Ang silicone hydrogel ay isang organikong polymer na materyal na ginagamit sa paggawa ng contact lens. Kinikilala na ito ngayon bilang ang nangungunang high-oxygen permeable contact lens material. Pinagsasama ang hydrophilicity at lambot ng mga tradisyonal na hydrogel na materyales na may pinahusay na paghahatid ng oxygen, ang silicone hydrogel contact lens ay nagbibigay ng mas mahusay na proteksyon para sa kalusugan ng mata .


The pagbuo ng mga corneal contact lens ay nakakita ng silicone hydrogel na naging isang pangunahing tagumpay sa parehong mga materyales at teknolohiya ng pagmamanupaktura. Habang ang mga tradisyunal na hydrogel lens ay dating nangingibabaw sa merkado sa kanilang mahusay na kaginhawahan at hydrophilic properties, mayroon silang likas na mga kahinaan. Kabilang dito ang mas mabilis na pagsingaw ng kahalumigmigan na kadalasang humantong sa pagkatuyo ng mata .


By ng pagsasama ng mga bahagi ng silicone sa tradisyonal na base ng hydrogel, nalutas ng mga tagagawa ang pangunahing isyu na ito. Dahil ang oxygen ay may napakataas na solubility sa silicone, ang oxygen permeability ay hindi na nakadepende lamang sa nilalaman ng tubig. Ang inobasyong ito ay epektibong tumugon sa problema sa moisture evaporation na sumakit sa mga naunang disenyo ng contact lens .


The proseso ng pag-alis para sa silicone hydrogel contact lens ay sumusunod sa parehong pamamaraan tulad ng mga regular na lente. Gayunpaman, maaaring makita ng ilang nagsusuot na bahagyang mas mahirap ang pag-alis dahil sa pinahusay na pagpapanatili ng kahalumigmigan ng mga lente at mas makinis na ibabaw. Para sa mas madaling pag-alis, dahan-dahang ilipat ang lens mula sa kornea patungo sa puting bahagi ng iyong mata bago ito kurutin gamit ang iyong hinlalaki at hintuturo. Ang pagpapanatiling tuyo ng iyong mga daliri ay nagpapataas ng alitan para sa mas madaling paghawak. Palaging iwasan ang paggamit ng mga kuko na maaaring scratch sa lens o cornea .


Despite kanilang mga pakinabang, ang mga silicone hydrogel lens ay may mga limitasyon. Ang materyal ay may posibilidad na makaakit ng mas maraming deposito ng lipid at protina sa paglipas ng panahon, na maaaring makaapekto sa parehong visual na pagganap at ginhawa sa pagsusuot. Ito ang dahilan kung bakit ang karamihan sa mga silicone hydro
