Lenzi ya Photochromic ndi lenzi yomwe mtundu wake umasintha ndi kusintha kwa kuwala kwakunja. Imatha kukhala yakuda mwachangu dzuwa likalowa, ndipo kufalikira kwake kumachepa kwambiri. Kuwala kukakhala kolimba, mtundu wa lenzi umakhala wakuda kwambiri, ndipo mosiyana. Lenzi ikabwezeretsedwa m'nyumba, mtundu wa lenzi ukhoza kutha msanga kukhala wowonekera koyambirira.
Kusintha kwa mtundu kumachitika makamaka chifukwa cha kusintha kwa mtundu komwe kumapezeka mkati mwa lenzi. Ndi njira yosinthira ya mankhwala.
Kawirikawiri, pali mitundu itatu ya ukadaulo wopanga ma lens a photochromic: in-mass, spin coating, ndi dip coating.
Magalasi opangidwa pogwiritsa ntchito njira yopangira zinthu zambiri ali ndi mbiri yakale yopangidwa nthawi yayitali komanso yokhazikika. Pakadali pano, amapangidwa makamaka ndi 1.56 index, yomwe imapezeka ndi maso amodzi, bifocal ndi multi-focal.
Kupaka utoto wa spin ndi kusintha kwakukulu pakupanga ma lens a photochromic, kupezeka kwa ma lens osiyanasiyana kuyambira 1.499 mpaka 1.74. Kupaka utoto wa spin photochromic kumakhala ndi mtundu wopepuka, liwiro lachangu, komanso mtundu wakuda komanso wofanana pambuyo posintha.
Kuphimba kwa dip kumatanthauza kumiza lens mu madzi a photochromic, kuti lens iphimbe ndi gawo la photochromic mbali zonse ziwiri.
Universe Optical yadzipereka kufunafuna ma lens abwino kwambiri a photochromic. Ndi luso lamphamvu la R&D, pakhala pali ma lens angapo a photochromic omwe amagwira ntchito bwino kwambiri. Kuchokera ku ma lens achikhalidwe a 1.56 photochromic okhala ndi ntchito yosintha mtundu umodzi, tsopano tapanga ma lens atsopano a photochromic, monga ma lens a blueblock photochromic ndi ma lens a spin coating photochromic.
