隱形眼鏡系統進一步包含一用於使一隱形眼鏡系統戴鏡者 之眼球之眼臉裂隙之間的視景偵測器穩定的構件。 本發明亦揭露一種用於製作電致動隱形眼鏡系統之方 法。該方法包含封裝一電致動元件並使所封裝之電致動元 件和一電源附著至一隱形眼鏡。 本發明之觀點將引用其實例性具體實施例如附圖所示予 以詳細說明。 【實施方式】 87195 200408850 根據本發明之某些具體實施例，揭露一種電致動隱形眼 鏡系統。隱形眼鏡系統包含一隱形眼鏡、一附著至該隱形 眼鏡之電致動元件、一附著至隱形眼鏡並與該電致動元件 作電子通訊之視景偵測器、以及一附著至隱形眼鏡以提供 電力予電致動元件和視景偵測器之電源。電致動元件至少 提供一用於視力矯正之焦距。 電致動元件可包含一或多個電致動材料層，如高分子凝 膠及/或液晶，在藉由所施加之電壓予以致動時，產生可隨 著她加至該電致動材料之電壓而變之折射係數。在一戴鏡 者看透隱形眼鏡系統中含有電致動元件之區域時，折射係 數提供電致動视力矯正予該戴鏡者。隱形眼鏡系統可提供 視力权正區，孫視力校正區包含一用於固定距離視力校正 之區域及用於電致動視力校正之區域。 在某些具體實施例中，該一或多個電致動元件之電致動 層中的每一層皆包含一具有複數個奇特之網栅元件之網栅 陣列，其中每—個網柵元件皆能夠單獨作用。每—個網拇 凡件皆可連接至複數個實f透明之電極且係藉由例如二氧

<類I光透明導電材料的導電層可予以附著至金屬層。該 導電層接著可予以附著至一電源以將一所施加之電壓導至 金屬層中之複數個電極。 適當的電致動材料包含各類液晶和高分子凝膠。這些種 類包含向列型、層列型、和膽固醇型液晶、高分子液晶、 π分子散列型（p〇lymer dispersed)液晶以及光電聚合物 (electro-optic polymer) 〇 若將例如向列型液晶之類的液晶當作電致動材料，則一 對準層因向列型及許多其它種液晶具有雙折射而有具有必 要性。也;f尤疋說，該等液晶在未施加電壓且曝露於未經極 化之光時顯示兩種不同之焦距。雙折射在視網膜上造成雙 W或模糊影像。為了減輕雙折射，可使用一與該第一電致 動材料層呈垂直之第二電致動材料層。依此方式，光之兩 種極化係由該兩層予以平均地聚焦，且所有光係聚焦於相 同之焦距。 或者’對具有大對掌性成分之膽固醇型液晶之使用可作 為較佳之電致動材料。與向列型和其它一般液晶不同，膽 87195 200408850 固醇型液晶不具有向列型液晶之極性，免除了對單一電致 動層中多層電致動材料之需要。 各種可用在本發明具體實施例之電致動元件之電致動層 係說明於2003年4月25日所收錄標題為“電致動多聚焦眼鏡 和叙片（Electro-Active Multi-Focal Spectacles and Lens)”

鏡者之遠距視力中非傳統折射誤差之電致動校正。該校正 可提供比20/20還好之視力予戴鏡者。 在需要多焦距的情況下，一視景偵測器可用於自動判斷 戴鏡者正在看的地方以及從而電致動元件應如何予以致 動’用以提供適當之焦距或基於戴鏡者之注視之焦距。親 景偵測器這種裝置是用來偵測戴鏡者所需之焦距變化並取 決於隱形眼鏡系統戴鏡者所需乏痛木 而义適當視力矯正而調整施如 於電致動元件之電壓以切換隹距。、目！ μ

一與控制器之記憶體内所儲存之視力處方一致之新折射係 數。孩新折射係數在隱形眼鏡系統中產生一適當的光度而 與焦距變化相符合。 在另一實例性具體實施例中，視景偵測器可為隱形眼鏡 系統中微小之微迴轉儀或微加速度計。眼球或頭部之小而 快之抖動或扭轉會觸動該微迴轉儀或微加速度計並使—切 換器經由預先決定之位置設定迴轉、將電致動元件之聚焦 87195 -10- 200408850 變為期望之校正。例

戴鏡者向下和向内旋轉之旋轉動作。眼球位置代表眼球正 在謂取且微迴轉儀從而對近距視力改變電致動元件之聚 焦0 任何隱形眼鏡之移動及/或旋轉皆在正常使用期間發生， 如戴鏡者吃眼的時候。移動及/或旋轉會藉由電致動隱形眼 鏡系統中視景㈣器之重量予以增強。以，隱形眼鏡系 統會穩定而使視景偵測器之位置維持在一抗拒移動之固定 位置。在彳貞測器為測距儀的具體實施例中，測距儀在眼險 87195 -11 - 200408850 裂隙之間係穩定的，並且防止隱形眼鏡系統之移動及/或旋 轉。眼險之裂隙，或開口，係眼球在眨眼之間曝露最多的 部分。使測距儀維持在眼瞼裂隙之間能夠讓大部分光不間 斷地流向測距儀。對測距儀作隱藏，如同測距儀在眼險後 方旋轉，會導致測距儀之傳送由眼瞼反射而非所觀視之物 件。14會使測距儀無法對正確之焦距致動適當地判斷物件 距離且隱形眼鏡係統無法適當地作用。 在視景偵測器含有一微迴轉儀或傾斜切換器之具體實施 例中，鏡片之旋轉改變視景偵測器的方向。在這種情況下， Μ迴轉儀或傾斜切換器會在眼球上旋轉，使得當戴鏡者向 上看時，裝置會定向而錯誤地偵測到戴鏡者是向下看，致 動不適當的焦距。 在一本發明之具體實施例中，如圖i所示，電致動隱形眼 鏡系統100具有一附著至一隱形眼鏡12〇之電致動元件U0。 孩隱形眼鏡120可選擇性地具有一毗連隱形眼鏡12〇外圍之 舒適錐狀物（C0mf0rt taper)16〇。該舒適錐狀物16〇在戴鏡時 會降低眼球或眼瞼對電致動隱形眼鏡系統1 〇〇之敏感度。 一如說明所述可與一控制器整合之測距儀丨3()係置於或靠 近隱形眼鏡系統100之水平頂點，所以測距儀i3〇在戴上隱 形眼鏡系統100時係處於眼瞼裂隙之間，而測距儀13〇平常 係位在相較於水平頂點大約加或減四十五度之間。測距儀 1 3 0最好是位在相較於水平頂點大約加或減十五度之内，且 更好的疋位在相較於水平頂點大约加或減十度之内。測距 儀1 3 0可以距隱形眼鏡系統丨〇〇中心之任一輻射位置而置。 87195 -12 - 200408850 在某些具體實施例中，測距儀130係置於隱形眼鏡系統ι〇〇 之視力矯正區的外側而儘可能少地干擾戴鏡者之視力。 一旦測距儀130置於隱形眼鏡120之表面上或主體中之期 主仅置，fe形眼鏡系統1 00會穩定而避免隱形眼鏡系統1⑻ 之移動及/或旋轉並在戴上隱形眼鏡系統100時使測距儀 維持在眼瞼裂隙之間。隱形眼鏡系統1〇〇可經由在隱形眼鏡 120之上或之中放置複數個穩定片14〇、ι45而使其穩定。在 某些實例性具體實施例中，這些穩定片14〇、1C可為棱鏡 加重物（prism weight)、加厚物（siab-0ff)、或兩者之結合。 穩足片140、145在將隱形眼鏡系統1〇〇戴上眼球時維持隱形 眼鏡系統100之方向，實質避免隱形眼鏡系統1〇〇旋轉，隱 形眼鏡系統之旋轉會使測距儀130旋轉至眼瞼後方之隱蔽位 置。 ^ 稜鏡加重物之厚度通常隨著離隱形眼鏡中心之輻射距離 之增加而增加δ棱鏡加重物之較厚部分接觸下方眼瞼並藉 由在隱形眼鏡120之基部產生遞增之質量集中度 (concentration)以穩定鏡片旋轉。或者，加厚技術包含隨著 離隱形眼鏡中心之輻射距離之增加而遞減之厚度同時修改 隱形眼鏡之外部和内部表面，致使上和下眼瞼朝眼球表面 以相反方向擠壓隱形眼鏡。 應鑑知穩定片140、145可呈任一適用於穩定隱形眼鏡系 統1 0 0而不實質干擾戴鏡者視力之形狀和尺寸。例如，雖然 每一個圖1所示之穩定片140、1 45皆圖示為單一、弦月狀物 片，隱形眼鏡系統100仍可藉由一串由許多經配置用以產生 87195 -13- 200408850 類似穩定效應之較小穩定片予以穩定。依此方式，應進一 步鍾知使用一或多個穩定片以穩定隱形眼鏡系統1 〇〇之任一 組a數目皆可合併在本發明之各種具體實施例中。 如圖1所示’隱形眼鏡系統1 ο 〇包含一用於鱗正遠距視力 <固疋式遠距光區150。藉由看透隱形眼鏡系統ι〇〇在固定 式运距光區1 5 0中之區域而提供之遠距視力校正是在電致動 元件11 0對其它遠距視力之焦距所提供之電致動視力校正之 外額外具有的。這些區域共同組成隱形眼鏡系統1 〇〇所提供 之總視力校正區。在電致動元件1丨〇因各種理由而失效的情 況下’例如電力喪失導致所施加之電壓停止流經電致動元 件’固足式遠距光區丨50使戴鏡者繼續對遠距視力作視力矯 正。維持遠距视力是有重要性的，因為喪失所有視力矯正 可能會造成危險，舉例如電致動元件1丨〇在戴鏡者駕駛時失 效的狀況。 隱形眼鏡120可包含一光學儀器部分和一非光學儀器部分 其中（一或兩者皆包含。若隱形眼鏡12〇含有一光學儀器部 分’則該光學儀器部分包含隱形眼鏡系統1 〇〇之固定式遠距 光區150。隱形眼鏡12〇之非光學儀器部分對隱形眼鏡系統 100提供機械支承，且可包含一或多個穩定片14〇、ι45。然 而’應鑑知在某些具體實施例中，整個隱形眼鏡12〇雖然在 這些具體實施例中可具有一固定式光源，仍可在隱形眼鏡 12 0覆盍瞳孔之區域外側提供視力矯正。 隱形眼鏡1 20由圖！所示之前視圖係呈實質圓形且具有一 適用於匹配眼球曲率之凹側。隱形眼鏡1 2〇之尺寸可取決於 87195 -14- 200408850 戴鏡者要配合隱形眼鏡系統100之某些物理屬性作變化，舉 例如戴鏡者之眼球尺寸或曲率或者戴鏡者之年齡。一般而 吕，隱形眼鏡系統100之總視力矯正區係呈實質圓形且直徑 大約為米至10釐米，最好約為5釐米至8楚米。 電力可藉由對隱形眼鏡系統i 00附上舉例如電池、電容、 或其它電力儲存裝置之類的同形電源（c〇nf〇rmal s〇urCe)190而提供予電致動元件11〇、以及測距儀13〇和控制 器。該同形電源190係一作成隱形眼鏡120形狀之薄膜。電 源1 90之形狀可呈環狀並附加於視力矯正區外側之隱形眼鏡 120，這可遍及隱形眼鏡12〇均勻地分佈電源重量而不致干 擾戴鏡者之視力。在某些具體實施例中應鑑知電源19〇的形 狀可呈環狀，但卻有如穩定片145 一般地附加至隱形眼鏡 120。在這些具體實施例中，電源19〇之重量可作用為反平 衡以進一步穩定隱形眼鏡系統i 〇〇並維持眼瞼裂隙之間的測 距儀130。 電源1 90可提供如電池一般已事先儲存予以之電力。或 者，電源190可使用電子機械轉換技術將動能從眼球之移動 轉換成電能。 電致動元件11 0對至少一個焦距提供電致動視力矯正。這 可包含近距及/或中距視力，其中近距及/或中距視力對多焦 距需要視力矯正之戴鏡者係最常所需之焦距。另外，中距 視力可為近中距視力和遠中距視力其中之一或兩者皆具。 在這些具體實施例中，除了藉由僅致動電致動元件之某些 部分使用適應性光學儀器電致動矯正戴鏡者遠距視力之非 87195 -15- 200408850 傳統折射誤差之外，遠距視力係由隱形眼鏡12〇予以提供。 消除非傳統折射誤差可將戴鏡者之視力矯正至優於， 南達並含括將戴鏡者視力矯正為優於2〇/1〇。 隱形眼鏡系統100中由電致動元件110對視力矯正所提供 之區域可與固定式遠距光區150所提供之視力矯正區大小一 樣或還要小。在電致動元件110之區域比固定式遠距光區150 還小之至少一個具體實施例中，電致動元件丨10覆蓋至少一 邵分瞳孔，且最好是在瞳孔的中央。 在本發明之某些具體實施例中，電致動元件丨10是在附著 至隱形眼鏡120之前予以封裝的。一經過封裝之元件i 1〇之 實施例係如圖2所示，圖2為圖i所示之隱形眼鏡系統1⑻之 剖面圖。一囊膜（capsule)U5含有電致動元件11〇。隱形眼 鏡120可繞著該囊膜115予以鑄模，使得囊膜115置於隱形眼 鏡120之主體内。囊膜115係呈實質圓形且係適用於容納電 致動元件110。囊膜115對光呈光學透明且戴鏡者得以透過 囊膜115觀視。 囊膜11 5最好呈硬質且可由非透氣、斥水性材料或透氣材 料予以架構。一合適之非透氣、斥水性材料包含聚甲基丙 婦酸甲酯（俗稱壓克力，PMMA)。 適用且硬質之透氣材料舉例包含與丙烯酸矽氧烷（silic〇ne acrylate)作異分子聚合之甲基丙烯酸甲酯（MMA)、或與 methacryloxypropyl tds(三羥基甲基甲胺ktris)作異分子聚 合之MMA。MMA-TRIS是一種對囊膜115尤其適用之透氣材 料0 87195 -16- 200408850 隱形眼鏡1 20可由硬質之透氣材料或彈性親水性材料予以 構成。適用之彈性親水性材料之實施'例舉例包含甲基丙缔 酸羥乙酯（hydroxyethyl methacrylate)(HEMA)之類的熱固性 (thermo-set)高分子水凝膠（polymer hydrogel)，與二甲其丙 烯酸酯（ethylene dimethacrylate)(EDMA)或乙-辟 monogethacrylate(EGDMA)其中之一交叉結合之 hema、戈 者如咼分子乙燒石夕氧燒（p〇lydimethylsiloxane)(PDMS)之類 以矽氧烷為基礎的聚合物。 光學等級親水性、透氣性和非透氣性材料再加上那些所 这材料在1¾形眼鏡技藝中是廣為人知的。一般而言，這此 材料中的任何一種材料對於囊膜115或隱形眼鏡12〇之構成 皆可作任意組合予以使用。然而，最好為一種硬質、親水 性及/或防水囊膜與一硬質透氣隱形眼鏡或彈性親水性隱形 眼鏡中任一種的組合。 在某些具體實施例中，測距儀13()以及控制器和電源可與 電致動元件110 —起密封在囊膜115内，使得隱形眼鏡系統 1〇〇《所有電子元件皆包含在囊膜115内。可具有之優點在 於製造成本因電子元件可分離製造和封裝而降低。另外， 囊腱115可由斥水性或防水材料予以構成、或可用各種防水 之密封劑予以密封，可提供之優點在錢電子元件免於受 到眼球〈眼淚或其它分泌物所影響。若分離構成，則可在 稍後才將囊膜！ i 5附著至隱形眼鏡i 2()以產生隱形眼鏡系統 1〇〇而不需分別地將測距儀13〇附著至隱形眼鏡η。。然而， 應鑑知囊膜115内測距儀13〇之放置是不需要的且可放在囊 87195 -17- 200408850 膜115外侧之上或之中的何意位置。在此種情況下，測距儀 130係經由從囊膜II5通入隱形眼鏡而至測距儀13〇之導 體予以連接至電致動元件丨丨〇。 在某些具體實施例中，如圖3所示，會希望僅使用舉例如 單一加厚物或稜鏡加重物之單一穩定片345以穩定隱形眼鏡 系統300。該單一穩定片345中至少有一部分通常係附著在 隱形眼鏡320之水平頂點底下。如圖3所示，隱形眼鏡系統3〇〇 中藉由包含額外之穩定片而潛在模糊之區域係減少的。因 此’隱形眼鏡系統300之較大區域可用於提供光源作視力橋 正。額外之鏡片區域用以提供視力矯正之可用性在舉例如 夜視（night vision)或其它低光設定（i〇w Ught setting)之應用 中尤具優點。在弱光（decreased light)的情況下，曈孔擴張 會使瞳孔擴大到隱形眼鏡系統300之小視力矯正區的外側， 造成視覺模糊不清或失真的可能性。 在又一實例性具體實施例中，如圖4a所示，隱形眼鏡系 統400是在不使用附著至隱形眼鏡420之穩定片的情況下以 替代方式予以穩定。隱形眼鏡系統400反而是藉由經過截短 之隱形眼鏡420予以穩定。穩形眼鏡420是在大約5度的範圍 内沿著低於且實質平行於隱形眼鏡420水平頂點之弦部 (chord)470予以截短。隱形眼鏡420藉以截短所沿靠之弦部 470通常是位在含有電致動元件4 1 0之囊膜的外侧。隱形眼 鏡420藉以截短所沿靠之弦部470在穿戴隱形眼鏡系統400時 不碰觸隱形眼鏡系統4〇〇中覆蓋瞳孔並提供視力矯正予戴鏡 者之任何部分。隱形眼鏡420通常可截短大約百分之五至十 87195 -18- 200408850 五以穩定隱形眼鏡系統400，僅管隱形眼鏡420有更多或更 少的邵分可基於戴鏡者之特定視力需求而作截短。 隱形眼鏡420之截短本身可足以穩定隱形眼鏡系統4〇〇並 在穿戴隱形眼鏡系統4〇〇時在眼瞼裂隙之間維持測距儀 430。或者，一或多個如加厚物或稜鏡加重物之類的穩定片 445可與經過截短之隱形眼鏡42〇結合使用，如圖4b所示， 用以進一步穩定隱形眼鏡系統4 〇 〇。在此具體實施例中，截 短最好為最小以使得加厚物或棱鏡加重物可附著至隱形眼 鏡420而致使與隱形眼鏡系統4〇〇中提供視力矯正之區域重 疊。 在某些具體實施例中，例如一電致動隱形眼鏡系統戴鏡 者之視力僑正額外需要散光矯光的情況下，隱形眼鏡系統 亦可包含一散度（toric power)，如圖4a之進一步描繪所示。 在這些具體實施例中，隱形眼鏡系統4〇〇係經穩定以維持隱 形眼鏡420散軸（toric axis)480之方向並維持測距儀430之位 置。散軸480最好是在將測距儀430置於隱形眼鏡420上之前 予以設定，如隱形眼鏡420之初始製造期間。或者，測距儀 430首先可置於隱形眼鏡420上並加以穩定，接著相對於測 距儀430之方向使散軸480定向。 在某些具體實施例中，隱形眼鏡產生少量或未產生散度， 且隱形眼鏡系統之固定式遠距光區所提供之遠距視力矯正 卻可由内含電致動元件之囊膜予以提供。囊膜可經製造及 表面化而對遠距視力矯正直接提供一光度。如圖5所示，隱 形眼鏡為一由親水性材料所構成之裙擺（skirt)525，形成一 87195 -19- 200408850 圍繞囊膜550之環狀物，這有助淚流並且降低對囊膜550之 眼臉敏感度。隱形眼鏡裙擺525僅於囊膜之外圍527附著至 囊膜550。 囊膜550具有一經過表面化以產生一與戴鏡者對遠距視力 矯正之處方匹配之折射率的曲率半徑。圖5之具體實施例中 有一個未置於隱形眼鏡主體内而由一隱形眼鏡裙擺5 2 5予以 圍繞之囊膜550。隱形眼鏡系統5〇〇可藉由加厚、棱鏡加重、 及/或別處所述相同方式中之截短予以穩定。 在又一具體實施例中，隱形眼鏡系統之固定式遠距光度 可由隱形眼鏡和囊膜之組合予以提供。例如，囊膜可經表 面化而具有一折射率並可置於亦具有一折射率之隱形眼鏡 之主體中。同時，折射率可為附加的，以提供一固定式遠 距光度來矯正戴鏡者之遠距視力。 應鑑知，附了已在本文之實例性具體實施例中予以說明 各種其它方法亦可用在穩 此’這些方法在應用於本 之棱鏡加重、加厚及截短之外，各濟 定多聚焦和散光隱形眼鏡中。因此， 文所述之具體實施例時已在本發明之範_内加以考慮200408850 (1) Description of the invention: [Technical field to which the invention belongs] The present invention relates to the field of optics.

A detector, and a power source attached to the contact lens to provide power to the electrically actuated element and the vision detector. The electrically actuated element provides at least a focal distance for vision correction. The electrically actuated element may include one or more An electrically actuated material layer, such as a polymer gel and / or liquid crystal, when actuated by an applied voltage, produces a refractive index that can change with the voltage applied to the electrically actuated material. When a wearer sees through the area of the contact lens system that contains the electro-actuated elements, the refractive index provides electro-actuated vision correction to the wearer. The contact lens system can provide vision Right area, Sun vision correction area includes an area for fixed distance vision correction and an area for electrically actuated vision correction. In some embodiments, the one or more electrically actuated elements are electrically actuated. Each layer in the layer includes a grid array with a plurality of peculiar grid elements, each of which can function independently. Each of the mesh elements can be connected to a plurality of real f transparent elements. The electrodes are separated from the adjacent grids by, for example, a transparent insulating material, such as the one given by Dioxin. Small by changing the electrically actuated materials applied to the different grid elements of the array: Fine adjustments are performed in the electrically actuated elements to correct visual aberrations and / or more orthodox or non-traditional refraction errors, such as coma and spherical aberrations, and also correct other aberrations, such as chromatic aberration.) . H ㈣ϋ '' farsightedness, presbyopia 1 and the traditional distortion of the stigma class < outside of the frame, there are still non-traditional refraction errors correction, of which the traditional 87195 ζυυ4υ »8 ^ υ correction of refraction errors can also be electrically actuated Tt pieces An electrically actuated layer is provided. Or, the actuating layer contains a net thumb array composed of a strange grid grid element, and a handle, A / t mountain /, in the case of an electric actuating layer, further includes a metal layer pair + Layer, a conductive layer, and / or an insulating layer. The metal layer may be etched to include a private electrode array separated by a layer of insulating material located on the metal layer. The electro-active material can be attached to the side of the metal that has the electrical array. On the other side of the metal layer, a conductive layer, which may include, for example, an indium tin oxide < Class I light transparent conductive material, may be attached to the metal layer. The conductive layer can then be attached to a power source to conduct an applied voltage to a plurality of electrodes in the metal layer. Suitable electrically actuated materials include various types of liquid crystals and polymer gels. These categories include nematic, smectic, and cholesteric liquid crystals, polymer liquid crystals, π molecularly dispersed liquid crystals, and electro-optic polymers. If, for example, nematic liquid crystals Liquid crystals such as these are used as electrically actuated materials, and an alignment layer is necessary because nematic and many other types of liquid crystals have birefringence. Also, fyou said that these liquid crystals show two different focal lengths when no voltage is applied and exposed to unpolarized light. Birefringence creates a double W or blurred image on the retina. To reduce the birefringence, a second electro-actuated material layer may be used that is perpendicular to the first electro-actuated material layer. In this way, the two polarizations of light are evenly focused by the two layers, and all light systems are focused at the same focal length. Alternatively, the use of a cholesteric liquid crystal having a large palmar component can be used as a better electro-actuating material. Unlike nematic liquid crystals and other general liquid crystals, bile 87195 200408850 sterol liquid crystals do not have the polarity of nematic liquid crystals, eliminating the need for multiple electro-actuated materials in a single electro-actuated layer. The description of the electro-actuated layers of various electro-actuated elements that can be used in specific embodiments of the present invention is included on April 25, 2003 and titled "Electro-Active Multi-Focal Spectacles and Lens) "in the Republic of China Patent Application No. 092 109720, which is incorporated herein by reference in its entirety. Contact lens systems can be focused to provide vision correction for more than one focal length. In some embodiments of the present invention, vision correction for distance vision is provided by a fixed optical instrument. For distance vision, for example, near vision or intermediate vision, the focal length of the vision bridge is provided electrically actuated. In addition, even in specific embodiments in which long-distance vision is provided by a fixed optical instrument, the contact lens system can provide an electrically actuated correction of non-traditional refraction errors in the distance vision of the wearer. This correction provides better vision to the wearer than 20/20. In situations where multiple focal lengths are required, a vision detector can be used to automatically determine where the wearer is looking and thus how the electrical actuation element should be actuated 'to provide the appropriate focal length or based on the wearer's gaze Focal length. This device is used to detect the change in the focal length required by the wearer of the lens and depends on the pain of the contact lens system. The appropriate vision correction is adjusted and applied to the electrically actuated components. Voltage to switch the pitch. Eye! μ narrow ..., distance. The vision detector can be a birthday finder or an eye-tracking system, such as a micro, rotary or tilt switch, or the vision detector can be one or more instrument systems Of combination. If the vision detector is a rangefinder, the rangefinder can use a variety of wave sources, 87195 -9- 200408850, such as lasers, f-light diodes, radio frequency waves, microwaves, or ultrasonic pulses. The object viewed from the foot position is based on the transmission time from the transmission of the rangefinder to the reflection of the observation object received by the rangefinder based on the distance from the object to the wearer. The rangefinder can include a transmitter and a detector connected to the controller. In another embodiment, a single device can be manufactured to operate in dual mode 'as if both the transmitter and the detector were connected to the controller. The controller may be a processor, a microprocessor, an integrated circuit, or a chip containing at least one memory element. The controller stores information such as a prescription for vision (Vi — prescription), where the vision department contains many prescriptions for lens wearers with different focal lengths. The device can be a component or integrated with the rangefinder ... In some specific embodiments, the transmitter of the rangefinder is an organic light emitting diode (0LED) that can be translucent or transparent, resulting in Minimal interference with the vision of the wearer. The rangefinder communicates electronically with the electrically actuated components either directly or via a controller. When the rangefinder detects that the focal length generated by the electrically actuated element should be switched to provide a different focal length, the rangefinder will notify the controller electronically. The controller responds to the signal and adjusts the voltage applied to the electrically actuated element to produce a new refractive index consistent with the vision prescription stored in the controller's memory. The new refractive index produces a suitable luminosity in a contact lens system in accordance with a change in focal length. In another exemplary embodiment, the vision detector may be a tiny microgyrometer or a micro-accelerometer in a contact lens system. A small and fast jitter or twist of the eyeball or head will touch the microgyrometer or microaccelerometer and cause the switch to rotate through a predetermined position setting, turning the focus of the electrical actuating element 87195 -10- 200408850 into the desired Of correction. For example, when the micro-accelerometer detects movement ° '= with a rangefinder using a microgyrometer or "", the controller will provide power to the π rangefinder in accordance with the program, resulting in a rigid view of the view. Questions will be asked by the rangefinder to determine if vision correction is needed or not. Preferably, the rangefinder is turned off after a predetermined time or period of time before the eyeball moves. In another exemplary embodiment, another vision detector, = :::: Broken Mirrorist's ™. "Tilt down or up, which means someone is facing straight into the distance. 刖 < List as' A tilt switch of a descriptive nature may include a dead switch installed in the controller, which is only worn when wearing glasses Or close at a predetermined angle that is off-level—providing power to the rangefinder and / or the controller ’s circuitry. In addition, contact lens systems use additional and seek for an object system Sensing at a predetermined time period within a short or medium distance before the switch occurs. It should be known that the microgyro and / or tilt switch can be used as a vision detector independent of the rangefinder. For example, ' The microgyroscope can detect the rotation of the wearer's eyeball in relation to the downward and inward rotation of the wearer's eyeball. The position of the eyeball represents that the eyeball is being taken and the microgyroscope changes the focus of the electric actuating element for close vision The movement and / or rotation of the contact lens occurs during normal use, such as when the wearer eats his eyes. The movement and / or rotation can be enhanced by electrically actuating the weight of the vision device in the contact lens system. The eyewear system is stable and maintains the position of the vision detector in a fixed position that resists movement. In the specific embodiment where the rangefinder is a rangefinder, the rangefinder is in the position of the eye danger 87195 -11-200408850 The system is stable, and prevents the movement and / or rotation of the contact lens system. The crevice, or opening, is the most exposed part of the eyeball in the blink of an eye. Maintaining the rangefinder between the eyelid gaps allows most of the Light flows uninterrupted to the rangefinder. Hiding the rangefinder, as if the rangefinder rotates behind the eye, will cause the rangefinder's transmission to be reflected by the eyelid rather than the object being viewed. 14 Will make the rangefinder The correct focus distance cannot be used to properly determine the object distance and the contact lens system cannot function properly. In specific embodiments where the vision detector includes a microgyrometer or tilt switch, the rotation of the lens changes the vision detection In this case, the M gyroscope or tilt switch will rotate on the eyeball, so that when the wearer looks up, the device will orient and incorrectly detect that the wearer is looking down, causingImproper focal length. In a specific embodiment of the present invention, as shown in FIG. I, the electrically actuated contact lens system 100 has an electrically actuated element U0 attached to a contact lens 120. The contact lens 120 is optional It has a comfortable cone (C0mf0rt taper) 16 adjacent to the periphery of the contact lens 120. The comfortable cone 16 will reduce the sensitivity of the eyeball or eyelid to the electrically actuated contact lens system 100 when wearing the lens. As described, the rangefinder that can be integrated with a controller 3 () is placed on or near the horizontal vertex of the contact lens system 100, so the rangefinder i3〇 is in the position when the contact lens system 100 is put on. Eyelid fissures, and the rangefinder 13 is usually located at approximately plus or minus forty-five degrees compared to the horizontal apex. The rangefinder 1 30 is preferably located at approximately plus or minus the horizontal apex. Less than fifteen degrees, and better niches within plus or minus ten degrees compared to the horizontal apex. The distance measuring device 130 can be placed at any radiation position in the center of the contact lens system. 87195 -12-200408850 In some embodiments, the rangefinder 130 is placed outside the vision correction area of the contact lens system ι〇 to minimize the vision of the wearer. Once the rangefinder 130 is placed on the surface of the contact lens 120 or in the main body, the fe lens system 100 will stabilize and avoid the movement and / or rotation of the contact lens system 1 系统 and wear the contact lens system 100. Keep the rangefinder between the eyelid cracks from time to time. The contact lens system 100 can be stabilized by placing a plurality of stabilizers 14 and 45 on or in the contact lens 120. In some exemplary embodiments, these stabilizers 14 and 1C may be prism weights, siab-0ffs, or a combination of both. The foot stabilizers 140 and 145 maintain the orientation of the contact lens system 100 when the contact lens system 100 is put on the eyeball, substantially avoiding the rotation of the contact lens system 100, and the rotation of the contact lens system will cause the rangefinder 130 to rotate to the eyelid. A hidden position behind. ^ 厚度 The thickness of the weight usually increases with the increase in the distance from the center of the contact lens. The thicker part of the δ prism weight contacts the lower eyelid and produces an increasing mass concentration at the base of the contact lens 120. To stabilize the lens rotation. Alternatively, the thickening technique involves simultaneously modifying the external and internal surfaces of the contact lens with decreasing thickness as the radiation distance from the center of the contact lens increases, causing the upper and lower eyelids to squeeze the contact lens in opposite directions toward the eyeball surface. It should be known that the stabilizers 140, 145 may have any shape and size suitable for stabilizing the contact lens system 100 without substantially interfering with the vision of the wearer. For example, although each of the stabilizing plates 140, 145 shown in FIG. 1 is shown as a single, meniscus plate, the contact lens system 100 can still be used to generate 87195 -13-200408850 by a series of Smaller stabilizers similar to the stabilizing effect stabilize. In this way, it should be further known that the use of one or more stabilizers to stabilize any number a of the contact lens system 1000 can be incorporated in various embodiments of the present invention. As shown in FIG. 1, the 'contact lens system 1' includes a fixed-type long-range light zone 150 for positive long-distance vision. The long-distance vision correction provided by looking through the area of the contact lens system ιOO in the fixed distance light zone 150 is the electric actuation provided by the electric actuating element 11 0 for the focal distance of other long-distance vision In addition to vision correction. These areas together constitute the total vision correction area provided by the contact lens system 1000. In the event that the electric actuating element 1 fails for various reasons, 'for example, the loss of power causes the applied voltage to stop flowing through the electric actuating element', a fixed-type remote light zone 50 allows the wearer to continue to Vision for vision correction. Maintaining long-distance vision is important because losing all vision corrections can be dangerous, such as a situation where the electrically actuated element 1 fails when the lens wearer is driving. The contact lens 120 may include an optical device portion and a non-optical device portion (one or both of which are included. If the contact lens 120 includes an optical device portion, then the optical device portion includes a fixed type of a contact lens system 100 Telephoto zone 150. The non-optical instrument portion of the contact lens 120 provides mechanical support to the contact lens system 100, and may include one or more stabilizers 14 and 45. However, it should be recognized in certain embodiments Although the entire contact lens 120 can have a fixed light source in these specific embodiments, vision correction can still be provided outside the area where the contact lens 120 covers the pupil. The contact lens 120 is shown in the previous view by the picture! It is substantially round and has a concave side suitable for matching the curvature of the eyeball. The size of the contact lens 120 may depend on 87195 -14- 200408850. The wearer of the lens must adapt to certain physical properties of the contact lens system 100, such as wearing The size or curvature of the eyeball or the age of the lens wearer. Generally, the total vision correction area of the contact lens system 100 is substantially circular and approximately the diameter Meters to 10 centimeters, preferably about 5 centimeters to 8 centimeters. Electricity can be attached to the contact lens system i 00 by a homogeneous power source such as a battery, capacitor, or other power storage device (c0nf〇rmal sourCe) 190 is provided to the electric actuating element 11 and the rangefinder 13 and the controller. The isomorphic power supply 190 is a thin film made into the shape of a contact lens 120. The shape of the power supply 1 90 may be a ring and attached The contact lens 120 on the outside of the vision correction area can evenly distribute the weight of the power supply throughout the contact lens 120 without disturbing the vision of the wearer. In some specific embodiments, it should be known that the shape of the power supply 19 can be in a ring shape. , But it is generally attached to the contact lens 120 like the stabilizer 145. In these specific embodiments, the weight of the power source 19 can be used to counterbalance to further stabilize the contact lens system i 00 and maintain the distance between the eyelid gaps. Instrument 130. Power supply 1 90 can provide electricity that has been stored in advance, such as batteries. Alternatively, power supply 190 can use electromechanical conversion technology to convert kinetic energy from eye movements to electrical energy. Electrically actuated elements 11 0 At least one focal length provides electro-actuated vision correction. This may include near and / or middle vision, where near- and / or middle-distance vision is the most commonly required focal length for those who require vision correction at multiple focal lengths. The middle-distance vision may be one or both of near-distance vision and far-distance vision. In these specific embodiments, in addition to using adaptive optical instruments by actuating only certain portions of the electrically-actuated elements Electrically-actuated corrective lens wearer's long-distance vision is beyond 87195 -15- 200408850. In addition to the traditional refraction error, long-distance vision is provided by contact lens 120. Eliminating non-traditional refraction errors can correct the vision of the wearer's vision. Therefore, Nanda included correcting the vision of the wearer to be better than 20/10. The area provided by the electronically actuated element 110 for vision correction in the contact lens system 100 may be the same as or smaller than the area provided by the fixed telephoto region 150. In at least one embodiment in which the area of the electrically actuated element 110 is smaller than the fixed remote light region 150, the electrically actuated element 10 covers at least one pupil, and is preferably in the center of the pupil. In some embodiments of the invention, the electrically actuated element 10 is encapsulated before being attached to the contact lens 120. An embodiment of the packaged component i 10 is shown in Fig. 2, which is a cross-sectional view of the contact lens system 1 "shown in Fig. I. A capsule U5 contains an electrically actuated element 110. The contact lens 120 can be molded around the capsule 115 so that the capsule 115 is placed in the body of the contact lens 120. The capsule 115 is substantially circular and is adapted to receive the electro-active element 110. The capsule 115 is optically transparent to light and can be viewed by the wearer through the capsule 115. The capsule 115 is preferably rigid and can be constructed from a non-breathable, water-repellent material or a breathable material. A suitable non-breathable, water-repellent material includes polymethyl methacrylate (commonly known as PMMA). Examples of suitable and rigid breathable materials include methyl methacrylate (MMA) polymerized heteropolymerically with silicone acrylate, or MMA polymerized heteropolymerically with methacryloxypropyl tds (trishydroxymethyl methylamine ktris). . MMA-TRIS is an air-permeable material which is particularly suitable for the capsule film 115. 87195 -16- 200408850 contact lens 120 can be composed of a rigid air-permeable material or an elastic hydrophilic material. Examples of examples of suitable elastic hydrophilic materials include thermo-set polymer hydrogels such as hydroxyethyl methacrylate (HEMA), and dimethyl ether Ethylene dimethacrylate (EDMA) or Ethylene-monogethacrylate (EGDMA), cross-linked hema, siloxane such as dimethysiloxane (PDMS), and other siloxanes Based polymer. Optical grade hydrophilic, breathable, and non-breathable materials, plus those materials, are well known in the 1¾ shape eyewear art. Generally speaking, any of these materials can be used in any combination for the constitution of the capsule 115 or the contact lens 120. However, a combination of a rigid, hydrophilic and / or waterproof capsule with a rigid breathable contact lens or an elastic hydrophilic contact lens is preferred. In some embodiments, the rangefinder 13 (), the controller and the power source may be sealed within the capsule 115 together with the electric actuating element 110, so that all the electronic components of the contact lens system 100 are contained in the capsule. Within the film 115. This may have the advantage of reducing manufacturing costs due to the separable manufacturing and packaging of electronic components. In addition, the bladder tendon 115 may be composed of a water-repellent or waterproof material, or may be sealed with various waterproof sealants, which can provide advantages in that the electronic components are not affected by eyeballs (tears or other secretions). If separated, the capsule can be removed later! i 5 is attached to contact lens i 2 () to produce a contact lens system 100 without having to separately attach rangefinder 13 to contact lens n. . However, it should be known that the placement of the rangefinder 13 in the capsule 115 is not necessary and can be placed on or in the outside of the capsule 87195 at any desired location. In this case, the rangefinder 130 is connected to the electrically actuated element via a contact lens through the capsule II5 and the conductor of the rangefinder 130. In certain embodiments, as shown in FIG. 3, it may be desirable to stabilize the contact lens system 300 using only a single stabilizing sheet 345, such as a single thickener or cymbal weight. At least a part of the single stabilizer 345 is usually attached under the horizontal apex of the contact lens 320. As shown in FIG. 3, the area of potential blur in the contact lens system 300 is reduced by including additional stabilizers. Therefore, a larger area of the 'contact lens system 300 can be used to provide a light source for vision bridge. The availability of additional lens areas to provide vision correction is particularly advantageous in applications such as night vision or other low-light settings. In the case of decreased light, the dilatation of the diaphragm can cause the pupil to expand outside the small vision correction area of the contact lens system 300, causing the possibility of blurred vision or distortion. In yet another exemplary embodiment, as shown in FIG. 4a, the contact lens system 400 is stabilized in an alternative manner without using a stabilizer sheet attached to the contact lens 420. Instead, the contact lens system 400 is stabilized by a truncated contact lens 420. Steady eyeglasses 420 are truncated along a chord 470 below and substantially parallel to the horizontal apex of contact lens 420 in a range of approximately 5 degrees. The chord portion 470 along which the contact lens 420 is shortened is usually located outside the capsule containing the electric actuation element 4 10. The contact lens 420 shortens the leaning string portion 470 to cover the pupil and provide vision correction to the wearer of the lens when the contact lens system 400 is worn without touching the contact lens system 400. Contact lenses 420 are generally truncated by about 5 to 10 87195 -18-200408850 Five to stabilize the contact lens system 400, even if the contact lenses 420 have more or fewer points can be based on the specific vision needs of the wearer And for truncation. The truncation of the contact lens 420 may be sufficient to stabilize the contact lens system 400 and maintain the rangefinder 430 between the eyelid fissures when the contact lens system 400 is worn. Alternatively, one or more stabilizers 445, such as thickeners or puppet weights, can be used in combination with the truncated contact lens 42o, as shown in FIG. 4b, to further stabilize the contact lens system 4o. . In this specific embodiment, the truncation is preferably minimized so that thickened objects or prism weights can be attached to the contact lens 420 to overlap the area providing vision correction in the contact lens system 400. In some specific embodiments, for example, in the case where the vision of a person wearing an electrically actuated contact lens system is in need of astigmatism and correction, the contact lens system may also include a toric power, as shown in FIG. 4a. Further depictions are shown. In these embodiments, the contact lens system 400 is stabilized to maintain the direction of the toric axis 480 of the contact lens 420 and the position of the rangefinder 430. The loose axis 480 is preferably set before the rangefinder 430 is placed on the contact lens 420, such as during the initial manufacturing of the contact lens 420. Alternatively, the rangefinder 430 may first be placed on the contact lens 420 and stabilized, and then the astigmatism axis 480 may be oriented relative to the direction of the rangefinder 430. In some embodiments, the contact lens produces little or no divergence, and the distance vision correction provided by the fixed telephoto zone of the contact lens system can be provided by a capsule containing an electric actuating element. Capsules can be manufactured and surfaced to provide a luminosity directly for long-distance vision correction. As shown in FIG. 5, the contact lens is a skirt 525 made of a hydrophilic material, forming a ring of 87195 -19- 200408850 around the capsule 550, which helps tear flow and reduces the impact on the capsule. Eye and face sensitivity of 550. The contact lens skirt 525 is attached to the capsule 550 only at the periphery 527 of the capsule. The capsule 550 has a radius of curvature that has been surfaced to produce a refractive index that matches the wearer's position for distance vision correction. In the embodiment of Fig. 5, there is a capsule 550 which is not placed in the contact lens body and is surrounded by a contact lens skirt 5 2 5. The contact lens system 500 can be stabilized by thickening, prism weighting, and / or truncation in the same manner described elsewhere. In yet another embodiment, the fixed telephoto power of the contact lens system may be provided by a combination of a contact lens and a capsule. For example, the capsule can be surfaced to have a refractive index and can be placed in the body of a contact lens that also has a refractive index. At the same time, the refractive index can be added to provide a fixed distance photometric to correct the distance vision of the wearer. It should be noted that various other methods, which have been described in the exemplary embodiments of this document, can also be used to stabilize this. These methods can be used in addition to the prism's weighting, thickening and truncation. And astigmatism in contact lenses. Therefore, the specific embodiments described herein have been considered within the scope of the present invention
