Kev Ceeb Toom Rau Optical Frames

1. Tshem tawm thiab muab cov tsom iav kho qhov muag: Tshem tawm thiab muab tso rau ntawm daim iav txhais ceg ua ke mus rau ob sab ntawm lub ntsej muag. Yog tias koj hnav nws nrog ib txhais tes, nws yuav rhuav tshem qhov sib npaug ntawm sab laug thiab sab xis ntawm tus ncej thiab ua rau deformation.
Tswv yim: Thov tsis txhob siv ntau dhau deformed thav duab, txwv tsis pub qhov deformation ntawm cov thav duab yuav ua rau txhua yam ntawm cov iav kom dhau qhov kev zam ntawm lub teb chaws tus qauv, uas yuav ua rau lub qhov muag deform.
2. Txoj kev tso chaw ntawm cov tsom iav kho qhov muag:
Yog tias cov tsom iav tau muab tso rau ib ntus, thov tig lub convex sab ntawm lub tsom iav; Yog tias koj tso cov iav ntev ntev, thov qhwv cov iav ntaub thiab muab tso rau hauv cov iav tsom iav. Tuav lub hnab looj ntsej muag rau ntawm koj lub pob ntseg thiab co nws maj mam saib seb cov tsom iav puas yog compressed los ntawm cov tsom iav.
Tswv yim: Thov tsis txhob siv lub lens nrog khawb, stains, kab nrib pleb, thiab lwm yam, txwv tsis pub nws yuav ua rau tsis meej pem vim lub teeb tsis zoo. Yog tias qhov no mus, nws yuav ua rau qhov muag tsis pom kev.
3. Cia txoj kev ntawm cov iav kho qhov muag:
Thaum khaws cov tsom iav, tsis txhob sib cuag nrog cov khoom siv corrosive xws li tshuaj tua kab, khoom siv ntxhua khaub ncaws, tshuaj pleev ib ce, tshuaj pleev plaub hau, thiab tshuaj. Txwv tsis pub, cov lo ntsiab muag thiab thav duab yuav deteriorate, deteriorate, thiab hloov xim.
Tswv yim: Yog hais tias lub thav duab los yog lo ntsiab muag muaj cov hws, kua txiv hmab txiv ntoo, tshuaj tsuag plaub hau (tus neeg sawv cev), tshuaj pleev ib ce, thiab lwm yam, thov ntxuav lub tsom iav tam sim nrog cov tshuaj ntxuav qhov muag.
4. Txoj kev ntxuav ntawm cov iav kho qhov muag:
Thaum lub lens yog stained nrog cov plua plav lossis cov khoom qias neeg, cov ntaub so qhuav yog ib qho yooj yim los zom cov lo ntsiab muag, yaug nrog dej thiab tom qab ntawd siv cov ntaub so ntswg los nqus cov dej noo. Yog tias lub lens qias neeg heev, ntxuav cov iav nrog cov tshuaj ntxuav lub lens, tom qab ntawd yaug nrog dej, thiab tom qab ntawd so cov dej nrog cov ntaub so ntswg.
Cov lus qhia: Kev siv cov iav tsom iav tsis tu ncua los ntxuav cov iav, yuav ua rau lub neej ntev ntawm lub lens.
5. Optical spectacle ncej deformation:
Cov iav tsom iav yuav raug deformed tom qab ntau zaus ntawm kev xaiv thiab hnav, thiab lub qhov ntswg los yog pob ntseg yuav hnov ​​​​lub nra hnyav los ntawm deformation ntawm lub ntsej muag iav. Ntau dhau distortion ntawm tus ncej, lub lens yuav poob. Nyob rau hauv cov ntaub ntawv no, thov coj cov iav mus rau lub khw kws tshaj lij, lawv tuaj yeem pab koj.
