Li-contact tse mebala-bala tsa silicone hydrogel, tse tsejoang hape e le lilense tsa silicone hydrogel, ke mofuta oa lense ea ho kopana e entsoeng ka thepa ea silicone hydrogel. Sechabeng sa kajeno, li-contact tse mebala-bala tsa silicone hydrogel li fetohile mofuta o tsebahalang haholo oa lense ea ho kopana ka lebaka la melemo ea tsona e mengata. Sehloohong sena, re tla tšohla bohlokoa ba li-contact tse mebala-bala tsa silicone hydrogel.

Taba ea pele, li-contact tsa silicone hydrogel tse 'mala li na le oksijene e ngata e kenang. Ho kenella ha oksijene ho bolela bokhoni ba lilense tsa mahlo ho lumella oksijene e lekaneng ho feta ka har'a cornea ho fihla mahlong. Li-contact tsa silicone hydrogel tse 'mala li na le oksijene e ngata e kenang ho feta lilense tsa mahlo tsa setso, ho bolelang hore li ka etsa hore mahlo a phutholohe haholoanyane le ho thibela lefu la mahlo a omileng le mafu a mang a mahlo.

Taba ea bobeli, likhokahano tse 'mala oa silicone hydrogel li na le botsitso le ho tšoarella hamolemo. Ka lebaka la ho tenyetseha ho hoholo le bokhoni ba ho thibela botsofali ba thepa ea silicone hydrogel, likhokahano tse 'mala oa silicone hydrogel li tšoarella haholoanyane 'me li ka sebelisoa nako e telele ho feta lilense tsa puisano tsa setso.

Ho phaella moo, dikotwana tse mmala wa silicone hydrogel di ka fana ka ponahalo ya tlhaho haholoanyane. Thepa ya silicone hydrogel e ka kopana hamolemo le bokahodimo ba cornea, e leng se etsang hore dikotwana tse mmala wa silicone hydrogel di shebahale di le tlhaho le ho fokotsa maikutlo a dibopuwa tse ding mahlong.

Qetellong, li-contact tse mebala ea silicone hydrogel ke mofuta oa lense ea ho kopana e sebetsang hantle, e phutholohileng le e tsitsitseng haholo. Li na le oksijene e kenang hantle, e ka thibelang lefu la mahlo a omileng le mafu a mang a mahlo; li na le bophelo bo bolelele ba ts'ebeletso; 'me li fana ka ponahalo ea tlhaho haholoanyane. Leha ho le joalo, re boetse re hloka ho ela hloko mekhoa le mehato ea ho sebelisa li-contact tse mebala ea silicone hydrogel ho netefatsa bophelo bo botle le polokeho ea mahlo a rona.
