Uma ukhetha ukugqoka amalensi okuxhumana esikhundleni sezibuko ukuze uthuthukise umbono wakho, kunezinhlobo ezimbalwa ongakhetha kuzo.
Womabili ama-contact lens aqinile nathambile anezinzuzo zawo kanye nokubi.Iyiphi ekulungele ingase incike ezidingweni zakho zokubona, indlela yokuphila kanye nezinto ozikhethayo.
Uma ucabangela ama-lens aqinile, funda ukuze ufunde ngobuhle nobubi balawa ma-lens nokuthi angawasebenzisa kanjani ngokuphepha.
Uhlobo oluvame ukusetshenziswa kakhulu lwamalensi okuxhumana aqinile amalensi e-rigid gas permeable (RGP) .
Amalensi e-RGP enziwe ngezinto zepulasitiki eziguquguqukayo ngokuvamile ezihlanganisa i-silicone. Le nto engasindi ivumela umoya-mpilo ukuthi udlule ngqo ku-lens uye ekhoneni leso lakho.
I-cornea yakho iyingqimba engaphandle esobala yeso lakho. I-cornea yakho ihlanza ukukhanya futhi isebenza njenge-lens engaphandle yeso lakho. ezinye izinkinga zamehlo.

Amalensi e-PMMA awavumeli umoya-mpilo ukuba udlule kumalensi.Ukuphela kwendlela umoya-mpilo ongafinyelela ngayo ekhoneni iwukuba izinyembezi ziphuma ngaphansi kwelensi njalo lapho ucwayiza.
Ukuze uvumele izinyembezi ukuthi zihambe ngaphansi kwelensi, amalensi e-PMMA mancane kakhulu ngosayizi.Futhi, kufanele kube negebe phakathi kwelensi nekhone.Lokhu kwenza amalensi e-PMMA angakhululeki ukugqokwa, futhi namalensi maningi amathuba okuthi aphume. , ikakhulukazi lapho uzivocavoca.
Ngenxa yokuthi amalensi e-RGP avumela umoya-mpilo ukuthi udlule kuwo, lawa ma-lens makhulu kunamalensi e-PMMA futhi amboza ngaphezulu iso.
Ukwengeza, imiphetho ye-lens ye-RGP ihambisana eduze nendawo yamehlo akho.Lokhu kubenza bakhululeke kakhulu ukugqoka kunamamodeli amadala.Kubuye kuvumela ama-lens ukuthi ahlale emehlweni akho ngokuphepha.
Amaphutha e-refractive enzeka lapho ukuma kweso lakho kuvimbela ukukhanya okungenayo ukuthi kugxile kahle ku-retina.I-retina iwungqimba lwezicubu ezizwela ukukhanya ngemuva kweso.
Ukugqoka amalensi okuxhumana aqinile e-RGP kungalungisa izinhlobo ezimbalwa zamaphutha e-refractive, okuhlanganisa:
Amalensi okuxhumana aqinile e-RGP anezinzuzo ezimbalwa ngaphezu kwamalensi okuxhumana athambile.Ake sibheke lezi zinzuzo ngokuningiliziwe:
Amalensi okuxhumana aqinile e-RGP nawo anobubi obuthile.Nazi ezinye izinkinga ezivamile ngalawa ma lens.
Uma ufuna ukuthi ama-lens aqinile asebenze isikhathi eside ngangokunokwenzeka, kubalulekile ukuwanakekela.
Amalensi e-Rigid gas permeable (RGP) awuhlobo oluvame kakhulu lwamalensi okuxhumana aqinile anqunywe namuhla.Ngokujwayelekile ahlinzeka ngombono obukhali, obukhali kunamalensi okuxhumana athambile.Ahlala isikhathi eside ngokuhamba kwesikhathi futhi ngokuvamile awabizi kakhulu kunamalensi athambile.

Futhi, ezinye izimo, kuhlanganise ne-astigmatism, zingalungiswa ngokuphumelelayo ngamalensi okuxhumana aqinile.
Nokho, ukugqoka amalensi okuxhumana aqinile ngokuvamile kuthatha isikhathi eside ukujwayela, futhi angase angakhululeki njengamalensi okuxhumana athambile.Khuluma nodokotela wakho wamehlo ukuze uthole ukuthi yiluphi uhlobo lwelensi yokuxhumana olulungele wena kanye nezidingo zakho zombono.
Ukubhukuda ngamalensi okuxhumana kungakusiza ukuthi ubone kangcono, kodwa kwandisa ubungozi bakho bezinkinga ezithile ezihlobene namehlo, ukusuka kweso elomile kuye kubucayi...
Oxhumana Nabo Abanesaphulelo banikela ngezinhlobo eziningi zemikhiqizo, amanani aphansi uma kuqhathaniswa, kanye nokuzulazula kwewebhusayithi okulula ukukusebenzisa.Yikuphi okunye okumele ukwazi lapha.
Ziningi izindawo zokuthenga izibuko ku-inthanethi.Abanye banezitolo lapho ungathenga khona futhi.Abanye bathembele ekufakweni okubonakalayo nasezivivinyweni zasekhaya.
Uma ubheke ukuthenga amalensi okuxhumana ku-inthanethi, amasayithi akulolu hlu anerekhodi elilandelanayo lokwaneliseka kwamakhasimende kanye nokuphatha amalensi okuxhumana ekhwalithi...
