I-Ultra Thin High Index 1.74 iiLensi
Ziziphi iiLensi ze-1.74 zeSalathisi esiPhezulu?
Ukuba unoMmiselo owomeleleyo kakhulu, kuya kufuneka uqwalasele iilensi ze-Ultra Thin High 1.74.
Isalathiso esiPhezulu 1.74 iilensi zezona lens zibhityileyo, ezithe tyaba, kunye nezona zihonjisiweyo zakha zaphuhliswa.
Ezi lens zibhityileyo ziphantse zibe ngama-40% kuneplastiki kwaye nge-10% zibhityile kune-1.67 yeelensi eziphakamileyo, zikunika eyona nto iphambili kubuchwephesha nakwizinto zokuthambisa. I-lens ebhityileyo iyathandeka kakhulu, inciphisa ukugqwetheka okubangelwa yimimiselo ephezulu xa yenziwe ngeelensi ezikumgangatho ophantsi.
Bubuphi ubungqingqwa belensi endifanele ndikhethe?
Ukuba uphakathi, okanye unombono omfutshane kakhulu uya kuzuza kwiilensi ezibhityileyo njengoko ubukhulu becala lelensi zakho buya kubonakala ngakumbi.
Iilensi ezinesalathiso se-refractive ye-1.6 zifanelekile kwimimiselo apho ixabiso le-SPH yakho ye-SPH liphakathi kwe--2.50 kunye ne-4.00.
Phakathi kwe-4.00 kunye ne-6.00 siya kucebisa i-lens kunye ne-refractive index ye-1.67, kwaye nayiphi na imimiselo engaphezulu kwe-lens ene-refractive index ye-1.74 iya kufaneleka ngakumbi.
Ukuba umyalelo wakho ungaphezulu kwe-5.00 siya kufuna umlinganiselo ochanekileyo womgama phakathi kwabafundi bakho, odla ngokubizwa ngokuba yiPD.
Ngenxa yokuba iilensi zexesha elide kunye nokubona okufutshane zahlukile, kukho ukuqwalaselwa okwahlukeneyo nganye.
I-Hi-index ye-1.74 iilensi zifanelekile
