I-Monovision ligama elinikezwa ubugcisa kunye nesayensi yee-lens zokudibanisa ezifanelekileyo kwizigulane eziye zenza i-presbyopia. I-Presbyopia yinguqu engenakukhutshwa kwimboniso edlalwa kwiminyaka engama-40 ubudala, kubangela ubunzima ekufundeni ukuprintwa okuncinci nokugxila kwizinto ezikufuphi. Uninzi lwabantu luyazi kakuhle iiglasi, i- bifocals okanye iilensi eziqhubekayo njengendlela yokulungisa i-presbyopia .
Eyona nto ingaqhelekanga, nangona kunjalo, umbono ulungisa indlela "ye-monovision." Nge-monovision, iliso elinye lilingane ne-lens ibanga (xa lifuneka) kunye nelinye iliso lihambelane ne-lens esondele, linika umbono ocacileyo kumbono womgama kunye nokufuphi.
I-Monovision isebenza njani?
Ekuboneni kokuqala, i-monovision ibonakala iyimangalisa. Kodwa ngokungavamile njengoko kubonakala ngathi, abaninzi abantu bafumana iziphumo ezimangalisayo. Nantsi indlela esebenza ngayo:
Sonke sinombono obalaseleyo kunye nesiso esingaqhelekanga. (Ungakwazi ukukhawuleza ukujonga iimbono zeli joni ngokukhawuleza .) Xa sibheke kumgama, sisebenzisa umboniso kwilihlo eliphezulu kunokuba sisebenzisa iliso elingabonakaliyo. Iliso elingabonakaliyo lisekhona imisebenzi, kodwa i-eye yohlobo oluthile lithatha. Ingqondo yethu ihlawula ngakumbi ingcaciso ebonakalayo evela kwiso Ngoko ukuba iliso elingabonakaliyo lifakwe ilensi efuphi-futshane yokulungisa umboniso wethu osondeleyo, umbono wethu umgama awuyi kuphazamiseka loo nto.
I-Monovision, ngoko, iquka ukugqoka i- lens yokudibanisa kweso elingaqhelekanga ukulungisa imbonakalo emfutshane, kunye ne-lens yokudibanisa kwiso elona liphezulu (ukuba lifuneka) ukulungisa umboniso wemimandla.
I-Monovision isebenza ngenxa yokuba ubuchopho bukhohlisiwe ekucingeni ukuba i- lens yokudibanisa inxalenye yeliso lendalo. (Ngenxa yeso sizathu, i-monovision ayisebenzisi kwimigangatho yesigqabantso sabaninzi bethu.) Nangona kuthatha iiveki okanye i-2 ukuba ivumelane ne-monovision, ibetha ukufikelela kwiiglasi rhoqo xa ufuna ukufunda.
I-Computer Monovision
Ngekhompyutheni ye-computer, umntu uya kukwazi ukubona kumgama wekrini yecomputer. Uninzi lwabantu abasebenza kwikhompyuthali imihla ngemihla bayonwabela olu hlobo lolungiso, nangona iifesi zokufunda zisenokufuneka. Ikhompyutha ye-monovision ayixhaswa ngokubanzi kubantu abathanda ukufunda ezininzi.
Monovision Modified
Olu hlobo lwe-monovision lunegulane lugqoke enye lensi yokudibanisa eyona nto inobunzima kwiso. Le lensi isetyenziselwa ukubukela izinto ezisondeleyo. Umbono wobunzulu kunye nombono womgama ufikeleleka ngokugqoka i-lens yokubonisana yombono kwelinye iliso.
Monovision LASIK
Izigulane eziye zonwabela i-monovision kunye ne-lens yazo zinoxanduva ziyakwazi ukunandipha izibonelelo ze-monovision LASIK. I-Monovision i-LASIK ijolise ukufezekisa umbono ochanekileyo ofanayo owamkelayo kwi- monovision contact lens, ngaphandle kwama-lens oxhumeneyo emehlweni akho. Kwi-monovision ye-LASIK , iliso elinye lilungiswa kumgama kwaye elinye lisondele. Utyando lwe-LASIK lwenziwa ngqo kwi-cornea. Ukubuyiselwa nokuphulukisa kudla ngokukhawuleza. Ukutshintsha kwimbono kudlalwa kwangoko. Ukuba ucinga ukuba ungathanda ukuzama i-monovision ye-LASIK, ingcinga efanelekileyo ukuqala ukuqinisekisa ukuba ukhululekile ugqoke i-lone contact lens.
Ugqirha kukuzibophezela okukhulu kunye neziphumo kunzima ukuguqula.
ILizwi
Nangona i-monovision ayisebenzeli wonke umntu, kuyindlela enokubakho kubantu abaye banqanda i-presbyopia. I-Monovision inokukunceda ukuba ufezekise kakuhle, umboniso osebenzayo kude nakude. Kodwa "akuphelelanga", nangona kunjalo. Ngokuqhelekileyo kukho ukungcola phakathi kokucaca kumgama okanye kufuphi ukuvumela izigulane zivumelane ngokuthe ngqo kwi-monovision ngeli xesha libonelela ngombono ochanekileyo. Ngenxa yoko, izigulana ezifuna umbono ochanekileyo ulungelelanise kumgama okanye kufuphi kungabi ngabaviwa abafanelekileyo kakhulu kwi-monovision.
Enyanisweni, abantu abangakaze bamele bagqoke iilazi ngokuqhelekileyo abazenzi kakuhle kunye ne-monovision xa kuthelekiswa nabantu abanobuglasi obugqithwe ngaphambili. Ngaphezu koko, i-monovision inokunciphisa ukuqonda okujonge, okuchaphazela i-athletic okanye ukusebenza komsebenzi. Indlela efanelekileyo yokufumana ukuba i-monovision inokusebenzela wena kukubuza ugqirha weziliso lakho. Ukuba i-monovision ayilungele wena, ugqirha weziliso lakho lingabonisa ukuba i-lens (multitifocal) i-lens zokuxhumana, okanye uqhagamshelane nje neelayi ukude kunye nokufunda iiglasi ukuze ugqoke ngaphezu kweelensi zakho zoqhagamshelwano.
