Emva kokuba iilensi zenziwe nge-plexiglass, kodwa ngoku ukuveliswa kwazo, i-polrogel polymers isetyenziswa. Ezi zinto zakhiwo eziyinkimbinkimbi kakhulu, zifunyenwe ngexesha lenkqubo enzima. Kule ndawo, ngoku wenze iilensi ezahlukeneyo, kodwa igama lendabuko "i-lens contact" ihlala.
Ngaba ndifuna iimvavanyo ezizodwa ngaphambi kokugqoka iilensi?
Uviwo oluphambili aludingeki. Ugqirha othabatha iilensi zesigulane esenza uvavanyo lweemvavanyo esebenzisa ikhomputha, ngoko uhlola ubunzulu bokubukeka kwimeko efanelekileyo yokulungiswa.

Kukho iintlobo ezimbini zeelensi: ezithambileyo. Iilensi eziphantsi zigqithwe ngabantu abaninzi, ixesha lokutshintsha kwamehlo lifutshane kakhulu. Ngethuba elithile emva kokuqala kokugqoka abantu bade balibale ngokuhlala kwabo. Ukutshintshiselwa ngokuqhelekileyo kuthatha kwiiyure eziliqela ukuya kwiintsuku eziliqela. Ngama-lens anzima kunokuba nobunzima obunzima - ukulutha umlutha kunokuthatha ixesha elide-ukuya kwiiveki ezimbalwa. Kodwa kubo kulula ukulawula izigulane ezingenamava - abaxhomekeke kwiinyembezi nakwezinyembezi.
Ndingaba nexesha elingakanani ukugqoka iilensi?
Enyanisweni, ngaphantsi, ngcono. Uninzi lweentlobo zama-lens oqhagamshelwano kufuneka zisuswe ebusuku. Abanye banokugqithwa ngeveki, imini nobusuku.

Kuhlala kulunge ukusebenzisa i-lotions ukunakekelwa kwabo, ukukwazi ukususa uninzi lwezinto ezingcolileyo. Ukongeza, iifutshane ukugqoka ixesha, ngcono. Xa kuthengiswa sele sele i-lens day-day. Ngelishwa, abuye axabise kakhulu. Ngoko ke, iingcali zincoma ukukhetha i-lens, ixesha lokugqoka elifikelela kwiinyanga ezi-3.
Ngaba iilensi ziyakwazi ukukhusela emisebeni yelanga?
Kakade! Kukholelwa ukuba enye yengozi ye-senile macular degeneration (glaucoma) yimisebe ye-ultraviolet. Ukugqoka ii-lens, kuphelisa umphumo we-UV kwaye ikhusela ngokuthe ngqondweni amehlo ekuhlaleni kwe-retina.

Ukuba iliso elinye linama-diopter eli-7 kunye nelinye liphilile - kufuneka ulungele amehlo kwiso elinye (ukuze ube nombono ochanekileyo webhanyasi.) Uncedo lweglasi alinakwenziwa. Nantsi kwakhona kuza kuncedisa iilensi zokudibanisa.
Emva kokuba usebenze ukususa i-cataract kwelinye iliso kunye nokufakelwa kwe-lens intraocular, kuya kufuneka ugqoke i-diopters ezili-10. Ukuqhagamshelana neelensi kuphela kunokuhlawulela esi siphene.
Emva kokuzalwa komntwana okanye intlungu ebantwini - ngaphandle kokuba iilensi zifakwe. Emva koko, mhlawumbi i-amblyopia iya kuphuhlisa. Ngokusetyenziswa koonxibelelwano lwamalensi ungabona amehlo omntwana ophilileyo.

Emva kokukhipha umzimba wangaphandle kwi-cornea, unxibe iilensi zecala endaweni yeeklasi zokukhanya. Intlungu emva kwalokhu iyancitshiswa kakhulu, kwaye isigulane sibona iso elonakalisiweyo.
Emva kweemichiza kunye nokushisa okufudumeleyo, iilensi zokunxibelelana zinceda iliso liphilise ngokukhawuleza, kwaye intlungu iya kuba ngaphantsi.
