专利摘要:
A colored contact lens (10) having blue and anti-UV light filtering functions is a three-layer processed contact lens in which an intermediate layer coloring agent (12) is cured on a lens of the lower layer (13), and the upper layer lens (11) contains a UV light absorber (ultraviolet) and a blue light filtering film agent.

专利说明:

[0001] The present invention relates to a colored contact lens having functions for filtering blue light and anti-UV, and more particularly, providing a lens. contact which also has the function of filtering blue light and has an anti-UV (ultraviolet) capability. Classic sunglasses are able to filter the UV (ultraviolet) rays of the sun, and also have a slight blue light filtering effect of about 10%. However, in general, people do not wear sunglasses indoors when using a computer because it would be too obscure to clearly see the computer screen. Therefore, people usually wear sunglasses only outdoors and wear glasses with blue light filter on the inside. In addition, glasses claiming to have variable shade transition lenses primarily include the integration of a UV filtering function into the myopia correction lenses, but do not allow a blue light filtering effect. In addition, screens of mobile phones, computers and touch-sensitive tablets all emit blue light. Blue light is the strongest color of visible light, and looking directly and excessively at the blue light for a long time damages the macula part of the eyes and the retinal cells, causing lesions. In addition, blue light easily causes fatigue and eye pain. As a general rule, a person should avoid looking at a computer screen or cell phone for a long time and rest for at least 5 to 10 minutes every 50 minutes by carefully blinking, looking away, or standing up. and moving. If the job requires a person to attach electronic displays for extended periods of time, then the person will have to wear blue light filter glasses. In addition, the commonly used blue-light glasses or sunglasses on the market all use conventional eyeglass lenses, and currently there is only one type of colored contact lens with filter functions of blue light and anti-UV. Accordingly, the main object of the present invention is to provide a colored contact lens, the lens having functions of filtering blue light and anti-UV (ultraviolet), and also to provide the colored contact lens with a color model.
[0002] To provide a better understanding of said objectives and the technological methods of the present invention, a brief description of the drawings is provided hereinafter, followed by a detailed description of the preferred embodiments.
[0003] Figure 1 shows a perspective view of the colored contact lenses of the present invention.
[0004] Figure 2 shows a schematic view of the first procedure for manufacturing colored contact lenses of the present invention. Figure 3 shows a schematic view of the second colored contact lens manufacturing procedure of the present invention. Figure 4 shows a schematic view of the third procedure for manufacturing colored contact lenses of the present invention. Referring to Fig. 1 which is a schematic view of a contact lens 10 of the present invention, in which the contact lens 10 is a three-layer processed device. An upper layer lens 11 is a flexible translucent structure (such as slightly tinted), a lower layer lens 13 is a flexible transparent structure, and an intermediate layer is a coloring agent 12. A dotted distribution of the coloring agent 12 above the intermediate layer forms rings of different depths. Consequently, the use of such a dotted distribution on the intermediate layer creates a beautiful natural effect for the wearer. The following is a general description of the contact lens manufacturing process: First procedure: reference is made to FIG. 2, in which a lower molded lens 20 is first placed on a first template 100. The top the lower molded lens 20 is provided with a circular recess 21, and a first printing pad 101 on a molding machine transfers the material of the lower layer lens 13 into the recess 21 of the lens After that, curing and shaping are carried out in a reaction tank.
[0005] Second procedure: reference is made to FIG. 3, in which the lower molded lens 20 containing the cured bottom layer lens 13 is placed on a second template 200. A second printing pad 201 of the molding machine applies the coloring agent 12 on the cured lower layer lens 13 to form a dotted annular distribution on the lower layer lens 13. The coloring agent 12 is dried by means of a reaction tank and fixedly positioned. Third Procedure: Reference is made to FIG. 4, in which the lower molded lens 20 containing the cured lower layer lens 13 treated with the coloring agent 12 is placed on a third template 300. Drops of the top layer lens 11 having a degree of correction and containing a UV light absorber (ultraviolet) and a blue light-filtering film-forming agent are dripped into the hardened lower layer lens 13, simultaneously covering the coloring agent 12. From further, an upper molded lens 30 is used to cover the lower molded lens 20. A circular protruding piece 31 on the underside of the upper molded lens 30 covers the interior of the recess 21 of the lower molded lens 20, simultaneously covering the upper part of the uncured and unshaped top layer lens 11. An adhesive distribution, an Then, a reaction and demoulding is performed on the unconverted contact lens assembly assembled from the above-mentioned top layer lens 11, coloring agent 12 and bottom layer lens 13 using a machine for producing spectacles, which is then washed by passing it through a hydration equipment to form the contact lens 10 as shown in FIG. 1. The UV absorber (ultraviolet filtering agent) ) in the upper layer lens 11 of the contact lens 10 is adapted to absorb light in the ultraviolet spectrum, and the blue light filter film forming agent has a blue light filtering efficiency. The aforementioned contact lens is a lens directly cast in a mold, an integral lens monomer mixture being placed in the mold and exposed to ultraviolet radiation and blue light to effect treatment and cure of the lens. polymer thereof. In conclusion, according to the above description of the embodiments, the present invention is certainly an innovative contact lens; which, in addition to being a colored contact lens having a degree of correction, is further provided with UV filtering and blue light functions.
[0006] It will be understood that the embodiments described herein are merely illustrative of the principles of the invention and that a wide variety of modifications can be made by those skilled in the art without departing from the spirit of the invention. and the scope of the invention as defined in the following claims.
