Ukubuka konke

Izibuko ze-Pinhole zivame ukuba yizibuko zamehlo ezinamalensi agcwele igridi yezimbobo ezincane. Zisiza amehlo akho agxile ngokuvikela umbono wakho emisebeni yokukhanya engaqondile. Ngokuvumela ukukhanya okuncane esweni lakho, abanye abantu bangabona ngokucacile. Izibuko zePinhole zibizwa nangokuthi izibuko ze-stenopeic.

Izibuko ze-Pinhole zinokusetshenziswa okuningana. Abanye abantu bayazisebenzisa njengokwelapha i-myopia, eyaziwa nangokuthi ukubona eduze. Abanye abantu bazigqoka ukuzama ukuthuthukisa i-astigmatism.

Abanye abantu banomuzwa onamandla wokuthi izibuko zembotshana yesikhumba zisebenza kule mibandela, kepha ubufakazi abukho.

"Odokotela bamehlo, odokotela bamehlo kanye nodokotela wamehlo, emashumini amaningi eminyaka basebenzise izingilazi zepinki emtholampilo ukusiza ukuthola izinto ezithile ngamehlo esiguli lapho kwenziwa imitholampilo," kusho uDkt Larry Patterson, udokotela wezifo zamehlo osebenza eCrossville, eTennessee. "Futhi yebo, noma nini lapho umuntu egqoka izingilazi zemigodi ecishe ibonwe kancane, obona kude, noma one-astigmatism, [uzobona] ngokucace kakhudlwana [enezibuko]."

Qhubeka ufunde ukuze uthole ukuthi yini esikwaziyo ngezingilazi zepinki.

Izibuko ze-Pinhole zokwenza ngcono umbono

IMyopia ithinta cishe abantu abangamaphesenti angama-30 e-United States, kulinganisela i-American Optometric Association. Abantu abane-myopia banenkinga yokubona kahle ngenxa yokuma kwamehlo abo.

Izibuko ze-pinhole azisebenzi ngokwanele ukusetshenziswa kwansuku zonke uma ubonela eduze. Noma zikusiza ukuthi ugxile entweni ephambi kwakho, zivimba nengxenye yalokho okubukayo. Awukwazi ukugqoka izingilazi ze-pinhole ngenkathi ushayela noma usebenzisa imishini.

Patterson, obuye abe ngumhleli omkhulu wezokwelapha we-Ophthalmology Management, icaphuna ukungabi bikho kobufakazi obuthembekile bokuxhasa ukusetshenziswa kwezingilazi ze-pinhole ngaphandle kwesizinda somtholampilo. "Kunezinto eziningi ezimbi, kufaka phakathi… ukwehliswa kombono wangaphandle," esho.

Izingilazi ze-Pinhole zingathuthukisa umbono wakho, kodwa okwesikhashana. Ukubeka izingilazi ze-pinhole kunganciphisa inani lokukhanya elingena kubafundi bakho. Lokhu kunciphisa umkhakha walokho odokotela abakubiza ngokuthi “isiyingi sokufiphala” ngemuva kwe-retina yakho. Lokhu kunikeza umbono wakho ukucaciseleka okwengeziwe lapho unezibuko.

Abanye abantu bacabanga ukuthi ukugqoka izingilazi zephinikhodi isikhathi esethiwe usuku ngalunye kungathuthukisa umbono wakho jikelele ngokuhamba kwesikhathi, ikakhulukazi uma ubona kude noma ubona kude. Abukho ubufakazi obuqanda ikhanda noma izivivinyo zokwelashwa ezisekela le nkolelo, noma kunjalo.

Izibuko zepinhole ze-astigmatism

Izibuko zepinhole zingasiza abantu abane-astigmatism ukuthi babone kangcono, kodwa kuphela uma bezigqokile.

I-Astigmatism igcina imisebe yokukhanya amehlo akho ayingenayo ekuhlanganeni ngokugxila okuvamile. Izingilazi zephiniphu zinciphisa inani lokukhanya amehlo akho angena kulo. Kodwa izingilazi zepinhole ziphinde zikhawulele ukubona kwakho ngokuvimba ingxenye yesithombe esiphambi kwakho.

Futhi azikwazi ukuhlehlisa i-astigmatism. Umbono wakho uzobuyela emuva kulokho owawuyikho lapho ukhipha izingilazi.

Ukwelashwa kwamehlo okunye nokwasekhaya kwe-myopia

Uma ukhathazekile nge-myopia, indlela ephumelela kunazo zonke yokwenza ngcono umbono wakho ukugqoka izingilazi zikadokotela noma amalensi wokuxhumana. Lezi zinsiza zombono zingaqinisekisa ukuphepha kwakho kanye nokukwazi ukujabulela imisebenzi yansuku zonke.

Kwabanye abantu, ukuhlinzwa nge-laser kuyindlela yokwenza ngcono ukubona kwamehlo. Enye inketho ukuhlinzwa kwe-LASIK. Isusa izicubu ezingxenyeni zangaphakathi ze-cornea yakho ukubumba kabusha iso lakho.

Enye indlela ukuhlinzwa nge-PRK laser. Isusa ezinye izicubu ezingaphandle kwe-cornea.Abantu abanamehlo alinganiselwe ngokweqile bavame ukukufanelekela ukuhlinzwa nge-PRK laser.

Zombili lezi zinhlobo zokuhlinzwa zinamazinga empumelelo ahlukahlukene kakhulu, kuya ngokuthi ngubani owenza ukuhlinzwa nezinto ezinobungozi ezingafani.

I-Orthokeratology ingenye indlela yokwelapha ukungaboni kahle. Le ndlela yokwelashwa ifaka ukugqoka uchungechunge lwamalensi wokuxhumana amise okwenzelwe ukubumba iso lakho ukuze ukwazi ukubona kangcono.

Uma ukubona kwakho kuseduze kuba kubi kakhulu ngenxa yengcindezi, imisipha elawula indlela iso lakho eligxila ngayo ingaba ne-spasms lapho uzizwa ucindezelekile. Ukuzikhandla ekunciphiseni ukucindezeleka nokukhuluma nodokotela mayelana nezisombululo ezingasiza kungasiza lolu hlobo lwe-myopia.

Ezinye izinzuzo zezingilazi ze-pinhole

Izibuko zepinhole zikhangiswa njengendlela yokwehlisa ijwabu lomhlwenga. Kepha kutholakale okuncane ukuthi izingilazi ze-pinhole zingakhuphula i-eyestrain ngokuphawulekayo, ikakhulukazi uma uzama ukufunda ngenkathi uzigqoka. Kudingeka izifundo eziningi ukubona ukuthi izingilazi ze-pinhole zithinta kanjani i-eyestrain.

Uma uhlangabezana nokukhanya okuvela ekusebenzeni phambi kwesikrini usuku lonke, ungacabanga ngokusebenzisa izingilazi ze-pinhole ukunciphisa ukukhanya. Kepha ukuzama ukusebenza, ukufunda, noma ukuthayipha ngenkathi ugqoke izingilazi kungakhathaza futhi kukunikeze ikhanda.

Odokotela bamehlo kwesinye isikhathi basebenzisa izingilazi ze-pinhole njengethuluzi lokuxilonga. Ngokukucela ukuthi ugqoke izibuko futhi ukhulume ngalokho okubonayo, odokotela kwesinye isikhathi banganquma ukuthi unezinhlungu nezinye izimpawu ngenxa yokutheleleka noma ngenxa yokulimala kombono wakho.

Zenzele izingilazi ze-pinhole

Ungazama izingilazi ze-pinhole ekhaya usebenzisa izinto okungenzeka usunayo. Nakhu okudingayo:

• izibuko ezindala ezinamalensi akhishiwe
• ucwecwe lwe-aluminium
• inaliti yokuthunga

Mane umboze ozimele abangenalutho kucwecwe lwe-aluminium. Bese wenza imbobo encane ku-foil lens ngayinye. Sebenzisa irula ukuze uqiniseke ukuthi izimbobo ezimbili ziyalandelana. Ungafaki imbobo ngokusebenzisa ucwecwe lapho unezibuko.

Ukuzivocavoca kwezingilazi ze-Pinhole: Ziyasebenza?

Odokotela bamehlo bayangabaza ngokusebenzisa izibuko zephini ukuzivocavoca amehlo akho. UPatterson uphakathi kwabo.

“Kunesimo esisodwa noma ezimbili ezingajwayelekile kakhulu ezingasizwa kwesinye isikhathi ngokuzivocavoca amehlo. Kodwa lokhu akuhlangene nokunakekelwa kwamehlo okujwayelekile, ”kusho yena. "Abukho ubufakazi obuthembekile noma kuphi obukhombisa ukuthi abantu banganciphisa ukubona kwabo kude noma ukubona kude ngokuzivocavoca umzimba."

Ngamanye amagama, izivivinyo izinkampani ezidayisa izingilazi zezimbotshana ezisekelayo azikwazi ukuzelapha noma zithuthukise unomphela ukubona kwamehlo kwabantu abadala noma izingane.

Izibuko zepinhole zokusitheka kwelanga

Ungalokothi usebenzise izingilazi ze-pinhole ukubheka ilanga ngesikhathi sokusitheka kwelanga. Ungenza iprojektha yakho ye-pinhole, noma kunjalo. Isebenzisa umqondo ofanayo wokugxilisa amehlo akho ngokuvimba ukukhanya okulahlekile ukuze ubuke ngokuphephile ukusitheka kwelanga.

Nakhu ukuthi uyenza kanjani eyodwa:

1. Sika imbobo encane ekugcineni kwebhokisi lezicathulo. Umgodi kufanele ube cishe nge-intshi eyodwa ngaphesheya nangaseduze komphetho webhokisi lezicathulo.
2. Okulandelayo, thinta ucezu lwe-aluminium foil phezu komgodi. Sebenzisa inaliti ukwenza imbobo encane ku-foil uma isivikeleke kahle ebhokisini.
3. Sika isiqeshana sephepha esimhlophe ukuze silingane kalula komunye umkhawulo webhokisi lezicathulo. Yinamathisele ekugcineni kwangaphakathi kwebhokisi lezicathulo. Khumbula ukuthi ukukhanya okuvela emgodini wakho we-aluminium-foil kuzodinga ukushaya lelo phepha elimhlophe ukuze ubone ilanga.
4. Ngakolunye uhlangothi lwebhokisi lezicathulo, dala umgodi omkhulu ngokwanele ukuthi ukwazi ukubuka ngelinye lamehlo akho. Lona umgodi wakho wokubuka.
5. Shintsha ikhava yebhokisi lezicathulo.

Uma sekuyisikhathi sokubuka ukusitheka kwelanga, yima ufulathele ilanga bese uphakamisa ibhokisi lesicathulo phezulu ukuze ucwecwe lwe-aluminium lubheke lapho ilanga likhona. Ukukhanya kuzongena emgodini bese kuveza isithombe “esikrinini” esimhlophe sephepha ngakolunye uhlangothi lwebhokisi.

Ngokubuka leso sithombe nge-pinhole projektha yakho, ungabuka ngokuphepha konke ukusitheka kwelanga ngaphandle kwengozi yokushisa i-retina yakho.

Ukudla okudlela endlini

Izibuko ze-Pinhole zingasetshenziswa njengedivayisi yomtholampilo ukuxilonga izimo ezithile zamehlo. Zingaba futhi izesekeli ezimnandi zokugqoka endlini yakho ngenzuzo eyengeziwe yokuletha izinto ekugxileni okubukhali.

Kodwa izingilazi ze-pinhole zivimba kakhulu insimu yakho yombono ukuthi akufanele igqoke noma yimuphi umsebenzi odinga ukubona kwakho. Lokho kuhlanganisa umsebenzi wasendlini nokushayela. Futhi awavikeli amehlo akho emisebeni yelanga.

Ngenkathi izinkampani zidayisa izingilazi zepinki njengokwelashwa kokubona eduze, odokotela bayavuma ukuthi abukho ubufakazi bezokwelapha obukhombisa ukuthi bayaphumelela kulokhu kusetshenziswa.
