Iilensi zoqhagamshelwano eziqulathe iinanoparticles zegolide ziphuhlisiwe ezisihluzi sokukhanya ukunceda ukulungisa ubumfama bombala obomvu-luhlaza.
Ubumfama bombala yimeko apho i-shades ethile ingabonakala ithulile okanye ingabonakali - yenza imisebenzi yemihla ngemihla ibe nzima.
iilensi ezinemibala kwi-intanethi
Ngokungafaniyo neeglasi ezinemibala ekhoyo yokungaboni umbala obomvu-luhlaza, iilensi ezenziwe yi-UAE kunye neqela lase-UK nazo zingasetyenziselwa ukulungisa ezinye iingxaki zombono.
Kwaye ngenxa yokuba besebenzisa izinto ezingezizo ityhefu, abanazo iingxaki zempilo ezinokubakho eziphawulwe ziilensi zangaphambili ezazisebenzisa idayi ebomvu.
Nangona kunjalo, uphando oluthile lucebisa ukuba ngaphambi kokuba iilensi zifikelele kwimarike yorhwebo, kufuneka zivavanywe kulingo lwezonyango.
Iilensi zoqhagamshelwano ezikhethekileyo ziye zaphuhliswa eziqulethe iinanoparticles zegolide kunye nokucoca ukukhanya ukunceda ukulungisa ubumfama bombala, iingxelo zophononongo (umfanekiso wesitokhwe)
Uphando lwenziwa yinjineli yoomatshini u-Ahmed Salih kunye noogxa bakhe kwiYunivesithi yaseKhalifa e-Abu Dhabi.
"Ukungakwazi ukubona umbala kukuphazamiseka kwamehlo okuzalwa okuchaphazela i-8% yamadoda kunye ne-0.5% yabasetyhini," abaphandi bachaza kwiphepha labo.
Iindlela eziqhelekileyo zesi sifo zibomvu-iimfama kunye nobomvu-ubumfama - ngokudibeneyo eyaziwa ngokuba "ubumfama bombala obomvu-oluhlaza" - nto leyo, njengoko igama libonisa, yenza kube nzima ukuba abantu bahlule phakathi kohlaza nobomvu.
“Ngenxa yokuba alukho unyango lwesi sifo, izigulana zikhetha izinto ezinxitywayo ezinceda ukukhulisa umbono wombala,” bongeza abaphandi.
Ngokukodwa, abantu abanobumfama bombala obomvu-oluhlaza banxiba iiglasi ezibomvu ezenza loo mibala ibonakale lula - kodwa ezi glasi zihlala zininzi kwaye azinakusetyenziselwa ukulungisa ezinye iingxaki zombono ngaxeshanye.
Ngenxa yolu thintelo, abaphandi basandul’ ukubhenela kwiilensi ezinemibala eqaqambileyo.
Ngelishwa, ngelixa iilensi zeprototype ezipinki ziphucule imbono yomntu oyinxibileyo ngombala obomvu-luhlaza kulingo lwezonyango, zonke ziyishiyile idayi, nto leyo ekhokelela kwiinkxalabo malunga nokhuseleko kunye nokuqina kwazo.
Ubumfama bemibala yimeko apho imibala inokuvela ithulisiwe okanye kunzima ukwahlula omnye komnye.Umfanekiso: Izinto ezinemibala ebonwa ngeendlela ezahlukeneyo zokungaboni ngemibala.
Endaweni yoko, uMnumzana Saleh kunye noogxa bakhe bajike baba ngamasuntswana egolide. Ezi aziyotyhefu kwaye zisetyenzisiwe kangangeenkulungwane ukuvelisa "iglasi ye-cranberry" enombala werose ngenxa yendlela abasasaza ngayo ukukhanya.
Ukwenza iilensi zoqhagamshelwano, abaphandi baxuba i-nanoparticles yegolide kwi-hydrogel, into ekhethekileyo eyenziwe ngenethiwekhi yeepolymers ezinqamlekileyo.
Oku kuvelisa ijeli ebomvu ehluza ubude bamaza okukhanya phakathi kwe-520-580 nanometers, isahlulo sespectrum apho obomvu kunye nohlaza badibana khona.
Iilensi zoqhagamshelwano ezisebenzayo kakhulu, abaphandi bathi, zezo zenziwe ngamasuntswana egolide angama-40-nanometer ububanzi angazange adibane okanye ahluze ukukhanya okungakumbi kunokufuneka.
UMnu. Salih kunye noogxa bakhe bajike baba ngamasuntswana egolide, angeyotyhefu kwaye asetyenziswe kangangeenkulungwane ukuvelisa 'iglasi yecranberry' embala werose, eboniswe apha.
Ukwenza i-contact lens, abaphandi baxuba i-nanoparticles yegolide kwi-hydrogel. Oku kuvelisa i-gel enemibala ebomvu ehluza ukukhanya kwe-wavelengths phakathi kwe-520-580 nanometers, isahlulo se-spectrum apho i-red and green idibana khona.
Iilensi ze-nanoparticle zegolide nazo zineempawu zokugcina amanzi ezifana neelensi eziqhelekileyo ezifumanekayo zorhwebo.
Ngophononongo lwangaphambili olugqityiweyo, abaphandi ngoku bajonge ukuqhuba iimvavanyo zeklinikhi ukumisela intuthuzelo yeelensi zoqhagamshelwano ezintsha.
Malunga nomntu om-1 kwabangama-20 akaboni ngebala, imeko eyenza ihlabathi libe yindawo eyoyikeka ngakumbi.
Kukho iintlobo ezine zokungaboni ngemibala, ezaziwa ngokuba bubumfama obubomvu, ubumfama obuphindiweyo, ubumfama betrichromatic, kunye nobumfama bombala.
Ubumfama obubomvu bubandakanya isiphene okanye ukungabikho kweeseli zekhowuni zobude obude kwiretina;ezi cones photoreceptor zinoxanduva lokuva ukukhanya okubomvu.IiProtans zakufumanisa kunzima ukwahlula umbala obomvu kuluhlaza, noluhlaza okwesibhakabhaka koluhlaza.
I-Deuteranopia yimeko apho iicones eziluhlaza ezingevayo kukukhanya zingekho kwi-retina.Ngenxa yoko, i-deutans inobunzima bokwahlula phakathi kohlaza nobomvu, kwaye ezinye iingwevu, ezimfusa, neziluhlaza-blues.Kunye nobumfama obubomvu, oku ku enye yeendlela eziqhelekileyo zokungaboni ngemibala.
I-Tritanopia ziiseli zekhowuni ezinobude obufutshane kwiretina ezingafumani kukhanya okwesibhakabhaka kwaphela.Abantu abanolu hlobo lunqabe kakhulu lobumfama bombala babhidanisa ublowu okhanyayo nongwevu, omfusa omnyama nomnyama, oluhlaza ophakathi noblowu, kunye noorenji nobomvu.
Abantu abanobumfama obupheleleyo abakwazi ukubona nawuphi na umbala kwaye banokubona kuphela ihlabathi elimnyama namhlophe kunye nemithunzi yegrey.
iilensi ezinemibala kwi-intanethi
Iinduku zisebenza kwiimeko eziphantsi zokukhanya, ngelixa ii-cones zisebenza emini kwaye zinoxanduva lombala.
