DBeyes Silicone Hydrogel Cov Lenses Sib Txuas Lus: Txais Tos Lub Caij Nyoog, Muab 24-Teev Dej Kom Tiv Thaiv Kev Qhuav Thiab Kev Qaug Zog.

Cov tsom iav hydrogel ib txwm muaj kev sib raug zoo ntawm lawv cov dej thiab cov pa oxygen permeability. Coob leej ntau tus xaiv cov tsom iav uas muaj dej ntau dua kom tau raws li lawv cov kev xav tau oxygen.

Thaum lub sijhawm hnav ntev zuj zus, cov dej hauv cov iav tsom iav pib ua pa. Yuav kom tswj tau qib dej uas xav tau, cov iav tsom iav nqus cov kua muag los rov ua kom cov dej noo uas ploj mus. Yog li ntawd, cov neeg siv yuav hnov ​​​​​​qhov muag qhuav thiab tsis xis nyob.

Cov iav tsom iav uas yog silicone hydrogel, ntawm qhov tod tes, yog ua los ntawm cov khoom siv organic polymer uas muaj cov yam ntxwv hydrophilic zoo. Lawv siv cov silicon molecules los tsim cov pa oxygen, uas ua rau cov pa oxygen permeability tsis muaj kev txwv thiab ua rau cov dej molecules hla dhau lub lens thiab mus txog lub qhov muag. Yog li ntawd, lawv cov pa oxygen permeability tuaj yeem ntau dua li cov iav tsom iav ib txwm muaj kaum npaug lossis ntau dua.

Cov iav silicone hydrogel muaj cov pa oxygen permeability siab thiab cov khoom zoo heev rau kev khaws cia noo noo. Txawm tias hnav ntev, lawv tsis ua rau qhov muag qhuav lossis tsis xis nyob. Lawv txhim kho ob qho tib si kev xa oxygen thiab kev xis nyob hnav, muab kev ntseeg siab zoo dua rau kev noj qab haus huv ntawm qhov muag.
