    ·Zombini isalathisi esiphezulu se-refractive kunye nenombolo ephezulu ye-Abbe zibonelela ngokusebenza kwamehlo okufana neelensi zeglasi.
    ·Imathiriyeli yenombolo ye-Abbe ephezulu efana ne-MR-8 inciphisa ukusebenza kweprism (i-chromatic aberration) yeelensi kwaye ibonelela ngokusetyenziswa ngokukhululekileyo kubo bonke abanxibayo.

    Yintoni ukukhanya okuBlue?

    Ukukhanya kwelanga kuqulethe imitha yokukhanya ebomvu, e-orenji, emthubi, eluhlaza naluhlaza okwesibhakabhaka kunye nemithunzi emininzi yalo mbala ngamnye, ngokuxhomekeke kumandla kunye nobude bemitha yemitha nganye (ekwabizwa ngokuba yimitha yombane yombane). Idityanisiwe, le mitha yokukhanya enemibala idala into esiyibiza ngokuba "kukukhanya okumhlophe" okanye ukukhanya kwelanga.

    Ngaphandle kokungena kwifiziksi entsonkothileyo, kukho ubudlelwane obuguqukileyo phakathi kobude bemitha yokukhanya kunye nobungakanani bamandla abakuwo. Imitha yokukhanya enobude bamaza amade ngokwentelekiso iqulethe amandla amancinane, yaye leyo inobude obufutshane bamaza inamandla angakumbi.

    Imitha ekwisiphelo esibomvu sokukhanya okubonakalayo kunobude obude kwaye, ngenxa yoko, amandla amancinci. Imitha ekwisiphelo esibhlowu sespectrum inobude obufutshane kunye namandla amaninzi.

    Imitha ye-electromagnetic ngaphaya kwesiphelo esibomvu sokukhanya okubonakalayo kubizwa ngokuba yi-infrared - iyafudumala, kodwa ayibonakali. ("Izibane zokufudumala" ozibonayo zigcina ukutya kushushu kwindawo otyela kuyo zikhupha imitha ye-infrared. Kodwa ezi zibane zikwakhupha ukukhanya okubomvu okubonakalayo ukuze abantu bazi ukuba zikhanya! Kunjalo nakwezinye iindidi zezibane zobushushu.)

    Ngakolunye uhlangothi lwe-spectrum yokukhanya okubonakalayo, imitha yokukhanya eluhlaza okwesibhakabhaka kunye namaza amafutshane amafutshane (kunye namandla aphezulu) ngamanye amaxesha kuthiwa yi-blue-violet okanye ukukhanya kwe-violet. Yiloo nto imitha ye-electromagnetic engabonakaliyo ngaphaya nje kwe-spectrum yokukhanya ebonakalayo ibizwa ngokuba yimitha ye-ultraviolet (UV).

    Amanqaku aphambili malunga nokukhanya okuBlue

    1. Ukukhanya okuluhlaza kuyo yonke indawo.
    2. Imitha yokukhanya ye-HEV yenza isibhakabhaka sibonakale sizuba.
    3. Iliso alikho kakuhle kakhulu ekuthinteleni ukukhanya okuluhlaza.
    4. Ukukhanya okuluhlaza okuluhlaza kunokunyusa umngcipheko wokwehla kwe-macular.
    5. Ukukhanya okuluhlaza okwesibhakabhaka kunegalelo kwi-digital eye strain.
    6. Ukukhuselwa kokukhanya okuluhlaza okwesibhakabhaka kunokubaluleka ngakumbi emva kokuhlinzwa kwe-cataract.
    7. Ayizizo zonke izibane eziluhlaza ezingalunganga.

    Indlela iBlue Light yokunciphisa iiLens inokunceda

    Iilensi zokunciphisa ukukhanya okuluhlaza zenziwe kusetyenziswa i-pigment enelungelo elilodwa lomenzi wechiza eyongezwa ngokuthe ngqo kwilensi phambi kwenkqubo yokuphosa. Oko kuthetha ukuba izinto eziluhlaza okwesibhakabhaka zokunciphisa ukukhanya yinxalenye yezinto zonke zelensi, kungekhona nje i-tint okanye i-coating. Le nkqubo inelungelo elilodwa lomenzi wechiza ivumela ukukhanya okuluhlaza okwesibhakabhaka ukunciphisa iilensi ukuhluza inani eliphezulu lokukhanya okuluhlaza kunye nokukhanya kwe-UV.
