Ushwankathelo

Iiglasi zepinhole ziiglasi zamehlo ezineelensi ezigcwele iigridi zemingxunya emincinci. Anceda amehlo akho agxile ngokukhusela umbono wakho kwimitha yokukhanya engathanga ngqo. Ngokuvumela ukukhanya okuncinci kwiliso lakho, abanye abantu banokubona ngokucacileyo. Iiglasi zePinhole zikwabizwa ngokuba ziiglasi ze-stenopeic.

Iiglasi zepini zinokusetyenziswa okuninzi. Abanye abantu bayazisebenzisa njengonyango lwe-myopia, ekwabizwa ngokuba kukubona kufutshane. Abanye abantu banxiba kubo ukuzama ukuphucula i-astigmatism.

Abanye abantu bavakalelwa ngamandla ukuba iiglasi zepini ziyasebenza kwezi meko, kodwa ubungqina abukho.

UGqirha Larry Patterson, ugqirha wamehlo waseCrossville, eTennessee uthe: "Kwaye, nangaliphi na ixesha umntu enxiba iiglasi ezinamagingxigingxi athi krwaqu kancinci, abone kude, okanye abe nolwazi nge-astigmatism, [baya] kubona ngokucacileyo [ngeglasi]."

Qhubeka ufunda ukuze ufumane oko sikwazi malunga neiglasi zepini.

Iiglasi zepinki zokuphucula umbono

I-Myopia ichaphazela phantse iipesenti ezingama-30 zabantu e-United States, uqikelela uMbutho waseMelika waseOptometric. Abantu abane-myopia banobunzima bokubona ngokucacileyo ngenxa yemeko yamehlo abo.

Iiglasi zepini azisebenzi ngokwaneleyo ukuba zisetyenziswe yonke imihla ukuba ubona kufutshane. Nangona zikunceda ujonge kwinto ephambi kwakho, zikwathintela inxenye yento oyijongileyo. Awunakho ukunxiba iiglasi zomngxunya xa uqhuba okanye usebenzisa oomatshini.

Patterson, okwangumhleli oyintloko kwezonyango kwiOphthalmology Management, icaphula ukunqongophala kobungqina obunokuthenjwa bokuxhasa ukusetyenziswa kweiglasi zepini ngaphandle kwendawo yezonyango. "Zininzi izinto ezingalunganga, kubandakanya… ukuncipha kombono," utshilo.

Iiglasi zepini zinokuphucula umbono wakho, kodwa okwethutyana. Ukubeka iiglasi zepini kunokuthintela inani lokukhanya elingena kubafundi bakho. Oku kunciphisa intsimi yento oogqirha abathi “sisangqa esibuhlungu” ngasemva kwiretina yakho. Oku kunika umbono wakho ukucaca ngakumbi xa uneiglasi.

Abanye abantu bacinga ukuba ukunxiba iiglasi zepinki ixesha elimisiweyo kusuku ngalunye kunokuphucula umbono wakho ngokubanzi ngokuhamba kwexesha, ngakumbi ukuba ubona kude okanye ubona kude. Akukho bungqina buqinisekileyo okanye izilingo zeklinikhi ezixhasa le nkolelo, nangona kunjalo.

Iiglasi zepinki ze-astigmatism

Iiglasi zepini zinokunceda abantu abane-astigmatism ukuba babone ngcono, kodwa kuphela xa bezinxibile.

I-Astigmatism igcina imitha yokukhanya athe amehlo akho ayifumana kwintlanganiso ekugxilwe kuyo ngokufanayo. Iiglasi zepinhole zinciphisa inani lokukhanya okungena ngamehlo akho. Kodwa iiglasi zephini zikwathintela ukubona kwakho ngokuthintela inxenye yomfanekiso ophambi kwakho.

Kananjalo abanakho ukubuyisela umva kwi-astigmatism. Umbono wakho uza kubuyela kwinto owawuyiyo xa ususa iiglasi.

Olunye unyango lwasekhaya nasekhaya lonyango lwe-myopia

Ukuba unenkxalabo malunga ne-myopia, eyona ndlela isebenzayo yokuphucula umbono wakho kukunxiba iiglasi zokumisela okanye iilensi zonxibelelwano. Ezi zixhobo zokubonelela zinokuqinisekisa ukhuseleko lwakho kunye nokukwazi ukonwabela imisebenzi yemihla ngemihla.

Abanye abantu, utyando lwe-laser lukhetho lokuphucula ukubona kwamehlo. Olunye ukhetho kukuhlinzwa kweLASIK. Isusa izicwili kumaleko angaphakathi e-cornea yakho ukuyila kwakhona iliso lakho.

Olunye ukhetho kukuhlinzwa kwe-laser ye-PRK. Isusa ezinye zeethishu ngaphandle kwe-cornea. Abantu abanamehlo amancinci kakhulu bahlala belungele utyando lwe-laser ye-PRK.

Zombini ezi ntlobo zotyando zinamazinga empumelelo ahlukeneyo, kuxhomekeke kubani owenza utyando kunye nemingcipheko yomntu ngamnye.

I-Orthokeratology lolunye unyango lokungaboni kakuhle. Olu nyango lubandakanya ukunxiba uthotho lweelensi zonxibelelwano ezenzelwe ukumila kwakhona iliso lakho ukuze ubone ngcono.

Ukuba ukungaboni kwakho kusondela ngakumbi ngenxa yoxinzelelo, umsipha olawula indlela iso lakho eligxile ngayo linokuba ne-spasms xa uziva uxinzelelo. Ukuzibandakanya ekunciphiseni uxinzelelo kunye nokuthetha nogqirha malunga nezisombululo ezinokubakho kunokunceda olu hlobo lwe-myopia.

Ezinye izibonelelo zeglasi zepini

Iiglasi zepinki ziyapapashwa njengendlela yokunciphisa amehlo. Kodwa into encinci yafumanisa ukuba iiglasi zepinhole zinokunyusa ubukhulu be-eyestrain ngokubonakalayo, ngakumbi ukuba uzama ukufunda ngelixa uzinxiba. Izifundo ezingaphezulu ziyafuneka ukubona ukuba iiglasi zepinhole ziyichaphazela njani eyestrain.

Ukuba ufumana ilitha ekusebenzeni phambi kwescreen yonke imini, unokucinga malunga nokusebenzisa iiglasi zepinki ukunciphisa ukuqaqamba. Kodwa ukuzama ukusebenza, ukufunda, okanye ukuchwetheza ngelixa unxibe iiglasi kunokuba kungathandeki kwaye kukunike intloko.

Ngamanye amaxesha oogqirha basebenzisa iiglasi zepini njengesixhobo sokuqonda. Ngokukucela ukuba unxibe iiglasi kwaye uthethe ngento oyibonayo, oogqirha ngamanye amaxesha banokumisela ukuba unentlungu kunye nezinye iimpawu ngenxa yosulelo okanye ngenxa yomonakalo kumbono wakho.

Yenza iiglasi zakho zepinki

Unokuzama iiglasi zepini ekhaya usebenzisa izinto osele unazo. Nantsi into oyifunayo:

• iiglasi ezindala ezineelensi ezisusiweyo
• ngefoyile ye-aluminiyam
• inaliti yokuthunga

Gubungela ngokulula izakhelo ezingenanto kwifoyile yealuminium. Emva koko yenza umngxunya omncinci kwifoyile nganye yelensi. Sebenzisa irula ukuqinisekisa ukuba imingxunya emibini iyahambelana. Musa ukubeka umngxuma kwi-foil xa uneiglasi.

Ukuzivocavoca iiglasi zepinki: Ngaba ziyasebenza?

Oogqirha bamehlo bayathandabuza ngokusebenzisa iiglasi zepinki ukusebenzisa amehlo akho. UPatterson uphakathi kwabo.

Kukho imeko enye okanye ezimbini ezingaqhelekanga ezinokuthi ngamanye amaxesha zincedwe ngokwenza umthambo wamehlo. Kodwa oku akunanto yakwenza nokhathalelo lwamehlo, ”utshilo. "Akukho bungqina bunokuthenjwa naphina obucebisa ukuba abantu bangakunciphisa ukubona kude okanye ukubona kude ngokwenza umthambo."

Ngamanye amagama, imithambo eyenziwa ziinkampani ezithengisa iiglasi zemingxunya ayinakuyinyanga okanye inyuse isigxina ukubona kwabantu abadala okanye abantwana.

Iiglasi zepinki zokusithwa kwelanga yinyanga

Ungaze usebenzise iiglasi zepinhole ukujonga ilanga ngexesha lokusithwa kwelanga. Unokwenza iprojektha yakho yepini, nangona kunjalo. Isebenzisa umbono ofanayo wokujolisa amehlo akho ngokuthintela ukukhanya okulahlekeleyo ukujonga ngokukhuselekileyo ukusithwa kwelanga.

Nantsi indlela oyenza ngayo:

1. Sika umngxunya omncinci ekupheleni kwebhokisi yezihlangu. Umngxunya kufuneka ube malunga ne-intshi enye ngapha nangapha komda webhokisi yebhokisi.
2. Emva koko, thepha isiqwenga se-aluminium foil ngaphezulu komngxunya. Sebenzisa inaliti ukwenza umngxunya omncinci kwifoyile xa sele ikhuselekile ebhokisini.
3. Sika iphepha elimhlophe ukuze lingene ngokulula kwelinye icala lebhokisi yezihlangu. Yibhalele ngaphakathi ngaphakathi kwebhokisi yebhokisi. Gcina ukhumbula ukuba ukukhanya okuvela kumngxunya wakho wealuminium kuya kufuneka ulibethe iphepha elimhlophe ukuze ubone ilanga.
4. Kwelinye icala lebhokisi yezihlangu, yenza umngxunya omkhulu ngokwaneleyo ukuba ukwazi ukujonga ngamehlo akho. Lo ngumngxunya wakho wokubukela.
5. Faka isiciko sebhokisi yezihlangu.

Xa ilixesha lokujonga ukusitheka kwelanga, yima ngomqolo elangeni kwaye uphakamise ibhokisi yebhokisi ukuze i-foil aluminium ijonge apho ilanga likhoyo. Ukukhanya kuya kuza emngxunyeni kwaye kuvelise umfanekiso kwi "screen" esimhlophe sephepha kwelinye icala lebhokisi.

Ngokujonga loo mfanekiso ngeprojektha yakho yepini, unokuwukhusela ngokukhuselekileyo wonke umnyama ngaphandle kwengozi yokutshisa i-retina.

Yise kude

Iiglasi zepini zinokusetyenziswa njengesixhobo seklinikhi ukufumanisa imeko ezithile zamehlo. Banokuba yinto eyonwabisayo yokunxiba indlu yakho kunye nesibonelelo esongeziweyo sokuzisa izinto ekugxilwe kuzo ezibukhali.

Kodwa iiglasi zepinhole zivimba kakhulu intsimi yakho yombono kangangokuba akufuneki ukuba inxitywe kuwo nawuphi na umsebenzi ofuna ukubona kwakho. Oko kubandakanya umsebenzi wasekhaya kunye nokuqhuba. Azikhuseli namehlo akho kwimitha yelanga.

Ngelixa iinkampani zithengisa iiglasi zemingxunya yamayeza njengonyango lokungaboni kufutshane, oogqirha bayavuma ukuba abukho ubungqina bezonyango obuchaza ukuba bayasebenza kolu setyenziso.
