I-silicone hydrogel contact lens zineenzuzo ezininzi ezenza zibe lukhetho oludumileyo kubantu abaninzi. Isici sabo esiphambili siphezulu se-oxygen permeability, evumela amehlo ukuba aphefumle ngokukhululekileyo kwaye aqinisekise impilo engcono yamehlo. Iilensi ze-Silicone hydrogel zine-oksijini ekwazi ukutyhubela ngokuphindwe kahlanu kunaleyo yeelensi zoqhagamshelwano eziqhelekileyo, iphucula ngokufanelekileyo impilo yamehlo kunye nokukhuthaza ukunxitywa kwelensi esempilweni.

Ukongeza, iilensi ze-silicone hydrogel zinomxholo ophantsi wamanzi, oko kuthetha ukuba akunakwenzeka ukuba kubangele ukomisa emehlweni. Badibanisa umxholo wamanzi aphantsi kunye ne-oksijeni ephezulu yokungena, okwenza kube lula ukunxiba ixesha elide.

Enye inzuzo kukugcina ukufuma okuphezulu. Nangona ukugqoka ixesha elide, iilensi ze-silicone hydrogel azibangeli ukoma. I-oksijeni ephezulu yokungena kunye nokugcinwa komswakama iilensi ze-silicone ze-hydrogel zibenza babe lukhetho oluhle kakhulu lokunxiba iilensi zexesha elide.

Nangona kunjalo, kukho ezinye iingxaki ekufuneka ziqwalaselwe. Ngenxa yokongezwa kwe-silicone, ezi lens zinokuqina kancinci kwaye zinokufuna ixesha lokuziqhelanisa. Iilensi ze-silicone hydrogel nazo zithathwa njengeemveliso eziphezulu, okuthetha ukuba zinokubiza kakhulu xa kuthelekiswa nezinye iintlobo zeelensi.

Xa uthelekisa i-silicone hydrogel kunye nezinto ezingezona ionic, ukhetho luxhomekeke kwiimfuno zomntu ngamnye. Izinto ezingezizo i-ionic zifanelekile kubantu abanamehlo abukhali, njengoko zincinci kwaye zithambile, zinciphisa umngcipheko wediphozithi zeprotheyini kunye nokwandisa ixesha lokuphila kweelensi. Ngakolunye uhlangothi, iilensi ze-silicone ze-hydrogel zifanelekile kubantu abanamehlo omileyo, njengoko banikezela ukugcinwa komswakama okungcono ngenxa yokufakwa kwe-silicone. Nangona kunjalo, banokuqina kancinci. Kubalulekile ukuqaphela ukuba abantu abanamehlo asempilweni banokufumana imathiriyeli yelensi eqhelekileyo eyaneleyo.

Ukuqukumbela, iilensi zoqhagamshelwano ze-silicone hydrogel lukhetho olulungileyo kubantu abanamehlo omileyo, ngelixa izinto ezingezizo i-ionic zinokulungela ngakumbi abo banamehlo abuthathaka. Kucetyiswa ukuba udibane nengcali yokhathalelo lwamehlo ukuze ubone eyona nto ilungileyo yelens kwiimfuno zakho ezithile.
