Description
本發明係有關於一種具抗藍光之隱形眼鏡加工製法，尤指一種可簡化製程並一貫化生產具抗藍光及抗紫外線之抗藍光隱形眼鏡製法。 The invention relates to a method for processing contact lens with anti-blue light, in particular to a method for simplifying the process and consistently producing anti-blue light and anti-ultraviolet anti-blue contact lens.
按，科技發展日新月異，尤其電子產品如LED燈、平板電腦、電視、智慧型手機等3C產品都會釋放出藍光，因使用3C產品時，眼睛會直視螢幕所發出的藍光，藍光是可見光中最靠近紫外線光波之能量較強的部分，波長介於380nm~530nm之間，其波長較短會提前在視網膜前聚焦，容易造成散射，因此眼睛需更用力聚焦而無法放鬆，長時間容易導致眼睛視物影像對比及清晰度降低而增加眼睛疲勞。且其藍光射入眼睛時不會被角膜和水晶體吸收，可穿透角膜與水晶體直射入黃斑部，若吸收過多藍光，初期會產生眼睛刺痛、畏光等症狀，長期將使黃斑部發炎、水腫，可能會在黃斑部中央形成隱結，一旦隱結破裂導致出血，將造成中央視力缺損，無法正眼看清楚事物，因此過去好發於老年人的黃斑部病變隨著現代生活的改變以及長時間面對藍光的刺激，年齡層有往下降的趨勢，抗藍光已經成為重要之課題。對此，中華民國專利第M487455號揭露了一種「具有濾藍光及抗UV功能之彩色隱形眼鏡」，請參閱第一圖，其包含一由上、 中間及下層鏡片所組成之包覆型隱形眼鏡10，該上層鏡片11為軟質半透明狀且該下層鏡片13為軟質透明狀，中間層鏡片為該著色劑12，其中該著色劑12係固化在該下層鏡片13上，而該上層鏡片11包含有紫外光吸收劑及濾藍光鍍膜劑者。 According to the rapid development of technology, especially 3C products such as LED lights, tablet PCs, TVs, smart phones, etc. will release blue light. When using 3C products, the eyes will look directly at the blue light emitted by the screen. Blu-ray is the closest in visible light. The energy of the ultraviolet light wave is stronger, the wavelength is between 380nm and 530nm, and the shorter wavelength will be focused in front of the retina in advance, which is easy to cause scattering. Therefore, the eye needs to focus more hardly and can not relax, and it is easy to cause eye vision for a long time. Increased image contrast and reduced clarity increase eye fatigue. And when the blue light is injected into the eye, it will not be absorbed by the cornea and the crystal. It can penetrate the cornea and the crystal directly into the macula. If it absorbs too much blue light, it will cause eye irritation and photophobia in the early stage, which will cause inflammation of the macula in the long term. Edema may form a hidden knot in the center of the macula. Once the occlusion and rupture lead to bleeding, it will cause central vision defects, and it is impossible to see things clearly. Therefore, the macular lesions that occurred in the elderly in the past have changed with modern life and Time is facing the trend of blue light, and the age layer has a tendency to decline. Anti-blue light has become an important issue. In this regard, the Republic of China Patent No. M487455 discloses a "color contact lens with blue light filtering and anti-UV function", please refer to the first figure, which includes a The coated contact lens 10 composed of the middle and lower lenses, the upper lens 11 is soft translucent and the lower lens 13 is soft transparent, and the intermediate lens is the coloring agent 12, wherein the coloring agent 12 is cured in The lower layer lens 13 includes an ultraviolet light absorber and a blue light filter.

The scope of safety permission will have the effect of hurting the eyes, and the contact lens 10 is mainly composed of upper, middle and lower lenses.

Inside, after the silicone head 26 is moved upward, the mother mold is The color ink 280 of the pattern 28 is left in the optical mold 25, and the monomer 24 after the first preparation 23 is prepared in the optical mold 25 of the master mold, the color in the optical mold 25 of the master mold The ink 280 can be transferred onto the monomer 24 by die casting or spin molding, and then subjected to the UV light curing step 21 and the extraction step 22 to form an anti-blue light or blue light resistant A colored contact lens that resists UV rays and does not produce color shift.
綜合以上所述，請繼續參閱第二圖所示，藉由本發明包含該光學模製備步驟20與該萃取步驟22，該光學模製備步驟20採用旋模法與模鑄法，俾使搭配該UV光固化步驟21時，可實現生產出同時具有抗藍光及抗紫外線之隱形眼鏡，且同時可使抗藍光及抗紫外線之隱形眼鏡納入彩色隱形眼鏡之一貫化製造，進而使本發明可達到簡化製程並一貫化生產具抗藍光及抗紫外線隱形眼鏡之功效。 In summary, please refer to the second figure. The present invention includes the optical mold preparation step 20 and the extraction step 22. The optical mold preparation step 20 is performed by a spin molding method and a die casting method. In the photocuring step 21, it is possible to produce a contact lens which has both anti-blue light and ultraviolet resistance, and at the same time, the blue- and ultraviolet-resistant contact lens can be incorporated into the color contact lens, and the invention can be simplified. And consistently produce the effect of anti-blue light and anti-UV contact lenses.
