I-1.60 isho ukuthi inkomba ye-refractive ye-lens ingu-1.60, ukuphakama kwe-refractive index, i-lens encane yezinga elifanayo.
I-MR-8 iyilensi ye-polyurethane resin.
1. Phakathi kwawo wonke ama-lens angu-1.60, ukusebenza kwawo kwe-optical kuhle kakhulu, futhi inombolo ye-Abbe ingafinyelela ku-42, okusho ukuthi ukucaca nokuthembeka kokubona izinto kuzoba phezulu;
2. Amandla ayo aqinile angafinyelela ku-80.5, okungcono kunezinto ezijwayelekile zamalensi;
3. Ukumelana nokushisa kwayo kungafinyelela ku-100℃, ukusebenza kuzinzile, ingxenye nayo iphansi.
