Isalathiso se-Lens refractive siphezulu, iilensi ezincinci, ubukhulu bobuninzi, ubunzima kwaye bungcono, ngokuchaseneyo, isalathisi esisezantsi se-refractive, i-lens enkulu, i-lens encinci, ukuqina kwakhona kubi, iglasi ngokubanzi yobunzima obuphezulu, ngoko ke isalathisi se-refractive siqhelekile malunga ne-1.7, kwaye ubunzima befilimu ye-resin buhlwempuzekileyo, i-refractive index iphantsi kakhulu, i-resin piece kwimarike okwangoku iyona nto ixhaphakileyo ye-refractive index ye-1.499 okanye kunjalo, Ingcono kancinci i-ultra-thin version, enesalathiso se-refractive malunga ne-1.56 kwaye ikwasetyenziswa kakhulu.
