Izazinzulu ezisuka kwiDyunivesithi yaseStanford ziphuhlise iprototype ye-auto-focusing glasses ethi igxile ngokuzenzekelayo apho umntu ajonge khona. Inokukunceda ukulungisa i-presbyopia, ilahleko ehambelana neminyaka yobudala yombono osondeleyo ojongene nabantu abaneminyaka engama-45 + ubudala. I-Autofocals ibonelela ngesisombululo esisebenzayo nesichanekileyo kuneeglasi zamehlo zendabuko.
Malunga ne-1.2 yeebhiliyoni zabantu kwihlabathi liphela abachatshazelwa yindalo enxulumene nobudala iso imeko ebizwa Presbyopia eqala ukuchaphazela umbono womntu okufutshane malunga neminyaka engama-45. Njengoko sikhula, iilensi zekristallini emehlweni ethu ziyaqina kwaye zilahlekelwe ukunwebeka okufunekayo ukugxila kwizinto ezikufutshane kwaye ngenxa yoko ngenxa ye-presbyopia abantu bayasokola ukujonga izinto ezisondeleyo ekugxininiseni okubukhali. .
ezahlukeneyo iglasi yamehlos kunye neelensi zoqhagamshelwano ziyafumaneka ukuze kulungiswe i-presbyopia kwaye abantu kufuneka baqale ukuzisebenzisa emva kweminyaka engama-40. Iindlela ezikhoyo zisebenzisa izinto ezigxininisiweyo ezigxininisiweyo ukuqikelela umbono onokuthi uthelekiseke nokuba lens yekristale iya kufikelela kwimpilo esempilweni. iso. Nangona kunjalo, ezi ndlela zineengxaki ezininzi. Iindondo zokufunda zesiqhelo zezomntu omnye, kunzima ukuzithwala njengoko kufuneka zisetyenziswe okanye zingasetyenziswa ngokuxhomekeke ekubeni umsebenzisi uya kufunda na. Ezi glasi zamehlo aziloncedo kangako kweminye imisebenzi, umzekelo ukuqhuba. Iilensi eziqhubekayo zemveli zanamhlanje zifuna ukuba umntu onxibayo alungelelanise intloko yakhe ngendlela echanekileyo ukuze akwazi ukugxila ngokucacileyo kwaye oku kulungelelaniswa kuthatha ixesha. Ekubeni kungekho okanye kuncinci kakhulu kugxininiso lwe-peripheral, olu tshintsho olubonakalayo lwenza kube nzima kakhulu kwaye kuphazamise ukuba umntu onxibileyo agxininise ngexesha lemisebenzi yemihla ngemihla. Utyando lukhetho lokunciphisa ukuqina kweelensi kodwa yinkqubo ehlaselayo kwaye ukuthembeka kwayo kwexesha elide akucaci ngokupheleleyo. Ngaloo ndlela, isisombululo esona sifanelekileyo sokulungiswa kwe-presbyopia asikho.
Kuphononongo olutsha olupapashwe ngoJuni 29 ngo Uphuhliso lwezesayensi, izazinzulu zenze inoveli iperi yeglasi zamehlo zovavanyo ezibizwa ngokuba 'autofocals' ukulungiswa kwe-presbyopia. Ii-autofocals ziquka (a) iilensi zolwelo ezilawulwa ngombane (b) ikhamera ebanzi yokujonga ubunzulu bestereo, (c) izinzwa zokubona iliso lebhayinotyhula kunye (d) nesoftware yesiko eqhuba ulwazi. Inkqubo 'ye-autofocal' kwezi glasi zamehlo ilungelelanisa ngokuzenzekelayo amandla agxininisiweyo eelensi zolwelo ngokusekelwe kwigalelo elifunyenwe kwizikhangeli zamehlo. oko kukuthi into ejongwe ngumnxibi. Oku bakwenza ngokulinganisa indlela yendalo 'ye-autofocus' yeliso lomntu elisempilweni. Iilensi ezizaliswe lulwelo kwiiglasi zamehlo zinokunwenwa okanye zinciphe njengoko ummandla wokubona utshintsha. Abenzi boluvo bokukhangela amehlo balatha apho umntu ajonge khona kwaye bamisele umgama ochanekileyo. Okokugqibela, isoftware yesiko eyakhiwe ngabaphandi icubungula idatha yokulandelela iliso kwaye iqinisekisa ukuba iilensi zijonga into ngokugxila okubukhali. Ukujongwa kwakhona kwii-autofocals kubonwa ngokukhawuleza kwaye kuchanekile ngakumbi xa kuthelekiswa nezibuko zamehlo zendabuko.
Abaphandi bavavanya i-autofocals kubantu abangama-56 abane-presbyopia. Kubekho ukuphucuka okuphawulweyo ekusebenzeni komsebenzi obonakalayo kwaye iiglasi zamehlo zomfuziselo omtsha zabekwa kudidi lwabasebenzisi abaninzi njengendlela yolungiso 'ekhethwayo'. Kolunye uphononongo olubandakanya abasebenzisi be-19, i-autofocals ibonise ukuphuculwa kunye nokubona ngcono kunye nokuqonda okuchaseneyo xa kuthelekiswa neendlela eziqhelekileyo ze-presbyopia. Ababhali bajonge ukunciphisa ubungakanani kunye nobunzima beprototype kwaye bayenze ibekhaphukhaphu kwaye isebenziseke kusetyenziso lwemihla ngemihla.
Iprototype yeglasi zamehlo 'autofocals' ezichazwe kuphononongo lwangoku zisebenzisa iilensi ezikhoyo, itekhnoloji ekhoyo yokujonga iliso kwaye yenze isoftware ekwazi ukusetyenzwa ngolwazi kwaye incede ukujonga izinto ezikufutshane ngojoliso olubukhali ngokuchanekileyo nangempumelelo kuneendondo zemveli. I-Autofocals iya kudlala indima ebalulekileyo kufutshane nombono ukulungiswa kwixesha elizayo.
