Kule mihla, phantse wonke umntu onxibe iiglasi uyazi ilensi yebluecut. Wakungena kwivenkile yeeglasi uze uzame ukuthenga iiglasi, umthengisi/ibhinqa mhlawumbi licebisa iilensi zebluecut, kuba zininzi iingenelo zeelensi zebluecut. Iilensi zeBluecut zinokuthintela ukuxinana kwamehlo nokoma kwamehlo, zinciphise umngcipheko wesifo samehlo kwaye zikunike ubuthongo obungcono… Abathengi bayazi ukuba iilensi zebluecut zilukhetho olufanelekileyo kubo, kodwa kukho iintlobo/iifektri ezininzi zokubonelela ngeelensi zebluecut. Kutheni abathengi bekhetha iilensi zakho? Kutheni iilensi zakho zebluecut zingcono kunezinye?
Kwi-intanethi, kukho iindlela ezininzi kunye neengcebiso zokukufundisa indlela yokujonga ilensi yakho ye-bluecut. Akunakuphikwa ukuba, ezinye iindlela ziya kuxelela ukuba iiglasi zakho ze-blue light zisebenza njengoko bekucetyiwe. Ziluncedo kakhulu ukubona ukuba uninzi lwe-blue light luhluziwe na. Nangona kunjalo, njengomthengisi weelensi ze-Blue light blocking ezithengiswa ngobuninzi nangaphandle, kufuneka wazi indlela yobungcali yokuvavanya iilensi ze-blue light blocking.
Eyona ndlela ikuphela kwayo yokulinganisa ngokuchanekileyo ubungakanani bokukhanya okuluhlaza okwesibhakabhaka okuhluzwa yilensi yebloki yokukhanya okuluhlaza okwesibhakabhaka kukusebenzisa i-spectrophotometer ebonakalayo. Esi sixhobo sinokulinganisa ubungakanani bokukhanya okuluhlaza okwesibhakabhaka ngokuchanekileyo okuphezulu.
Inxalenye ebalulekileyo yendlela olu hlobo lwesixhobo selabhoratri esibizayo esisebenza ngayo kukuba ukukhanya okusetyenziswa ngexesha lovavanyo lwelensi kusemgangathweni. Oku kuthetha ukuba ukukhanya okungenayo kuqulathe yonke imibala efunekayo ukwenza uvavanyo oluchanekileyo.
Ngolu lwazi, kulula ukubona ukuba i-spectrometer ebonakalayo ephathwayo ayinakunika iziphumo zovavanyo oluchanekileyo lohlalutyo lwe-spectral. Naluphi na umlinganiselo othathwayo kusetyenziswa umthombo wokukhanya ongacwangciswanga, njenge-laser pen okanye omnye umthombo wokukhanya ongacwangciswanga awunakuthenjwa.
NgeSpectrophotometer, siza kufumana iingxelo ezichanekileyo malunga nesantya sokuthintela esiluhlaza okwesibhakabhaka, ukudluliselwa kobude be-wavelength nganye…
Njengoko usenokuba uyazi, i-transmittance yelensi ilingana ngokuphambeneyo ne-blue light blocking rate. Xa i-blue light blocking rate iphezulu, i-lens transmittance idla ngokuba phantsi. Ngoko ke ilensi ye-bluecut elungileyo ayipheleli nje ekubeni ne-transmittance ephezulu, kwaye ikwane-blue light blocking rate ephezulu. Ilensi ye-Universe Clear Base Bluecut lukhetho oluhle kakhulu kuwe.Ilensi yeBluecut yeUniverse Clear Baseyenziwe ngezinto ezintsha zelensi zeblueblock kunye netekhnoloji yokuguqula ukugquma okuchasene nokukhanya. Ngezinto ezintsha zokwenza ibluecut kunye nokugquma, okugcina izinga lokuthintela ukukhanya okuluhlaza okwesibhakabhaka lifana nelensi yebluecut yendabuko, ilensi icacile kwaye icacile xa ithelekiswa neelensi zebluecut zemveli.
