Iilensi ze-Optical ze-1.56 eziGqityisiweyo ze-Single Vision Blue Cut Optical
Ngokwesiqhelo, kukho iintlobo ezintandathu ze-refractive index yeelensi ze-resin: 1.50, 1.56, 1.60, 1.67, 1.71 kunye ne-1.74. Ukuba ufuna i-refractive index ephezulu, ungacinga kuphela ngeelensi zeglasi, ezine-1.80 kunye ne-1.90 onokukhetha kuzo. Kuphela kukuba iilensi zeglasi azisetyenziswa rhoqo kule mihla, nangona amaphepha eglasi ekwanazo ne-refractive indices eziphantsi, ezifana ne-1.60 kunye ne-1.71.
