Lub lens photochromic yog lub lens uas xim hloov pauv raws li lub teeb sab nraud hloov pauv. Nws tuaj yeem tsaus sai sai thaum nyob hauv tshav ntuj, thiab nws qhov kev xa tawm poob qis heev. Lub teeb muaj zog npaum li cas, lub lens xim tsaus dua, thiab vice versa. Thaum lub lens rov qab rau hauv tsev, lub xim ntawm lub lens tuaj yeem ploj mus rau lub xeev pob tshab qub sai sai.
Qhov kev hloov xim feem ntau yog los ntawm qhov ua rau muaj kev hloov xim hauv lub lens. Nws yog ib qho tshuaj lom neeg uas rov ua tau.
Feem ntau hais lus, muaj peb hom kev tsim cov lens photochromic: hauv pawg, txheej txheej tig, thiab txheej txheej dip.
Cov tsom iav uas ua los ntawm kev tsim ntau hauv pawg muaj keeb kwm tsim khoom ntev thiab ruaj khov. Tam sim no, nws feem ntau yog ua nrog 1.56 index, muaj rau kev pom ib zaug, ob lub qhov muag ob sab thiab ntau lub qhov muag sib txawv.
Kev txheej txheej tig yog kev hloov pauv hauv kev tsim cov iav photochromic, muaj ntau hom iav sib txawv ntawm 1.499 txog 1.74. Kev txheej txheej photochromic tig muaj xim sib dua, nrawm dua, thiab tsaus dua thiab sib npaug tom qab hloov.
Kev txheej txheej yog kev muab lub lens rau hauv cov kua photochromic, yog li ntawd txheej lub lens nrog txheej photochromic rau ob sab.
Universe Optical mob siab rau kev nrhiav cov iav photochromic zoo heev. Nrog rau lub chaw R&D muaj zog, muaj ntau cov iav photochromic nrog kev ua tau zoo heev. Los ntawm cov iav photochromic ib txwm muaj 1.56 nrog kev hloov pauv xim ib zaug, tam sim no peb tau tsim qee cov iav photochromic tshiab, xws li cov iav blueblock photochromic thiab cov iav photochromic spin coating.
