Ho fapana le likhalase tsa letsatsi tse tloaelehileng kapa lilense tsa photochromic tse fokotsang khanya feela, lilense tsa UV400 li sefa mahlaseli 'ohle a khanya ka maqhubu a bolelele ba li-nanometer tse fihlang ho 400. Sena se kenyelletsa khanya e putsoa ea UVA, UVB le khanya e putsoa e bonahalang e nang le matla a mangata (HEV).
Hore digalase tsa UV di nkuwe e le tsa bohlokwa, dilense di lokela ho thibela 75% ho isa ho 90% ya lesedi le bonahalang mme di lokela ho fana ka tshireletso ya UVA le UVB ho thibela 99% ya mahlaseli a ultraviolet.
Ha e le hantle, o batla likhalase tsa letsatsi tse fanang ka tšireletso ea UV 400 kaha li fana ka tšireletso e ka bang 100% mahlaseling a UV.
Hlokomela hore ha se likhalase tsohle tsa letsatsi tse nkoang e le likhalase tsa letsatsi tse sireletsang mahlaseli a kotsi a UV. Para ea likhalase tsa letsatsi e ka ba le lilense tse lefifi, e leng se ka nahanoang hore se thibela mahlaseli a kotsi, empa seo ha se bolele hore mebala e fana ka tšireletso e lekaneng ea mahlaseli a kotsi a kotsi a UV.
Haeba likhalase tsa letsatsi tse nang le lilense tse lefifi li sa kenyeletse tšireletso ea mahlaseli a kotsi a UV, mebala eo e lefifi e mpe haholo mahlong a hau ho feta ho se apare lieta tse sireletsang mahlo ho hang. Hobaneng? Hobane 'mala o lefifi o ka etsa hore mahlo a hao a bulehe, a pepesetse mahlo a hao khanyeng e eketsehileng ea mahlaseli a kotsi a UV.
Nka tseba joang hore likhalase tsa ka li na le tšireletso ea mahlaseli a kotsi a UV?
Ka bomalimabe, ha ho bonolo ho bona hore na likhalase tsa hau tsa letsatsi kapa lilense tsa photochromic li na le lilense tse sireletsang mahlaseli a kotsi a UV ka ho li sheba feela.
Hape o ke ke wa kgona ho kgetholla bongata ba tshireletso ho latela mmala wa lense, kaha mebala ya lense kapa lefifi ha di amane le tshireletso ya UV.
Ntho e molemohali eo u ka e etsang ke ho isa likhalase tsa hao lebenkeleng la mahlo kapa litsi tsa liteko tsa litsebi. Ba ka etsa teko e bonolo likhalaseng tsa hao ho fumana hore na tšireletso ea mahlaseli a kotsi a kotsi ke bokae.
Kapa khetho e bonolo ke ka ho shebana le moetsi ea tsebahalang le ea nang le boiphihlelo joalo ka UNIVERSE OPTICAL, le ho khetha likhalase tsa letsatsi tsa UV400 tsa 'nete kapa lilense tsa photochromic tsa UV400 leqepheng.https://www.universeoptical.com/1-56-aspherical-uv400-q-active-material-photochromic-lens-product/.
