1.59 PC Blue Block Photochromic Progressive
Kutheni iiLensi zePolycarbonate?
I-Polycarbonate yaphuhliswa ngeminyaka yee-1970 usetyenziso lwe-aerospace kwaye ngoku isetyenziselwa ii-visor ze-helmet zoosomajukujuku kunye ne-windscreens yesiphekepheke.
Iilensi zeglasi yamehlo ezenziwe ngepolycarbonate zaziswa ekuqaleni kweminyaka yoo-1980 ukuphendula imfuno yokukhanya, iilensi ezinganyangekiyo kwimpembelelo.
Ukususela ngoko, iilensi ze-polycarbonate ziye zaba ngumgangatho weeglasi zokhuseleko, izibuko zezemidlalo kunye namehlo abantwana.
Ngenxa yokuba kunqabile ukuba ziphuke kuneelensi zeplastiki eziqhelekileyo, iilensi zepolycarbonate zikwalukhetho olulungileyo loyilo lwempahla yamehlo engenamsinga apho iilensi zincanyathiselwe kumacandelo esakhelo ngokufakwa kwedrill.
ILens Photochromic ephendulayo ngokukhanya
Iilensi zePhotochromicziilensi eziba mnyama xa zibekwe kukukhanya kweultraviolet (UV). Ezi lens zinento ekhethekileyo ekhusela amehlo akho kwisibane se-UV ngokwenza mnyama. Iindondo ziba mnyama ngokuthe ngcembe kwimizuzu embalwa xa uselanga.
Ixesha lokwenza mnyama liyahluka ngokohlobo kunye nezinye izinto ezininzi ezinje ngeqondo lobushushu, kodwa ziye zibemnyama ngaphakathi1-2imizuzu, kwaye ibhloke malunga ne-80% yokukhanya kwelanga. Iilensi zefotochromic zikwakhanyisa ukucaca ngokupheleleyo xa ungaphakathi ngaphakathi kwemizuzu emi-3 ukuya kwemi-5. Ziya kuguquguquka zibe mnyama xa zibonakaliswe ngokuyinxenye kukukhanya kwe-UV - njengosuku olunamafu.
Ezi glasi zilungile xa uphuma kwaye uphuma kwi-UV (ukukhanya kwelanga) rhoqo.
Blue Block Photochromic Lens
Ibhlokhi eBlue
Iilensi zeblowu zephotochromic zenzelwe injongo eyahlukileyo, zinamandla okuthintela ukukhanya okuluhlaza okwesibhakabhaka.
Ngelixa ukukhanya kwe-UV kunye nokukhanya okuluhlaza kungeyonto inye, ukukhanya okuluhlaza kusenokuba yingozi emehlweni akho, ngakumbi ngokuvezwa ixesha elide kwizikrini zedijithali kunye nokukhanya kwelanga ngqo. Konke ukukhanya okungabonakaliyo kunye nokubonakala kancinci kunokuba nemiphumo emibi kwimpilo yamehlo akho. Iilensi zebhlowu zephotochromic zikhusela ngokuchasene nelona nqanaba lamandla liphezulu kumgangatho wokukhanya, okuthetha ukuba zikwakhusela ekukhanyeni okuluhlaza okwesibhakabhaka kwaye zilungele ukusetyenziswa kwekhompyuter.
Uqhubela phambili
Iilensi eziqhubela phambili ziilensi ezihambele phambili kwezobuchwepheshe ezaziwa ngokuba zii-no-bifocals. Kuba, zibandakanya uluhlu oluthweswe isidanga lombono ohluka ukusuka kwindawo ekude ukuya kwindawo ephakathi kunye nekufuphi, evumela umntu ukuba ajonge izinto ezikude nakufuphi nayo yonke into ephakathi. Ziyindleko xa zithelekiswa ne-bifocals kodwa zisusa imigca ebonakalayo kwiilensi ze-bifocal, ziqinisekisa umbono ongenamthungo.
Abantu abaphethwe yiMyopia okanye ukubona kufutshane, banokuzuza kolu hlobo lweelensi. Kuba, kule meko, unokujonga izinto ezikufutshane ngokucacileyo kodwa ezo zikude ziya kubonakala zimfiliba. Ngenxa yoko, iilensi eziqhubekayo zilungele ukulungisa iindawo ezahlukeneyo zombono kunye nokunciphisa amathuba okuba yintloko kunye ne-eyestrain ebangelwa kukusetyenziswa kwekhompyutheni kunye nokugubha.
