1.71 Umbono omnye iilensi ze-HMC ze-Optical
I-1.71 lens Igama elipheleleyo 1.71 isalathisi se-lens, kunye nesalathisi esiphezulu se-refractive, i-transmittance ephezulu, iimpawu zenombolo ye-Abbe ephezulu, kwimeko ye-myopia degree efanayo, inokunciphisa kakhulu ubukhulu be-lens, ukunciphisa umgangatho we-lens, ngexesha elifanayo. ixesha, yenza ilensi enyulu ngakumbi kwaye eqaqambileyo, akukho lula ukusasaza iinkozo zomnyama. Kufunyenwe ukuba ukongeza i-cyclic sulfide resin kwi-lens material inokuphucula i-refractive index ye-lens, kodwa i-cyclic sulfide resin eninzi iya kukhokelela ekunciphiseni ukuhanjiswa kokukhanya kunye nokuqhekeka kwezinto. Ngokulawula ngokuchanekileyo umxholo we-ring sulfur resin kwi-resin ye-1.71KR, i-lens ye-1.71 ifezekisa isalathisi esiphezulu se-refractive kunye nenombolo ye-abbe ngelixa iqinisekisa ukuhanjiswa kokukhanya okulungileyo, ukusasazeka okuphantsi kunye nombono ocacileyo.
