Kazhinji, kune marudzi matanhatu erefractive index ye resin lenzi: 1.50, 1.56, 1.60, 1.67, 1.71 uye 1.74. Kana iwe uchida yakakwira refractive index, unogona chete kufunga magirazi lenzi, ane 1.80 uye 1.90 kusarudza kubva. Ingori kuti magirazi lenzi anoshandiswa kashoma mazuva ano, kunyangwe magirazi mashiti anewo yakaderera refractive indices, senge 1.60 uye 1.71.
