Description

一种制备高折射率树脂镜片的前弯弯度设计方法
技术领域
本发明涉及一种制备高折射率树脂镜片的前弯弯度设计方法，属于树脂镜片技术领域。
背景技术
树脂镜片具有质轻、抗冲击性好、透光性好、成本低等优点，而且还能满足特殊需要，如增加染色性能、变色性能、防蓝光性能等，甚至可以改变模具设计，比如非球面、渐进多焦点、双面非球面等，所以，越来越受到广大消费者的喜欢。目前，随着电子产品的越来越普及，青少年的近视程度越来越严重，高折射率的树脂镜片也越来越受到欢迎。斜向像散和球镜光度误差对于高折射率的树脂镜片来说，是两个非常重要的指标。这两个重要的指标其关联到镜片前弯弯度是如何设计。
发明内容
本发明的目的在于克服现有技术中的不足，提供一种制备高折射率树脂镜片的前弯弯度设计方法，可以有效地解决镜片成型的几何结构和性能，有效地减小球镜光度误差和斜向像散。
为达到上述目的，本发明是采用下述技术方案实现的：
一种制备高折射率树脂镜片的前弯弯度设计方法，从近视光度-1.00到-15.00范围内，-1.00到-3.50最大的设计前弯弯度是-4.00D；-3.75到-5.50最大的设计前弯弯度是-3.00D；-5.75到-8.75最大的设计前弯弯度是-2.00D；-9.00到-15.00的最大设计前弯弯度是-1.50D。
本发明所述最大设计前弯弯度为镜片几何中心点的弯度。
优选的，所述前弯弯度设计可以用于球面镜片、非球面镜片或多焦点镜片的制备。
优选的，所述高折射率镜片为折射率为1.60、1.67或1.74的镜片。
优选的，所述折射率为1.60的镜片的单体可以为2,5(或2,6)-双(异氰酸酯基甲基)双环[2.2.1]庚烷、六亚甲基二异氰酸酯、四(3-巯基丙酸)季戊四醇酯和4-巯甲基-3,6-二硫杂-1,8-辛二硫醇的混合物，催化剂为有机锡类催化剂。
优选的，所述折射率为1.67的镜片的单体可以为1,3-二(异氰酸基甲基)苯和双(巯甲基)-3,6,9-三硫杂十一烷-1,11-二硫醇，催化剂为有机锡类催化剂；
优选的，所述折射率为1.74的镜片的单体可以为双(2,3-环硫丙基)二硫化物和双(巯甲基)-3，6，9-三硫杂十一烷-1，11-二硫醇，催化剂为胺类催化剂。
SEQ是感知平均球体和期望球体之间的差异。CYL是每片镜片产生的斜向散光。SEQ和CYL和镜片的前弯有很大的关系，前弯越大，其SEQ越小，CYL越好。为了进一步降低斜向散光，需要更深的前弯。因此，SEQ误差会少量的增加。对于70mm直径的1.67树脂镜片，更深的前弯会造成边缘厚度的增加，但是也只是很小量的增加。
与现有技术相比，本发明所达到的有益效果：
本发明提供了一种制备高折射率树脂镜片的前弯弯度设计方法，限制了其最大设计前弯的弯度，可以有效地解决镜片成型的几何结构和性能，能够最大限度地减小球镜光度误差和斜向像散。
