#滑铁卢大学#的眼科诊所正在测试一种新设备，它有朝一日可能有助于预防导致老年人视力丧失的主要起因。科研团队开发了一种设备，可以让验光师看到人眼是如何追踪偏振光的。一个眼睛健康的人可以在他们的视野中以模糊点的形式识别到偏振光——这种现象被称为海丁格刷 (Haidinger's brush)。这是由于黄斑的结构特性，而患有黄斑变性的个人，其黄斑结构会受到损害。如今，黄斑变性通常是在发生不可挽回的视力丧失后才被诊断出来的。物理与天文系的在读博士生Connor Kapahi和IQC变革性量子技术 (TQT) 小组的技术负责人Dusan Sarenac 制造了这台相机，它能够用新形式的光照亮病人的视网膜并为其成像。#加拿大留学[超话]##均融教育 加拿大留学#
