    Izinzuzo zamalensi anenkomba ephezulu

    ·Mncane. Ngenxa yekhono lawo lokugoba ukukhanya kahle kakhulu, amalensi anenkomba ephezulu yokubona eduze anemiphetho emincane kunamalensi anamandla afanayo kadokotela enziwe ngezinto ezivamile zepulasitiki.

    ·Kalula. Amaphethelo azacile adinga i-lens encane, enciphisa isisindo sonke samalensi. Amalensi enziwe ngepulasitiki enenkomba ephezulu alula kunamalensi afanayo enziwe ngepulasitiki evamile, ngakho-ke kulula kakhulu ukuwagqoka.

    Kuyini Ukukhanya Okuluhlaza?

    Ukukhanya okubonakalayo kuqukethe ububanzi bamaza namandla. Ukukhanya okuluhlaza okwesibhakabhaka ingxenye yobubanzi bokukhanya obubonakalayo obuqukethe amandla aphakeme kakhulu. Ngenxa yamandla ako aphezulu, ukukhanya okuluhlaza okwesibhakabhaka kunamandla amaningi okubangela ukulimala kweso kunokunye ukukhanya okubonakalayo.

    I-spectrum yokukhanya okuluhlaza okwesibhakabhaka

    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.

    Amaphuzu Abalulekile Mayelana Nokukhanya Okuluhlaza

    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.

    Indlela Amalensi Okunciphisa Ukukhanya Okuluhlaza Angasiza Ngayo

    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.
