本(ben)公開是(shi)涉及(ji)具有(you)(you)圓形(xing)(xing)(xing)(xing)光(guang)(guang)(guang)學(xue)(xue)區的(de)(de)前(qian)表面散(san)光(guang)(guang)(guang)軟(ruan)性(xing)隱形(xing)(xing)(xing)(xing)眼(yan)鏡(jing)的(de)(de)設(she)(she)計方法。本(ben)公開描(miao)述(shu)了一種前(qian)表面散(san)光(guang)(guang)(guang)軟(ruan)性(xing)隱形(xing)(xing)(xing)(xing)眼(yan)鏡(jing)的(de)(de)設(she)(she)計方法，其特征在于有(you)(you)圓形(xing)(xing)(xing)(xing)光(guang)(guang)(guang)學(xue)(xue)區，在圓形(xing)(xing)(xing)(xing)光(guang)(guang)(guang)學(xue)(xue)區和非(fei)光(guang)(guang)(guang)學(xue)(xue)的(de)(de)外圍穩定載體(ti)區之間具有(you)(you)平滑過渡。圓形(xing)(xing)(xing)(xing)光(guang)(guang)(guang)學(xue)(xue)區直徑的(de)(de)設(she)(she)計獨立于柱鏡(jing)焦度(du)和背(bei)面的(de)(de)形(xing)(xing)(xing)(xing)狀或(huo)曲率。本(ben)公開描(miao)述(shu)了一種前(qian)表面散(san)光(guang)(guang)(guang)軟(ruan)性(xing)隱形(xing)(xing)(xing)(xing)眼(yan)鏡(jing)的(de)(de)設(she)(she)計方法，使得(de)邊緣分布和光(guang)(guang)(guang)學(xue)(xue)區直徑都(dou)不受球(qiu)鏡(jing)焦度(du)、柱鏡(jing)焦度(du)的(de)(de)大小和/或(huo)柱鏡(jing)軸向的(de)(de)影響。

背景技術：

1、散(san)光(guang)(guang)是(shi)(shi)由于角膜和(he)/或晶(jing)狀體(ti)的球(qiu)面曲率偏差而(er)引起的眼睛屈光(guang)(guang)不正的原因之一(yi)，這會導致視(shi)網膜上的圖像失(shi)真(zhen)，因為來自物體(ti)的光(guang)(guang)線不會匯聚(ju)到(dao)一(yi)個共同的焦(jiao)點，而(er)是(shi)(shi)匯聚(ju)到(dao)一(yi)條(tiao)聚(ju)焦(jiao)線。

2、散(san)光(guang)可與(yu)其他(ta)屈光(guang)不(bu)正(zheng)合(he)并發生，例如近視(shi)(shi)、遠視(shi)(shi)或老花，并在一(yi)定程度上(shang)影響很大(da)比(bi)例的(de)人群。散(san)光(guang)的(de)光(guang)學(xue)矯(jiao)正(zheng)，也稱為柱(zhu)鏡光(guang)學(xue)矯(jiao)正(zheng)，可用于矯(jiao)正(zheng)散(san)光(guang)。因此，患(huan)有近視(shi)(shi)或遠視(shi)(shi)以及散(san)光(guang)的(de)個人可以佩戴軟性隱形眼鏡，該隱形眼鏡在光(guang)學(xue)區(qu)內包括了有球鏡和(he)柱(zhu)鏡設(she)計結(jie)構。

3、散光(guang)的(de)(de)光(guang)學(xue)矯(jiao)正(zheng)(zheng)(zheng)或柱鏡(jing)光(guang)學(xue)矯(jiao)正(zheng)(zheng)(zheng)涉及光(guang)學(xue)特(te)征的(de)(de)使用(yong)，隱形眼鏡(jing)的(de)(de)光(guang)學(xue)區域沿(yan)著彼此(ci)垂直的(de)(de)兩(liang)個方(fang)向具有(you)兩(liang)個不(bu)同的(de)(de)目標焦度(du)(du)(du)。本質上，散光(guang)鏡(jing)具有(you)一個稱為球鏡(jing)焦度(du)(du)(du)的(de)(de)屈光(guang)度(du)(du)(du)，用(yong)于(yu)矯(jiao)正(zheng)(zheng)(zheng)屈光(guang)不(bu)正(zheng)(zheng)(zheng)的(de)(de)近視或遠視，以(yi)及第(di)二(er)個稱為柱鏡(jing)焦度(du)(du)(du)的(de)(de)屈光(guang)度(du)(du)(du)，用(yong)于(yu)矯(jiao)正(zheng)(zheng)(zheng)散光(guang)，這兩(liang)個焦度(du)(du)(du)都設置在隱形眼鏡(jing)光(guang)學(xue)區內(nei)的(de)(de)單個光(guang)學(xue)區域中(zhong)。

4、通(tong)常，鏡片的(de)散(san)光焦(jiao)度可以(yi)通(tong)過在子午角之間連續改變(bian)鏡片的(de)前表面(mian)或(huo)后表面(mian)或(huo)兩者的(de)曲率(lv)半徑來產生。盡管大多數現有(you)技術的(de)散(san)光軟(ruan)(ruan)性隱(yin)形眼(yan)鏡是后表面(mian)散(san)光形式(shi)，但市場上(shang)也有(you)前表面(mian)散(san)光軟(ruan)(ruan)性隱(yin)形眼(yan)鏡，其通(tong)常主要用于晶體性散(san)光。

5、對于(yu)后(hou)表面散(san)光的軟性隱(yin)形(xing)眼鏡，最(zui)小(xiao)的曲率半徑被稱為(wei)(wei)陡峭(qiao)子午(wu)(wu)線，最(zui)大(da)的曲率半徑則被稱為(wei)(wei)平坦子午(wu)(wu)線。按照慣例，平坦子午(wu)(wu)線的方向，即具有最(zui)大(da)正(zheng)焦(jiao)度的子午(wu)(wu)線，是用于(yu)識別后(hou)表面軟性隱(yin)形(xing)眼鏡的散(san)光軸向的。

6、相反，對于前表面(mian)(mian)散光軟(ruan)性隱形眼鏡，鏡片的散光焦(jiao)度(du)是(shi)通過連續改變前表面(mian)(mian)上的曲率半徑而產生的，在這(zhe)種情況下，上述慣例被(bei)倒過來的，即平坦(tan)子午線是(shi)具有最小正焦(jiao)度(du)的子午線。

7、為了實現所需的(de)(de)散(san)(san)光(guang)(guang)矯(jiao)正，鏡(jing)片(pian)柱(zhu)鏡(jing)的(de)(de)軸(zhou)向(xiang)需要與眼(yan)睛(jing)的(de)(de)散(san)(san)光(guang)(guang)軸(zhou)向(xiang)對(dui)齊。散(san)(san)光(guang)(guang)的(de)(de)光(guang)(guang)學(xue)(xue)矯(jiao)正可(ke)用于框(kuang)架鏡(jing)、隱形(xing)(xing)眼(yan)鏡(jing)和人工晶(jing)(jing)狀體矯(jiao)正模(mo)式(shi)中。用于框(kuang)架鏡(jing)片(pian)和人工晶(jing)(jing)狀體的(de)(de)散(san)(san)光(guang)(guang)光(guang)(guang)學(xue)(xue)矯(jiao)正相對(dui)于眼(yan)睛(jing)保持固(gu)定(ding)(ding)。然而，沒有(you)(you)穩定(ding)(ding)功能(neng)的(de)(de)隱形(xing)(xing)眼(yan)鏡(jing)會(hui)在(zai)(zai)眼(yan)睛(jing)上(shang)自然旋轉。因此，散(san)(san)光(guang)(guang)隱形(xing)(xing)眼(yan)鏡(jing)應包括一(yi)個設計(ji)結構，當(dang)佩戴者在(zai)(zai)佩戴散(san)(san)光(guang)(guang)隱形(xing)(xing)鏡(jing)片(pian)時的(de)(de)眨眼(yan)或(huo)環(huan)顧四周時，鏡(jing)片(pian)可(ke)以有(you)(you)正確的(de)(de)方向(xiang)固(gu)定(ding)(ding)著旋轉，使隱形(xing)(xing)眼(yan)鏡(jing)可(ke)以在(zai)(zai)眼(yan)睛(jing)上(shang)保持相對(dui)的(de)(de)穩定(ding)(ding)。

8、散(san)光軟性隱(yin)(yin)形眼(yan)(yan)(yan)鏡的(de)非光學外圍(wei)承載區的(de)特性可(ke)以被(bei)改變(bian)，以保持鏡片在眼(yan)(yan)(yan)上(shang)的(de)方(fang)向。例(li)如，使用被(bei)截面的(de)棱鏡、棱鏡壓載或有目的(de)地(di)增(zeng)厚(hou)散(san)光軟性隱(yin)(yin)形眼(yan)(yan)(yan)鏡下部區域(yu)的(de)周邊，可(ke)以有助于(yu)更好(hao)地(di)穩定散(san)光隱(yin)(yin)形眼(yan)(yan)(yan)鏡。這些方(fang)法在以下現有技術的(de)參考(kao)文獻、美國專利(li)(li)和專利(li)(li)申(shen)請us10747021b2、us6626534b1、us8814350b2和us8646908b2中進(jin)行了描(miao)述。

9、其他穩定(ding)方(fang)法包括軟(ruan)性(xing)散(san)光(guang)隱形眼(yan)鏡的上(shang)下(xia)削薄雙(shuang)層(ceng)板狀設計或(huo)周邊壓載技術。所有(you)這些設計的共同(tong)特征是外圍后表面是旋(xuan)轉對(dui)稱(cheng)的，通(tong)過外圍前表面的旋(xuan)轉不對(dui)稱(cheng)來實(shi)現外圍厚度(du)變化(hua)。傳(chuan)統上(shang)，具有(you)散(san)光(guang)矯正的后表面散(san)光(guang)軟(ruan)性(xing)隱形眼(yan)鏡具有(you)橢圓形的光(guang)學區，其中(zhong)最長軸(zhou)對(dui)應(ying)于具有(you)最大(da)正焦度(du)的子(zi)午(wu)線，而最短(duan)軸(zhou)對(dui)應(ying)于具有(you)最小正焦度(du)的子(zi)午(wu)線。對(dui)于更(geng)高的柱鏡焦度(du)，例如，大(da)于-3.00dc的柱鏡焦度(du)來說，陡(dou)峭子(zi)午(wu)線和(he)平坦子(zi)午(wu)線之間的這種差(cha)異，即(ji)光(guang)區的橢圓率，變得相(xiang)當大(da)，使得難以維持能夠(gou)提供(gong)足夠(gou)的瞳孔覆蓋的光(guang)區直徑，或(huo)者難以提供(gong)良(liang)好舒適性(xing)和(he)眼(yan)位穩定(ding)性(xing)的周邊厚度(du)分(fen)布。

10、本(ben)領域需要一種新的(de)設(she)計方法，該方法有助于為(wei)任(ren)何(he)大小的(de)球鏡和柱鏡焦度(du)以及任(ren)何(he)軸(zhou)向都能保持有合適(shi)直徑(jing)的(de)圓形光學區。
