    Izinto eziluncedo kwiiLensi zeSalathiso esiPhezulu

    ·Thina. Ngenxa yokukwazi ukugoba ukukhanya ngokufanelekileyo, iilensi ezinesalathiso esiphakamileyo zokujonga kufutshane zineencam ezicekethekileyo kuneelensi ezinamandla achazwe ngugqirha afanayo ezenziwe ngeplastiki eqhelekileyo.

    ·Khaphukhaphu. Amaphethelo amancinci afuna izinto ezincinci zelensi, ezinciphisa ubunzima obupheleleyo beelensi. Iilensi ezenziwe ngeplastiki yesalathiso esiphakamileyo zikhaphukhaphu kuneelensi ezifanayo ezenziwe ngeplastiki yesiqhelo, ngoko ke zikhululekile ngakumbi ukunxiba.

    Yintoni ukukhanya okuBlue?

    Ukukhanya okubonakalayo kuqulethe uluhlu lwamaza obude kunye namandla. Ukukhanya okuluhlaza yinxalenye ye-spectrum yokukhanya ebonakalayo equlethe amandla aphezulu. Ngenxa yamandla ayo aphezulu, ukukhanya okuluhlaza okwesibhakabhaka kunamathuba amaninzi okubangela ingozi kwiso kunezinye izibane ezibonakalayo.

    iilensi eziluhlaza okwesibhakabhaka

    I-spectrum yokukhanya okuluhlaza

    Ukukhanya okuluhlaza okwesibhakabhaka kuluhlu lwe-wavelength kunye namandla ukusuka kwi-380 nm (amandla aphezulu ukuya kwi-500 nm (amandla aphantsi).
    Ngoko ke, malunga nesinye kwisithathu sakho konke ukukhanya okubonakalayo kukukhanya okuluhlaza

    Ukukhanya okuluhlaza kwahlulwa kwakhona kwezi (amandla aphezulu ukuya kumandla aphantsi) amaqela angaphantsi:
    Isibane seViolet (malunga ne-380-410 nm)
    Isibane esiBlue-violet (malunga ne-410-455 nm)
    Isibane esiBlue-turquoise (malunga ne-455-500 nm)

    Ngenxa yamandla abo aphezulu, imitha ye-violet kunye ne-blue-violet iyakwazi ukonakalisa iliso. Ngenxa yesi sizathu, le mitha (380-455 nm) ikwabizwa ngokuba "ngukukhanya okuluhlaza okuyingozi."

    I-blue-turquoise light rays, kwelinye icala, inamandla amancinci kwaye ibonakala inceda ukugcina umjikelo wokulala onempilo. Ngenxa yesi sizathu, le mitha (455-500 nm) ngamanye amaxesha ibizwa ngokuba "inzuzo eluhlaza okwesibhakabhaka."

    Imitha ye-ultraviolet (UV) engabonakaliyo ilele ngaphaya kowona mandla aphezulu (violet) ekupheleni kokukhanya okuluhlaza okwesibhakabhaka imitha ye-UV inobude obufutshane kunye namandla angaphezu kokukhanya okuluhlaza okubonakalayo okunamandla aphezulu. Imitha yeUV ingqinwe iwonakalisa amehlo nolusu.

    iilensi eziluhlaza okwesibhakabhaka

    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.
