Photochromic lens yog lub lens uas xim hloov nrog kev hloov ntawm lub teeb sab nraud. Nws tuaj yeem tig tsaus ntuj sai sai hauv lub hnub ci, thiab nws qhov kev xa mus poob qis heev. Lub teeb muaj zog dua, qhov tsaus xim ntawm lub lens, thiab vice versa. Thaum lub lens muab tso rau hauv tsev, cov xim ntawm lub lens tuaj yeem ploj mus sai sai rov qab mus rau qhov qub pob tshab.
Kev hloov xim yog feem ntau yog taw qhia los ntawm qhov cuam tshuam tsis zoo hauv lub lens. Nws yog ib qho tshuaj reversible tshuaj.
Feem ntau hais lus, muaj peb hom photochromic lens ntau lawm tshuab: hauv-mass, spin txheej, thiab dip txheej.
Lens ua los ntawm txoj kev ntawm kev tsim khoom loj muaj keeb kwm ntev thiab ruaj khov. Tam sim no, nws yog tsim los nrog 1.56 index, muaj nrog ib lub zeem muag, bifocal thiab multi-focal.
Spin txheej yog lub kiv puag ncig hauv photochromic lens ntau lawm, muaj cov lo ntsiab muag sib txawv ntawm 1.499 txog 1.74. Spin txheej photochromic muaj xim xim sib dua, nrawm dua, thiab tsaus dua thiab txawm xim tom qab hloov.
Dip txheej yog txhawm rau txhawm rau lub lens rau hauv cov khoom siv photochromic kua, thiaj li ua rau lub lens nrog cov txheej txheej photochromic ntawm ob sab.
Universe Optical tau mob siab rau kev nrhiav lub lens zoo heev photochromic. Nrog rau qhov muaj zog R & D chaw, muaj ob peb series ntawm photochromic lo ntsiab muag nrog kev ua tau zoo. Los ntawm cov tsoos hauv-mass 1.56 photochromic nrog tib xim hloov muaj nuj nqi, tam sim no peb tau tsim ib co tshiab photochromic lo ntsiab muag, xws li blueblock photochromic lo ntsiab muag thiab spin txheej photochromic lo ntsiab muag.
