<prompt> Pfupisa nyaya yacho: Ziso romunhu rakagadzirirwa kuva nokuona kwakanaka kwemavara masikati uye kunzwa kwakakwirira usiku. Asi kutozosvikira nguva pfupi yapfuura zvaiita sokuti masero ari muretina akanga akabatanidzwa nenzira isiri iyo, chiedza chichipfuura nepakati pemasero etsinga asati asvika pamasero etsvimbo nemakoni anoona chiedza. Kutsvakurudza kutsva kwakaratidzwa pamusangano weAmerican Physical Society kwakafumura basa rinoshamisa rinovandudza chiono nokuda kweichi chimiro chinokatyamadza. Vanzveri veIsrael Institute of Technology vakadzidza retinas yomunhu mufananidzo womukati meziso unoratidzwa. Vakaongorora kuti nei masero ari mumarenetina edu akabatanidzwa zvisina kururama. Chiedza chinopfuura nomumusana wetsinga dzetsinga chisati chasvika kumashure. Kutsvakurudza kunoratidzira kuti chimiro chinoratidzika kuva chinovandudza chiono chedu. Makore anenge zana apfuura, vanhu vakawana kuti retina yakanyatsogadzirwa sei. Retina chikamu cheziso chinonzwisisa chiedza, chinofukidza mukati mebhora reziso. Musana weretina mune makoni anonzwisisa ruvara rutsvuku, rwegirini nerwebhuruu. Pakati pemakoni pane tsvimbo, idzo dzinonzwa chiedza zvikuru kupfuura makoni, asi idzo dzisingaoni mavara. Usati wasvika pamakoni netsvimbo, chiedza chinofanira kuyambuka ukobvu hwose hweretina, nematanho ayo etsinga dzetsinga nenyuchi dzesero. Masero etsinga aya anogadzira mashoko emifananidzo uye anoatumira kuuropi, asi kusvikira nguva pfupi yapfuura hazvina kujeka kuti nei masero aya ari pamberi pemakoni netsvimbo, kwete shure kwadzo. Ziso romunhu rinogona kuona zvakawanda kupfuura zvataifunga, vakadaro vanzveri muna December. Pakutanga zvaifungidzirwa kuti ziso romunhu harigoni kuona chiedza cheinfrared, nenzira imwe cheteyo yatisingagoni kuona X-Rays namasaisai eredhiyo. Zvisinei, vanzveri vakazivisa kuti mumamiriro ezvinhu akati, retina inogona kunzwa chiedza cheinfrared pashure pezvose. Chikwata chenyika dzakawanda chevanzveri chinotungamirirwa pamwe chete nenyanzvi dzesayenzi paWashington University School of Medicine muSt. Louis chakashandisa masero anobva muretinas emakonzo navanhu. Kupfurikidza nokupfura lasers dzine simba dzinobudisa kupomba kwechiedza cheinfrared, vanzveri vakawana kuti apo chiedza chelaser chinopomba nokukurumidza, masero anorangarira chiedza ari muretina...  <response>: Vaongorori vepaIsrael Institute of Technology vakadzidza ma retina evanhu. Vakaongorora kuti nei masero ari mumareneti edu akabatanidzwa zvisina kururama. Chiedza chinopfuura nomumusana wetsinga dzetsinga chisati chasvika kumashure Kutsvakurudza kunoratidzira kuti chimiro chinoratidzika kuva chinovandudza chiono chedu.
