Kev kho lub lens bifocal ntawm presbyopia yog ua ke ob lub diopters sib txawv ntawm tib lub lens kom nws lub lens nrog ob lub zog sib txawv ntawm lub zog refractive, uas yog ob lub ntsiab lus focal. Clinically, feem ntau cov neeg mob muaj ntau hom thiab txawv qib ntawm refractive yuam kev, thiab nyob rau tib lub sij hawm, vim presbyopia, lub zeem muag zeem muag yuav tsum tau nce nyob rau hauv lub ze tshaj degree ntxiv, yog li cov tshuaj txawv lo ntsiab muag yog xav tau rau lub zeem muag deb thiab ze ze ntawm lub zeem muag.
Qhuav Taw Qhia
Dab tsi yog qhov zoo ntawm resin lens? Resin lo ntsiab muag yog ua los ntawm diethylene glycol thiab propylene glycol lipid tshuaj tiv thaiv polymerization. Lub teeb yuag, zoo cuam tshuam tsis kam, kub tsis kam, zoo lub teeb transmittance, ze rau kev ua haujlwm ntawm iav lens, tuaj yeem thaiv cov kab hluav taws xob ultraviolet.
Qhov zoo ntawm PC lo ntsiab muag yog dab tsi? PC lens tseem hu ua: qhov chaw piece lossis qhov chaw, yog ua los ntawm cov khoom siv kho qhov muag PC los ntawm kev txhaj tshuaj molding. Nws muaj lub teeb yuag, muaj zog muaj zog, huab cua tsis zoo, lub teeb xa hluav taws xob zoo, 100% ultraviolet absorption, tsis muaj tshuaj lom, thiab kev tiv thaiv ib puag ncig, nrog rau ntau yam kev loj hlob.
