1.59 PC Bifocal Invisible Photochromic Grey HMC Optical lenses

Kev Piav Qhia Luv:

Tam sim no, muaj ob hom khoom siv lens hauv khw, ib qho yog iav, lwm qhov yog resin. Cov khoom siv resin muab faib ua CR-39 thiab polycarbonate (PC khoom).

Cov tsom iav bifocal lossis cov tsom iav bifocal yog cov tsom iav uas muaj ob thaj chaw kho tib lub sijhawm thiab feem ntau yog siv los kho qhov muag presbyopia. Thaj chaw deb uas lub tsom iav bifocal kho hu ua thaj chaw deb, thiab thaj chaw ze hu ua thaj chaw ze thiab thaj chaw nyeem ntawv. Feem ntau, thaj chaw distal loj, yog li nws kuj hu ua zaj duab xis tseem ceeb, thiab thaj chaw proximal me, yog li nws hu ua zaj duab xis qis.

Feem ntau cov tsom iav bifocals siv los hloov ob khub tsom iav bifocals uas siv los pom deb thiab pom ze, yog li qhov chaw thiab qhov loj ntawm thaj chaw pom deb thiab thaj chaw pom ze ntawm cov tsom iav bifocals yuav tsum sib xws nrog ob khub tsom iav qub. Yog tias qhov pom ze dua, cov tsom iav subslices yuav loj dua thiab siab dua; Ntawm qhov tod tes, yog tias siv sijhawm ntau dua los saib deb, cov tsom iav subslices yuav me dua thiab qis dua. Tsis muaj ib hom kev tsim qauv twg uas ua tau raws li qhov xav tau ntawm ntau yam xwm txheej. Yuav tsum xaiv thiab phim raws li qhov xav tau ntawm cov neeg hnav, thiab qee zaum yuav tsum siv cov qauv tsim sib txawv kom ua tau raws li qhov xav tau ntawm ntau yam xwm txheej nrog qhov sib txawv loj.
