I-lensedy yeelebhu ezichanekileyo ezichanekileyo ngokugoba (ukwala) ukukhanya njengoko kudlula kwilensi. Isixa sokukhanya kokukhanya okukhanyayo (i-lens yamandla) efunekayo ukubonelela umbono olungileyo uboniswa kwisitayile esinikezwe sinikezwe ngugqirha wakho wamehlo.
Iimpazamo ezihlaziyiweyo kunye neelensi ezifunekayo ukuba zilungiselele zilinganiswa kwiiyunithi ezibizwa ngokuba yi-diopres (d). Ukuba unobulali obufutshane, i-lens yakho i-lens inokuthetha -2.00 D. ukuba ungoyena mzi, unokuthi -8.00 D.
Ukuba ungolula, uyafuna "dibanisa" (+) iilensi, ezinokuthambisa embindini kwaye zithambile emaphethelweni.
Iglasi yesiqhelo okanye iilensi zeplastiki zexabiso eliphezulu lokugxininisa okufutshane okanye uxinzelelo olude lunokuba lukhulu kwaye lunzima.
Ngethamsanqa, abavelisi badala iintlobo zeplastiki ezitsha zeplastiki ezibonisa izixhobo ezikhanyayo ngakumbi.
Oku kuthetha ukuba izinto ezingaphantsi zisetyenziswe kwi-lensicli-index ye-Index ukulungisa inani elilinganayo lempazamo ehlaziyiweyo, eyenza i-lenses ephezulu yeplasitiki yeplasitiki kwaye ilula kuneglasi yesiqhelo okanye i-lenser eqwiniweyo.
Izibonelelo zeZilonda zeLinga eliPhakamileyo
Mncinci
Because of their ability to bend light more efficiently, high-index lenses for shortsightedness have thinner edges than lenses with the same prescription power that are made of conventional plastic material.
Ilula
Imiphetho enqamlezileyo ifuna i-lens encinci, enciphisa ubunzima belenses. Iilensi zenziwe ngeplasitiki ephezulu zilula kunezilensi ezifanayo ezenziwe ngeplastiki eqhelekileyo, ngoko ke zikhululekile ukuba zinxibe.
Kwaye uninzi lweelensi eziphakamileyo zinelungelo lokuyila, ebanika iprofayile yomtsalane, ngakumbi kwaye unciphise i-lenseds ebonakalayo jonga imigqaliselo eqingqiweyo.
Isalathiso esiphakamileyo se-Lens
Iilensi zeplasitiki eziphakamileyo zifumaneka ngeendlela ezahlukeneyo zokuhlaziya ii-Indices, zihlala zisusela kwi-1.60 ukuya kwi-1.74. Iilensi ezinesalathiso se-1.60 kunye ne-1.67 zinokuba ngama-20 eepesenti zinokunemilane yeplastiki, kunye ne-1.71 okanye ngaphezulu i-50 pesenti inokuthi ijikeleze ipesenti ezingama-50.
Kwakhona, ngokubanzi, i-Indenti yesalathiso iphakame, iphakame iindleko zeelensi.
UMBONO WAKHO WOKUGQIBELA KUPHELA KUPHELA KUPHELA IZENZO ZENKXASO-siseko esiPhezulu onokuyifuna kwilensi yakho. Ezona zixhobo ziphezulu zesalathiso zisetyenziswa ikakhulu kwimigqaliselo eyomeleleyo.
Uninzi lweeleyili zelensi zanamhlanje ezithandwayo kunye neempawu-kubandakanya i-ofisi yesibini, inkqubela phambili, i-Geagecut Pro, i-rinta i-ted, kunye ne-interchromic lenses ye-Spin.
