixed solution, vacuum defoaming the mixed solution, and injecting it into a mold for molding. In addition, in order to improve the immersion efficiency in the process of manufacturing the lens substrate, thermal polymerization may be performed by dividing the temperature range into 5 to 8 sections and varying the temperature change rate.

As the monomer, any one or more of an acrylic monomer, an acrylate-based monomer, a styrene-based monomer, an allyl carbonate-based monomer, an episulfide-based monomer, and a urethane-based monomer may be used. In addition, since the polymerization initiator may be appropriately selected and used according to the type of the selected monomer, the present invention is not particularly limited thereto.

In addition, the lens substrate may include a dye, and the dye may include at least one of a UV blocking dye, a blue light blocking dye, and an infrared blocking dye. As these dyes, a dye known in the optical field may be used in consideration of the wavelength band of light to be blocked or absorbed. For example, the UV-blocking dye may use a benzotriazole-based UV absorber having a molecular weight of 250 to 330 g/mol for UV-A blocking, typically 2-(2-hydroxy-5-tert-octylphenyl)- 2H-benzotriazole, 2-(5-tert-butyl-2-hydroxyphenyl)-2H-benzotriazole, 2-(5-tert-octyl-2-hydroxyphenyl)-2H-benzortriazole, etc. are mentioned. In addition, for UV-B blocking, a benzotriazole-based UV absorber having a molecular weight of 300 to 320 g/mol can be used, typically 2-(3-tert-butyl-2-hydroxy-5-methylphenyl)-5 -chloro-2H-benzotriazole, 2-(5-chloro-2H-benzotriazole-2-yl)-6-(1,1-dimethylethyl)-4-methyl-Phenol, 2-tert-butyl-6-(5- and chloro-2H-benzotriazol-2-yl)-4-methylphenone. In addition, for the UV-C blocking, a benzotriazole-based UV absorber having a molecular weight of 430 to 450 g/mol may be used, and typically 2-(2H-Benzotriazol-2-yl)-6(1-methyl- 1-phenylethyl)-4-(1,1,3,3-tetramethylbutyl)phenol and the like.

In addition, the infrared blocking dye may be, for example, (quater) rylene, phenylenediamine or a class of materials of a metal complex having an appropriate charge transfer transfer. Specifically (bis(4,4'-dimethoxydithiobenzyl)nickel, bis(4-dimethylaminodithiobenzyl)nickel), N,N,N',N'-tetrakis(4-dibutylaminophenyl) )-p-phenylenediaminium hexafluorophosphate, anthra[9”,1”,2”:6,5,10;10”,5”,6”:6’,5’,10’] dianthra [2,1,9-def:2',1',9'-d'e'f'] diisoquinoline-1, 3,12,14(2H,13H), anthra[9",1", 2”:6,5,10;10”,5”,6”:6’,5’,10’] dianthra[2,1,9-def:2’,1’,9’-d’e 'f']diisoquinoline-1,3,12,14(2H,13H)-tetron, 2,13-bis[2,6-bis(1-methylethyl)phenyl]-5,10,16, 21-tetrakis[4-(1,1,3,3-tetramethylbutyl)phenoxy] and the like can be used.

The above-described dye may be contained in an amount of 0.05 to 10 parts by weight based on 100 parts by weight of the monomer, but the present invention is not particularly limited thereto, and may be appropriately changed in consideration of the desired blocking effect and light transmittance.

An anti-reflection layer is provided on one or both surfaces of the above-described lens substrate, and the anti-reflection layer includes a first anti-reflection layer performing an anti-reflection function and a second anti-reflection layer performing an anti-reflection and near-infrared blocking function.

The first anti-reflection layer is a low refractive index layer having a refractive index of less than 1.5 and a high refractive index layer having a refractive index of 1.5 to 2.0 in a thickness range of 5 to 50 nm from the surface side of the lens base material. It has a structure in which the layers are arranged. The first anti-reflection layer may be composed of 3 to 7 layers, and a low refractive index layer is disposed on the uppermost layer corresponding to the outermost of the first anti-reflection layer.

In addition, the first antireflection layer includes a low refractive index layer having a refractive index of less than 1.5 and a high refractive index layer having a refractive index of 1.5 to 2.0. All materials of the high refractive index layer may be the same, or one layer may be substituted with a layer made of another material that satisfies the refractive index condition.

The low refractive index layer may be used without limitation in the case of a material having a refractive index of less than 1.5 and used in the optical field. For example, the low refractive index layer may include at least one of a low refractive index layer made of silicon dioxide and a low refractive index layer made of SV 20 . Here, SV 20 is commercially available as a trade name.

In addition, the high refractive index layer may be used without limitation in the case of a material having a refractive index of 1.5 to 2.0 and used in the optical field. For example, the high refractive index layer may be one or more metal oxides selected from the group of oxides of Zr, Al, Y, Ta, Nd, La, Nb and PrTi or combinations thereof, preferably made of a zirconium oxide layer. It may be any one or more of a high refractive index layer, a high refractive index layer made of EU 3, and a high refractive index layer made of SV 50. Here SV 50 and EU 3 are commercially available as trade names.

In addition, the low refractive index layer and the high refractive index layer may be configured such that the low refractive index layer and the high refractive index layer are alternately stacked from the surface of the lens base material so that the uppermost layer is positioned such that the low refractive index layer is located.

In addition, the low-refractive-index layer and the high-refractive-index layer are designed to have a predetermined thickness within a thickness range of 5 to 50 nm. For example, a first low refractive index layer, which is silicon dioxide deposited to a thickness of 30±10 nm on the surface of the lens substrate. , a first high refractive index layer of zirconium oxide deposited to a thickness of 20±10 nm, a second low refractive index layer of silicon dioxide deposited to a thickness of 50±10 nm, a second high refractive index of zirconium oxide deposited to a thickness of 40±10 nm and a third low-refractive-index layer of silicon dioxide deposited to a thickness of 15±10, which may be advantageous in achieving a desired anti-reflection function.

Next, a second anti-reflection layer is disposed outside the first anti-reflection layer. The second anti-reflection layer is a high refractive index layer having a thickness of 80 to 120 nm and a refractive index of 1.5 to 2.0, a low refractive index layer having a thickness of 130 to 170 nm and a refractive index of less than 1.5 sequentially arranged outside the first anti-reflection layer; and It includes a high refractive index layer having a thickness of 80 to 120 nm and a refractive index of 1.5 to 2.0, and through this, it is advantageous to express a near-infrared blocking property along with an anti-reflection property. If it is combined with the first anti-reflection layer and the layer is designed outside these thickness ranges, it may be difficult to express the desired anti-reflection properties and near-infrared blocking properties.

The second anti-reflection layer has a thickness of 80 to 120 nm and a refractive index of 1.5 to 2.0, a high refractive index layer, a thickness of 130 to 170 nm and a refractive index of less than 1.5, and a thickness of 80 to 120 nm and a refractive index of 1.5 to 2.0. The phosphorus high refractive index layer may be formed, or these three layers may be repeatedly laminated two or more times to form one unit.

In the second anti-reflection layer, the low refractive index layer may be a silicon dioxide layer, and the high refractive index layer may be a zirconium oxide layer, which is advantageous to achieve a synergistic effect in the expression of near-infrared blocking properties. On the other hand, it may be considered that a titanium dioxide layer is included as the high refractive index layer. In this case, it may be difficult to achieve sufficient blocking performance in a wavelength band of 800 to 1000 nm.

In addition, an antibacterial layer is disposed on the outside of the above-described second anti-reflection layer. The antibacterial layer may be formed of a known antibacterial material employed in the optical field. However, it may be a layer formed through deposition to reduce the manufacturing time and number of manufacturing processes by being formed together during the deposition process for forming the anti-reflection layer, and may include an antibacterial material suitable for deposition. The deposition may be, for example, vacuum deposition. In addition, the antibacterial layer may include any one or more of silver or silver ions, copper oxide, and zinc oxide.

The antibacterial layer may have a thickness of 5 to 30 nm, which may be advantageous in expressing a desired antibacterial function without inhibiting light transmittance.

In addition, it may further include a super water-repellent layer outside the antibacterial layer. The super water-repellent layer may be used without limitation in the case of a known super water-repellent layer employed in optical materials such as lenses. The super water-repellent layer may include, for example, any one or more of an alkoxide-based silane compound and a fluorosilane compound. Specifically, the alkoxide-based silane compound and the fluorosilane compound include tetramethoxysilane, tetraethoxysilane, tetranormal isopropoxysilane, tetraisopropoxysilane, tetranormal butoxysilane, tetraisobutoxysilane, and methyltrimethoxysilane. , ethyltrimethoxysilane, normalpropyltrimethoxysilane, hexyltrimethoxysilane, octyltrimethoxysilane, decyltrimethoxysilane, phenyltrimethoxysilane, vinyltrimethoxysilane, methyltriethoxysilane, Ethyltriethoxysilane, normalpropyltriethoxysilane, hexyltriethoxysilane, octyltriethoxysilane, decyltriethoxysilane, phenyltriethoxysilane, vinyltriethoxysilane, trifluoropropyltrimethoxy Silane, tridecafluorooctyltrimethoxysilane, heptadecafluorodecyltrimethoxysilane, heptadecafluorodecyltriethoxysilane, dimethyldimethoxysilane, diethyldimethoxysilane, dimethyldimethoxysilane, diethyl It may include at least one of diethoxysilane, diphenyldimethoxysilane, diphenyldiethoxysilane, trimethylmethoxysilane, triethylmethoxysilane, trimethylethoxysilane, and triethylethoxysilane.

On the other hand, the super water-repellent layer including at least one of an alkoxide-based silane compound and a fluorosilane compound is formed on the antibacterial layer, and there is a fear that peeling occurs during use. Accordingly, a coating reinforcement layer may be further included between the antibacterial layer and the super water-repellent layer. The coating-reinforced layer may include silicon dioxide and aluminum oxide, and the layer formed through deposition of these materials may have a microporous structure, so it may be advantageous to enhance the coatability and adhesion of the super water-repellent layer. have. In addition, the thickness of the coating reinforcing layer may be 10 ~ 30㎚, through this may not inhibit light transmission. In addition, the coating reinforcing layer may contain 18 to 25 parts by weight of aluminum oxide based on 100 parts by weight of silicon dioxide. Adhesion, durability can be difficult to achieve. In addition, when the amount of aluminum oxide exceeds 25 parts by weight, it may be difficult to form a layer having a microporous structure, and thereby the coating property and durability of the super water-repellent layer including the alkoxide-based silane compound and the fluorosilane compound is lowered there is a risk of becoming

On the other hand, according to an embodiment of the present invention, it is possible to form a super water-repellent coating after coating the ionic liquid on the coating reinforcement layer, there is an advantage that can achieve the increased durability of the super water-repellent coating layer through this. The ionic liquid is 1-butylpyridinium hexafluorophosphate, 1-butyl-3-methylpyridinium tetrafluoroborate, 1-butyl-3-methylpyridinium trifluoromethanesulfonate, 1-butyl- 3-methylpyridiniumbis(trifluoromethanesulfonyl)imide, 1-butyl-3-methylpyridiniumbis(pentafluoroethanesulfonyl)imide, 1-hexylpyridiniumtetrafluoroborate, 2 -Methyl-1-pyrrolinetetrafluoroborate, 1-ethyl-2-phenylindoletetrafluoroborate, 1,2-dimethylindoletetrafluoroborate, 1-ethylcarbazoletetrafluoroborate and 1-ethyl It may include one or more selected from the group consisting of -3-methylimidazolium tetrafluoroborate, and more preferably, the liquid may be 1-butylpyridinium hexafluorophosphate.

Hereinafter, the present invention will be described in more detail through examples, but the following examples are not intended to limit the scope of the present invention, which should be construed to aid understanding of the present invention.

A commercially available spectacle lens base material that does not contain infrared blocking dye was prepared. Thereafter, an anti-reflection coating layer was formed by depositing on one surface of the spectacle lens base under the conditions of Table 1 below. After that, the anti-reflection coating layer was vacuum-deposited to a thickness of 15 nm to form an Ag antibacterial layer, and a super water-repellent coating solution prepared through the following preparation example was prepared on the Ag antibacterial layer, and then spin-coated on the surface of the Ag antibacterial layer 25 After drying at °C for 30 minutes, the temperature was raised at a rate of 10 °C/min and heat treatment was performed at 140 °C for 1 hour to prepare a spectacle lens having a super water-repellent coating layer.

<Experimental Example 1>

For the spectacle lenses according to Example 1 and Comparative Examples 1 and 2, the near-infrared transmittance of a wavelength of 900 to 1000 nm and a band of 1300 to 1400 nm was measured using a U-4100 spectrometer, and the maximum transmittance within the wavelength range is shown in the table below. 4 is shown.

As can be seen from Table 4, it can be seen that in the case of the spectacle lens according to Example 1, the transmittance of the near-infrared wavelength band is lower than that of the spectacle lens according to Comparative Examples 1 and 2, so that the blocking function is excellent.

<Example 2>

It was manufactured in the same manner as in Example 1, but a coating reinforcement layer made of silicon dioxide was vacuum-deposited to a thickness of 20 nm between the antibacterial layer and the super water-repellent layer to prepare spectacle lenses as shown in Table 5 below.

<Example 3>

It was prepared in the same manner as in Example 1, but a coating reinforcing layer made of aluminum oxide between the antibacterial layer and the super water-repellent layer was vacuum-deposited to a thickness of 20 nm to prepare spectacle lenses as shown in Table 5 below.

<Example 4>

It was prepared in the same manner as in Example 1, but between the antibacterial layer and the super water-repellent layer, the coating reinforcement layer was vacuum-deposited to a thickness of 20 nm so that 19 parts by weight of aluminum oxide was contained in 100 parts by weight of silicon dioxide, as shown in Table 5 below. lenses were manufactured.

<Experimental Example 2>

The contact angle on the super-water-repellent layer side of the spectacle lens surface according to Examples 1 to 4 was measured using a contact angle measuring device. Thereafter, the contact angle was measured after the spectacle lens was left in a constant temperature and humidity chamber at 90° C. and a relative humidity of 95% for 200 hours. In this case, the contact angle was measured at five points and calculated as the average value thereof was used.

The spectacle lenses of Examples 1 to 4 were measured to have an initially measured contact angle of 120°.

As can be seen from Table 5, in the case of Example 1 without a coating reinforcing layer, it can be seen that the reduction rate of the contact angle of the super water-repellent layer reaches 35.1% under poor conditions of high temperature and high humidity. However, when the coating reinforcing layer is provided, the durability of the super water-repellent layer is improved, and in particular, it can be seen that in the case of Example 4, the durability of the super water-repellent layer is very excellent.
