Amalensi okuxhumana aqukethe ama-nanoparticles egolide athuthukisiwe ayisihlungi sokukhanya ukusiza ukulungisa ubumpumputhe bombala obomvu-oluhlaza.
Ubumpumputhe bemibala yisimo lapho amathunzi athile angase abonakale ethulisiwe noma angabonakali - okwenza eminye imisebenzi yansuku zonke ibe nzima.
amalensi anemibala ku-inthanethi
Ngokungafani nezingilazi ezinemibala ezikhona zokungaboni umbala obomvu-oluhlaza okotshani, amalensi enziwe ithimba le-UAE nelase-UK nawo angasetshenziswa ukulungisa ezinye izinkinga zokubona.
Futhi ngenxa yokuthi basebenzisa izinto ezingezona ubuthi, abanazo izinkinga zempilo ezingaba khona ezimakwe amalensi esibonelo angaphambili asebenzisa udayi obomvu.
Kodwa-ke, ucwaningo olulodwa luphakamisa ukuthi ngaphambi kokuba amalensi afinyelele emakethe yezohwebo, adinga ukuhlolwa ezivivinyweni zomtholampilo.
Amalensi okuxhumana akhethekile athuthukisiwe aqukethe ama-nanoparticles egolide nokuhlunga ukukhanya ukusiza ukulungisa ubumpumputhe bombala, imibiko yocwaningo (isithombe sesitoko)
Ucwaningo lwenziwe unjiniyela wemishini u-Ahmed Salih kanye nozakwabo eNyuvesi yaseKhalifa e-Abu Dhabi.
“Ukungakwazi ukubona umbala kuwukuphazamiseka kwamehlo ozalwa nawo okuthinta u-8% wabesilisa no-0.5% wabesifazane,” kuchaza abacwaningi ephepheni labo.
Izinhlobo ezivame kakhulu zalesi sifo ubumpumputhe obubomvu kanye nobumpumputhe obubomvu - ngokuhlangene okwaziwa ngokuthi "ubumpumputhe bombala obomvu-oluhlaza" - lokho, njengoba igama libonisa, kwenza kube nzima kubantu ukuhlukanisa phakathi kokuluhlaza nokubomvu.
"Ngenxa yokuthi alikho ikhambi lalesi sifo, iziguli zikhetha izinto ezigqokwayo ezisiza ukuthuthukisa umbono wombala," kwengeza abacwaningi.
Ngokukhethekile, abantu abanombala obomvu-oluhlaza okotshani obumpumputhe bagqoka izibuko ezibomvu ezenza leyo mibala ibonakale kalula - kodwa lezi zibuko zivame ukuba nkulu futhi azikwazi ukusetshenziselwa ukulungisa ezinye izinkinga zokubona ngesikhathi esifanayo.
Ngenxa yalokhu kulinganiselwa, abacwaningi basanda kuphendukela kumalensi okuxhumana anemibala egqamile.
Ngeshwa, ngenkathi amalensi esibonelo adayiwe aphinki athuthukisa umbono womuntu ogqokile ngokubomvu-okuluhlaza ezivivinyweni zomtholampilo, wonke awudayi, okuholela ekukhathazekeni mayelana nokuphepha nokuqina kwawo.
Ubumpumputhe bemibala yisimo lapho imibala ingase ibonakale ithulisiwe noma kunzima ukuyihlukanisa.Umfanekiso: Izinto ezinombala ezibonwa ngezindlela ezihlukene zokungaboni ngemibala
Esikhundleni salokho, uMnu Saleh nozakwabo baphendukela ezinhlayiyeni ezincane zegolide. Lezi azinabo ubuthi futhi sekungamakhulu eminyaka zisetshenziswa ukukhiqiza "ingilazi ye-cranberry" enombala o rose ngenxa yendlela esakaza ngayo ukukhanya.
Ukwenza amalensi okuxhumana, abacwaningi baxube ama-nanoparticles egolide ku-hydrogel, into ekhethekile eyenziwe ngenethiwekhi yama-polymer axhumene.
Lokhu kukhiqiza ijeli ebomvu ehlunga amaza okukhanya phakathi kwama-nanometers angu-520-580, ingxenye yesibonisi lapho okubomvu nokuluhlaza kugqagqana khona.
Amalensi okuxhumana asebenza kahle kakhulu, kubika abacwaningi, yilawo enziwe ngezinhlayiya zegolide ezinobubanzi obungama-nanometer angu-40 angazange ahlangane noma ahlunge ukukhanya okwengeziwe kunalokho okudingekayo.
UMnu. Salih nozakwabo baphendukela ezinhlayiyeni ezincane zegolide, ezingenabo ubuthi futhi osekungamakhulu eminyaka zisetshenziswa ukukhiqiza 'ingilazi ye-cranberry' enombala orozi, osesithombeni lapha.
Ukwenza ama-contact lens, abacwaningi baxube ama-nanoparticles egolide ku-hydrogel.Lokhu kukhiqiza ijeli enombala oyi-rose ehlunga amaza okukhanya phakathi kwama-nanometers angu-520-580, ingxenye ye-spectrum lapho kuhlangana okubomvu nokuluhlaza.
Amalensi e-nanoparticle egolide nawo anezindawo zokugcina amanzi ezifana namalensi ajwayelekile atholakala ngokwentengiso.
Njengoba ucwaningo lokuqala seluphelile, abacwaningi manje sebebheke ukwenza izivivinyo zomtholampilo ukuze banqume ukunethezeka kwamalensi okuxhumana amasha.
Cishe umuntu oyedwa kwabangu-20 akaboni umbala, isimo esenza umhlaba ube yindawo enesabekayo.
Kunezinhlobo ezine zokungaboni ngemibala, ezaziwa ngokuthi ubumpumputhe obubomvu, ubumpumputhe obuphindiwe, ubumpumputhe obunama-trichromatic, kanye nobumpumputhe bemibala.
Ubumpumputhe obubomvu buhilela ukukhubazeka noma ukungabi khona kwamangqamuzana e-cone ubude begagasi elide ku-retina;lezi zigaxa ze-photoreceptor zinesibopho sokuzwa ukukhanya okubomvu.Ama-Protan akuthola kunzima ukuhlukanisa okubomvu kokuluhlaza, nokuluhlaza okwesibhakabhaka kokuluhlaza.
I-Deuteranopia yisimo lapho izigaxa eziluhlaza ezizwela ukukhanya zingekho ku-retina.Ngenxa yalokho, ama-deutan akuthola kunzima ukuhlukanisa phakathi kokuluhlaza nokubomvu, kanye nokunye okumpunga, okunsomi, nokuluhlaza okwesibhakabhaka. Kanye nobumpumputhe obubomvu, lokhu kungukuthi enye yezindlela ezivame kakhulu zokungaboni umbala.
I-Tritanopia ingamaseli ekhoni angamaza amafushane ku-retina angakutholi nhlobo ukukhanya okuluhlaza okwesibhakabhaka.Abantu abanalolu hlobo lokungaboni kahle kombala oluyivelakancane baphambanisa okuluhlaza okwesibhakabhaka okumpunga, okunsomi okumnyama nokumnyama, okuluhlaza okumaphakathi okuluhlaza okwesibhakabhaka, kanye nowolintshi ngokubomvu.
Abantu abanobumpumputhe obuphelele abakwazi ukubona noma yimuphi umbala nhlobo futhi bangabona umhlaba ngokumnyama nokumhlophe kanye nemithunzi empunga.
amalensi anemibala ku-inthanethi
Izinduku zisebenza ngaphansi kwezimo eziphansi zokukhanya, kuyilapho izigaxa zisebenza emini futhi zinesibopho sombala.Abantu abangaboni umbala banezinkinga ngamaseli e-retinal cone.
