Cov tsom iav uas muaj silicone hydrogel muaj ntau yam zoo uas ua rau lawv yog qhov kev xaiv nrov rau ntau tus neeg. Lawv lub ntsiab lus tseem ceeb yog qhov muaj oxygen permeability siab, uas ua rau lub qhov muag ua pa tau yooj yim dua thiab ua kom lub qhov muag noj qab haus huv zoo dua. Cov tsom iav uas muaj silicone hydrogel muaj oxygen permeability siab dua tsib npaug ntawm cov tsom iav ib txwm, ua rau lub qhov muag noj qab haus huv zoo dua thiab txhawb kom hnav tsom iav zoo.

Tsis tas li ntawd xwb, cov iav silicone hydrogel muaj cov dej tsawg, uas txhais tau tias lawv tsis tshua ua rau lub qhov muag qhuav. Lawv muab cov dej tsawg nrog cov pa oxygen ntau, ua rau lawv xis hnav rau lub sijhawm ntev.

Lwm qhov txiaj ntsig yog lawv khaws tau dej noo zoo. Txawm tias hnav ntev ntev los xij, cov iav silicone hydrogel tsis ua rau qhuav. Cov pa oxygen permeability siab thiab cov yam ntxwv khaws tau dej noo ntawm cov iav silicone hydrogel ua rau lawv yog qhov kev xaiv zoo heev rau kev hnav iav ntev.

Txawm li cas los xij, muaj qee qhov tsis zoo uas yuav tsum xav txog. Vim yog ntxiv cov silicone, cov lens no tuaj yeem ruaj khov me ntsis thiab yuav siv sijhawm me ntsis kom paub siv. Cov lens silicone hydrogel kuj suav tias yog cov khoom lag luam siab, uas txhais tau tias lawv yuav kim dua piv rau lwm hom lens.

Thaum piv cov khoom siv silicone hydrogel thiab cov khoom siv tsis-ionic, qhov kev xaiv nyob ntawm tus kheej xav tau. Cov khoom siv tsis-ionic yog qhov tsim nyog rau cov tib neeg uas muaj qhov muag rhiab heev, vim lawv nyias thiab mos, txo qhov kev pheej hmoo ntawm cov protein deposits thiab ua kom lub lens siv tau ntev dua. Ntawm qhov tod tes, cov iav silicone hydrogel yog qhov tsim nyog rau cov tib neeg uas muaj qhov muag qhuav, vim lawv muab cov dej noo zoo dua vim muaj silicone. Txawm li cas los xij, lawv tuaj yeem ruaj khov dua me ntsis. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov neeg uas muaj qhov muag noj qab haus huv yuav pom cov khoom siv lens ib txwm txaus.

Xaus lus, cov iav tsom iav silicone hydrogel yog qhov kev xaiv zoo rau cov tib neeg uas muaj qhov muag qhuav, thaum cov khoom siv tsis-ionic yuav tsim nyog dua rau cov neeg uas muaj qhov muag rhiab heev. Nws raug pom zoo kom sab laj nrog tus kws kho qhov muag kom txiav txim siab cov khoom siv tsom iav zoo tshaj plaws rau koj cov kev xav tau tshwj xeeb.
