I-High Index (inkomba engu-1.74) ilensi yezinto ezibonakalayo iyilensi encane futhi elula kunazo zonke emhlabeni, futhi iyisinqumo esingcono kakhulu semiyalelo yamandla aphezulu, nanoma ubani ofuna ilensi encane kakhulu ukuze ayisebenzise. Zinokuvikelwa kwe-UV okungu-100% futhi zisebenza kahle ngezitayela eziningi zozimele ngaphandle kwe-drilled rimless.
Ukuze uthole umbono nokubukeka okungcono kakhulu, kuwumbono omuhle ukuba ne-anti-reflective lens coating (AR coating) ifakwe kumalensi anenkomba ephezulu. Amalensi anenkomba ephezulu eboshwe nge-AR adlulisa kufikela kumaphesenti angama-99.5 okukhanya esweni ukuze abone kahle.
Futhi ngenxa yokuthi ukufakwa kwe-AR kucishe kuqede ukuboniswa kwamalensi, kwenza amalensi anenkomba ephezulu abonakale ecishe engabonakali, ukuze abanye babone amehlo akho, hhayi amalensi akho.
Ububanzi bokukhanya okuluhlaza okwesibhakabhaka kubude beza namandla asuka ku-380 nm (amandla aphezulu kakhulu ukuya ku-500 nm (amandla aphansi).
Ngakho, cishe ingxenye eyodwa kwezintathu yakho konke ukukhanya okubonakalayo ukukhanya okuluhlaza okwesibhakabhaka
Ukukhanya okuluhlaza kuphinde kuhlukaniswe kulawa (amandla aphezulu ukuya kumandla aphansi):
Ukukhanya kwe-Violet (cishe 380-410 nm)
Ukukhanya okuluhlaza okwesibhakabhaka-violet (cishe 410-455 nm)
Isibani esiluhlaza okwesibhakabhaka-turquoise (cishe 455-500 nm)
Ngenxa yamandla ayo aphezulu, imisebe e-violet kanye ne-blue-violet cishe izolimaza iso. Ngenxa yalesi sizathu, le misebe (380-455 nm) ibizwa nangokuthi "ukukhanya okuluhlaza okulimazayo."
Ngakolunye uhlangothi, imisebe yokukhanya eluhlaza okwesibhakabhaka-turquoise, inamandla amancane futhi ibonakala isiza ukugcina umjikelezo wokulala onempilo. Ngenxa yalesi sizathu, le misebe (455-500 nm) ngezinye izikhathi ibizwa ngokuthi "ukukhanya okuluhlaza okuzuzisayo."
Imisebe ye-ultraviolet (UV) engabonakali ilele ngalé kwesiphetho samandla aphezulu kakhulu (o-violet) we-spectrum yokukhanya okuluhlaza okwesibhakabhaka imisebe ye-UV inobude obufushane wamaza namandla engeziwe kunokukhanya okuluhlaza okwesibhakabhaka okunamandla aphezulu okubonakalayo. Kuye kwafakazelwa ukuthi imisebe ye-UV ilimaza amehlo nesikhumba.
Amalensi okunciphisa ukukhanya okuluhlaza akhiwa kusetshenziswa i-pigment enelungelo lobunikazi engezwa ngqo kumalensi ngaphambi kwenqubo yokusakaza. Lokho kusho ukuthi izinto ezinciphisa ukukhanya okuluhlaza okwesibhakabhaka ziyingxenye yayo yonke impahla yelensi, hhayi nje i-tint noma ukunamathela. Le nqubo enelungelo lobunikazi ivumela ukukhanya okuluhlaza okwesibhakabhaka okunciphisa amalensi ukuthi ahlunge inani eliphezulu lakho kokubili ukukhanya okuluhlaza okwesibhakabhaka nokukhanya kwe-UV.
1. Ukukhanya okuluhlaza kuyo yonke indawo.
2. Imisebe yokukhanya ye-HEV yenza isibhakabhaka sibukeke siluhlaza.
3. Iso alilungile kakhulu ekuvimbeni ukukhanya okuluhlaza okwesibhakabhaka.
4. Ukuchayeka ekukhanyeni okuluhlaza kungase kwenyuse ingozi yokonakala kwe-macular.
5. Ukukhanya okuluhlaza kunomthelela ekucindezelekeni kwamehlo edijithali.
6. Ukuvikela ukukhanya okuluhlaza kungase kubaluleke nakakhulu ngemva kokuhlinzwa kwe-cataract.
7. Akuwona wonke ukukhanya okuluhlaza okwesibhakabhaka okubi.
