Ama-Speccle Lens afanele amaphutha aphindaphindwayo ngokugoba (ukuqaphela) ukukhanya njengoba kudlula ngelensi. Inani lamakhono okuqashwa okukhanyayo (Amandla welensi) adingekayo ukuhlinzeka ngombono omuhle kukhonjiswa ngomuthi wombukiso onikezwe ngodokotela wakho.
Amaphutha we-Reavuc nama-Lens Powers adingekayo ukuwalungisa alinganiswa kumayunithi abizwa nge-dioptres (D). Uma unwetshwa ngobumnene, umuthi wakho we-lens ungasho -2.00 D. Uma u-myopic kakhulu, ingahle ithi -8.00 D.
Uma udelelekile, udinga ama-Plus "(+) amalensi, akhudlwana enkabeni futhi anciphile emaphethelweni.
Ingilazi ejwayelekile noma ama-lens epulasitiki amanani aphezulu okuncipha noma ukubona isikhathi eside kungaba mkhulu futhi kunzima.
Ngenhlanhla, abakhiqizi badale izinto ezinhlobonhlobo zepulasitiki ezintsha "eziphakeme" ezigobe kahle kahle.
Lokhu kusho ukuthi izinto ezingaphansi zingasetshenziswa ku-lence enama-Index ukuze zilungise inani elifanayo lephutha le-reftive, elenza ama-lens epulasitiki aphezulu anciphile futhi alula kunengilazi evamile noma amalensi epulasitiki.
Izinzuzo zamalensi aphezulu we-Index
Ncamashi
Ngenxa yekhono labo lokugoba ukukhanya ngempumelelo, ama-lens anezinkomba eziphakeme zokuncipha kokuncipha anemiphetho emincane kunama-lens anamandla afanayo kadokotela.
Okokuphemba
Imiphetho emincane idinga impahla ephansi yelensi, enciphisa isisindo selensi. Amalensi enziwe ngepulasitiki ephezulu ye-Index alula kunamalensi afanayo enziwe epulasitiki evamile, ngakho-ke bakhululekile ukugqoka.
Futhi ama-lens amaningi aphezulu ama-Index abuye abe nokwakheka okufanayo, okubanikeza i-slimmer, iphrofayli ekhangayo futhi kunciphisa ukubukeka okukhulisiwe okwenziwa yilensi evamile ebangela imiyalelo enamandla.
Izinketho ze-lens eziphakeme
Ama-lens aphezulu epulasitiki aphezulu aseyatholakala ezinhlobonhlobo ezahlukahlukene zama-indices asusayo, ngokuvamile asukela ku-1.60 kuye ku-1.74. Ama-lens anenkomba evulekayo ngo-1.60 & 1.67 angaba okungenani amaphesenti angama-20 anciphile kunama-lens ajwayelekile epulasitiki, futhi u-1.71 noma ngaphezulu ngokuvamile angaba mncane ngamaphesenti angama-50.
Futhi, ngokuvamile ukukhuluma, okuphezulu kwe-Index, kukhuphuka izindleko zelensi.
Umuthi wakho wokubuka futhi unquma ukuthi hlobo luni lwezinto eziphakeme ze-Index ongafuna ilensi yakho. Izinto eziphakeme kakhulu zezinkomba zisetshenziselwa ngokuyinhloko ngemiyalelo enamandla.
Iningi lemiklamo yelensi yanamuhla ethandwayo kanye nezici - kufaka phakathi i-Dual Aspheric, ethuthuka, i-Bluecut Pro, i-Pitrict I-Photochromic lens- iyatholakala ngezinto eziphakeme.
