Malenzi ekubatika ane goridhe nanoparticles akagadzirwa anosefa mwenje kuti abatsire kugadzirisa tsvuku-yegirini upofu.
Kupofumadza kwemavara mamiriro ekuti mamwe mimvuri angaite seakanyarara kana kusaoneka - zvichiita kuti zvimwe zviitiko zvemazuva ese zviome.

Kusiyana nemagirazi ane tinted ehupofo hweruvara dzvuku-girinhi, malenzi akagadzirwa neUAE neUK timu anogona zvakare kushandiswa kugadzirisa mamwe matambudziko ekuona.
Uye nekuti vanoshandisa zvinhu zvisiri muchetura, havana matambudziko angangove ehutano akaratidzirwa neakapfuura prototype lenzi aishandisa dhayi tsvuku.
Nekudaro, imwe ongororo inoratidza kuti malenzi asati asvika pamusika wekutengesa, anofanirwa kuongororwa mumakiriniki ekuedzwa.

Tsvagiridzo iyi yakaitwa naMechanical engineer Ahmed Salih nevamwe vaaishanda navo kuKhalifa University muAbu Dhabi.
"Kushaikwa kwemavara ekuona kwemavara idambudziko rekuzvarwa reziso rinobata 8% yevarume uye 0.5% yevakadzi," vaongorori vakatsanangura mupepa ravo.
Nzira dzinonyanya kuzivikanwa dzechirwere ichi tsvuku-upofu uye tsvuku-upofu - pamwe chete inozivikanwa se "red-green color blindness" - iyo, sezita rinoratidza, inoita kuti zvive zvakaoma kuti vanhu vaone kusiyana kwegirinhi uye tsvuku.
"Nemhaka yekuti hapana mushonga wechirwere ichi, varwere vanosarudza zvipfeko zvinobatsira kuwedzera maonero eruvara," vaongorori vakawedzera.
Kunyanya, vanhu vane red-green color blindness vanopfeka magirazi matsvuku anoita kuti iwo mavara ave nyore kuona - asi magirazi aya anowanzo hombe uye haagone kushandiswa kugadzirisa mamwe matambudziko ekuona panguva imwe chete.
Nekuda kwezvipimo izvi, vaongorori vachangobva kutendeukira kune chaiwo tinted contact lens.
Nehurombo, nepo malenzi epink-dhayi akavandudza maonero emunhu akapfeka tsvuku-girinhi mumakiriniki ekuyedzwa, vese vakasiya dhayi, zvichikonzera kunetseka nezve kuchengeteka uye kugara kwavo.
Colour blindness (Colour blindness) inyaya yekuti mavara anogona kuoneka akanyarara kana kuti zvakaoma kusiyanisa kubva kune mamwe. Mufananidzo: Zvinhu zvine mavara zvinoonekwa kuburikidza nemhando dzakasiyana dzehupofu hwemavara.
Pane kudaro, Mr Saleh nevamwe vavo vakashandura kuita tunhu tudiki twegoridhe. Izvi hazvina chepfu uye zvakashandiswa kwemazana emakore kugadzira "razi-ruvara rwe "cranberry glass" nekuda kwekuparadzira chiedza.
Kugadzira iwo malenzi, vaongorori vakasanganisa goridhe nanoparticles muhydrogel, chinhu chakakosha chakagadzirwa netiweki yemapolymer akabatanidzwa.
Izvi zvinogadzira gel dzvuku rinosefa chiedza chewavelengths pakati pe520-580 nanometers, chikamu chespectrum panopindirana tsvuku negirinhi.
Iwo anonyanya kushanda malenzi, vaongorori vanoshuma, aive ayo akagadzirwa ne40-nanometer-yakafara zvidimbu zvegoridhe izvo zvisina kuungana kana kusefa mwenje wakawanda kupfuura zvaidiwa.
VaSalih nevamwe vavo vakashandura kuita tutunhu tudiki twegoridhe, tusina chepfu uye hwave kushandiswa kwemazana emakore kugadzira 'girazi reruvara rwe'rose', riri papikicha apa.
Kugadzira macontact lens, vaongorori vakasanganisa goridhe nanoparticles muhydrogel.Izvi zvinogadzira gel-ruvara-ruvara runosefa chiedza chewavelengths pakati pe520-580 nanometers, chikamu cheiyo spectrum inopindirana tsvuku negirinhi.
Goridhe nanoparticle lenses zvakare ine zvivakwa zvekuchengetedza mvura zvakafanana neakajairwa ekutengesa lenzi.
Nekutanga kudzidza kwapera, vaongorori vava kutarisa kuitisa miedzo yekiriniki kuti vaone kunyaradza kwema lenzi matsva.
Anenge munhu mumwe chete muvanhu makumi maviri haana colorblind, mamiriro anoita kuti nyika ive nzvimbo inotyisa.
Kune marudzi mana ehupofu hwemavara, anozivikanwa sered blindness, double blindness, trichromatic blindness, uye color blindness.
Upofu hutsvuku hunosanganisira kukanganisa kana kusavapo kwemasero ekoni yakareba-wavelength mu retina;maphotoreceptor cones aya ane basa rekuona chiedza chitsvuku.MaProtan akaona zvakaoma kusiyanisa dzvuku negirinhi, uye bhuruu kubva kugirinhi.
Deuteranopia imamiriro ekushaikwa kwemavara egirinhi anonzwa chiedza muretina. Nekuda kweizvozvo, deutans vane nguva yakaoma kusiyanisa pakati pegirinhi netsvuku, uye mamwe mapfumbu, epepuru, negirinhi-blues. Pamwe chete nehupofu hutsvuku, izvi imwe yemhando dzakajairika dzekupofumadza kwemavara.
