Izici Zomkhiqizo
1) Yini ukubaluleka kwelensi enhle eqedwe kancane ekukhiqizeni i-RX?
a.Izinga eliphezulu elifanelekayo ekunembeni kwamandla nasekuzinzeni
b.Izinga eliphezulu eliqeqeshiwe kukhwalithi yezimonyo
c.Izici eziphezulu ze-optical
d.Imiphumela emihle yokufaka imibala kanye nemiphumela yokunamathela eqinile/yokunamathela kwe-AR
e.Qaphela umthamo omkhulu wokukhiqiza
f.Ukulethwa ngesikhathi
Hhayi nje ikhwalithi ekha phezulu, amalensi aqedwe kancane agxile kakhulu kukhwalithi yangaphakathi, njengamapharamitha anembayo futhi azinzile, ikakhulukazi kumalensi amahhala adumile.
2) Ayini ama-Bifocal Lens?
I-Bifocals yimiyalelo emibili ehlanganiswe ibe ilensi eyodwa.
I-Bifocals yaqalwa nguBenjamin Franklin ngekhulu le-18 lapho esika uhhafu wamalensi amabili okubuka futhi ewafaka ohlakeni olulodwa.
Ama-bifocal ayadingeka ngoba izibuko zebanga azanele ukugxila ngokwanele eduze.Njengoba iminyaka ikhula, izibuko zokufunda ziyadingeka ukuze uzifundele kude.Kunokuba akhiphe izibuko ezikude futhi agqoke izibuko eziseduze isikhathi ngasinye, umuntu ofisa ukusebenzela endaweni eseduze angasebenzisa ingxenye engezansi ngokunethezeka.
Kunezinhlobo ezahlukene ze-bifocals ezitholakalayo, kusukela kwe-bifocal eyindilinga-phezulu, i-flat-top bifocal kuya kwe-bifocal ephezulu.
3) Uyini umehluko phakathi kwe-HC, HMC ne-SHC?
Ukugqoka okuqinile | I-AR coating / Hard multi coating | I-Super hydrophobic coating |
yenza ilensi engamboziwe ibe lukhuni futhi ikhulise ukumelana nemihuzuko | kwandisa ukudluliswa kwe-lens futhi kunciphisa ukubonakaliswa kwendawo | yenza i-lens ingangeni manzi, i-antistatic, i-anti slip kanye nokumelana nowoyela |
