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 elungele wena ingase incike ezidingweni zakho zombono, indlela yokuphila, kanye nezintandokazi zakho.
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 aqinile (RGP).Akhululekile futhi aphephe kakhudlwana ukuwagqoka kunezinhlobo zangaphambili zamalensi aqinile njengamalensi e-polymethyl methacrylate (PMMA) endabuko.Amalensi e-PMMA awavamile ukusetshenziswa namuhla.
Amalensi e-RGP enziwe ngezinto zepulasitiki eziguquguqukayo ngokuvamile eziqukethe i-silicone.Le nto engasindi ivumela umoya-mpilo ukuthi udlule ngqo ku-lens uye ku-cornea yeso.
I-cornea yakho iyingqimba yangaphandle esobala kakhulu yeso lakho.I-cornea yakho ikhipha ukukhanya futhi isebenza njenge-lens engaphandle yeso lakho.Lapho i-cornea ingawutholi umoya-mpilo owanele, iyakhukhumala.Lokhu kungaholela ekuboneni okufiphele noma okulufifi, kanye nezinye izinkinga zokubona.
Amalensi e-PMMA awavumeli umoya-mpilo ukuba udlule kumalensi.Okuwukuphela kwendlela umoya-mpilo ongafinyelela ngayo ku-cornea iwukugeleza kwezinyembezi ngaphansi kwelensi njalo uma ucwayiza.
Ukuvumela izinyembezi ukuthi zigeleze ngaphansi kwelensi, amalensi e-PMMA mancane kakhulu.Kufanele futhi kube negebe phakathi kwe-lens ne-cornea.Lokhu kwenza amalensi e-PMMA angakhululeki ukuwagqoka futhi amalensi maningi amathuba okuthi awe, ikakhulukazi ngesikhathi sokuzivocavoca.
Njengoba amalensi e-RGP evumela umoya-mpilo ukuthi udlule, lawa ma-lens makhulu kunamalensi e-PMMA futhi amboza iningi lamehlo.
Ngaphezu kwalokho, imiphetho yamalensi e-RGP inamathela eduze kakhulu ebusweni bamehlo akho.Lokhu kubenza bakhululeke kakhulu ukugqoka kunamamodeli amadala.Iphinde ivumele amalensi 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 ezingezwani nokukhanya 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 anezinkinga ezithile.Nazi ezinye izinkinga ezivamile ngalawa lens.
Uma ufuna ukuthi ama-lens othintana naye aqine isikhathi eside ngangokunokwenzeka, kubalulekile ukuwanakekela kahle.Ukunakekelwa okufanele kwelensi nakho kunganciphisa ingozi yokutheleleka kwamehlo noma imihuzuko ye-cornea.
I-Rigid gas permeable lens (RGP) wuhlobo oluvame kakhulu lwamalensi okuxhumana aqinile anqunywe namuhla.Ngokuvamile zinikeza umbono ocacile kunamalensi okuxhumana athambile.Abuye ahlale isikhathi eside ngokuhamba kwesikhathi futhi ngokuvamile angabizi kakhulu kunamalensi athambile.
Ngaphezu kwalokho, ezinye izimo, kuhlanganise ne-astigmatism, zingalungiswa ngokuphumelelayo ngamalensi okuxhumana aqinile.
Nokho, amalensi okuxhumana aqinile ngokuvamile athatha isikhathi eside ukujwayela futhi angase angakhululeki njengamalensi okuxhumana athambile.Khuluma ne-ophthalmologist yakho ukuze uthole ukuthi yiluphi uhlobo lwelensi yokuxhumana olulungele wena kanye nombono wakho.

Ake sihlole izinto eziyisisekelo zokuthenga amalensi okuxhumana anombala ku-inthanethi kanye nezinketho ezinhlanu ongazizama ukuze ukwazi ukuthenga ngokuzethemba.
Ukubhukuda ngamalensi okuxhumana kungakusiza ukuthi ubone kangcono, kodwa kwandisa ubungozi bezinkinga ezithile zamehlo, kusukela kwamehlo omile kuye kokuqina...
I-Coastal manje isiyi-ContactsDirect.Nakhu ukuthi lokho kusho ukuthini kuwe nokuthi ungawathola kanjani amalensi okuxhumana alungile noma izibuko ngezidingo zakho.
Uma ufuna ukususa ubunzima ekuthengeni izibuko, nansi umbono walokho i-Zenni Optical engakunikezayo.
Sihlukanisa umehluko phakathi kwe-Warby Parker ne-Zenni Optical ukuze sikusize uthole izibuko zakho.
Sihlola uhlelo lokusebenza lwe-GlassesUSA ukuze sibone ukuthi ingakubhalela kanjani incwadi kadokotela yezibuko.Siphinde sabala ezinye izinketho ongazizama.
Amalensi okuxhumana anesaphulelo anikezela ngezinhlobo eziningi zemikhiqizo, amanani aphansi, kanye nokuzulazula kwesayithi okulula.Yini enye okumele ukwazi.
