Isalathiso esiPhakamileyo (i-1.74 index) imathiriyeli yelensi yeyona nto incinci kwaye ikhaphukhaphu lens emhlabeni, kwaye lolona khetho lubalaseleyo kwimiyalelo yamandla aphezulu, okanye nabani na ofuna eyona lens incinci kwisicelo sabo. Banokhuseleko lwe-UV oluyi-100% kwaye basebenza kakuhle kunye nezitayile ezininzi zesakhelo ngaphandle kwe-drilled rimless.
Ngowona mbono ubalaseleyo kunye nenkangeleko, luluvo oluhle ukuba ne-anti-reflective lens coating (i-AR coating) ifakwe kwiilensi zesalathisi esiphezulu. Iilensi ze-AR-coated high-index zithumela ukuya kuthi ga kwi-99.5 ipesenti yokukhanya kwiliso ukuze ubone kakuhle.
Kwaye ngenxa yokuba ukugquma kwe-AR kuphelisa ukubonakaliswa kweelensi, kwenza iilensi ezinesalathiso esiphakamileyo zibonakale ziphantse zingabonakali, ukuze abanye babone amehlo akho, hayi iilensi zakho.
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 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.
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.
