Kungava munhu kaviri mboni?

Hapana chakavanzika zvakawanda zvinoshamisa zvinowanikwa physiology kwevanhu. Uye nhasi kashoma kuti mumwe munhu anogona kushamisika neizvi. Zvinenge sokuti, kwete kare, vanhu vakaungana kubva pamusoro nzvimbo dzakapoteredza kutarisa murume ane munwe pamusoro ruoko rechitanhatu. Hazvishamisi, kana ukaona ichi, "muridzi dzimwe phalanx" muzuva redu, akamira mainjisi mashoma kubva kwamuri, somuenzaniso, vakamirira mumutsetse zvokudya.

Uyewo haazorambi kushamiswa uye peya Siamese pemapatya. Uye kunyange kana vasingagari kuninira iwe kubva pachikuva, asi chete zvake ezvinhu achapfuura. Nokuti ivo vari kare saka promozolili maziso ose pamusoro TV, iyi achasiyiwa pasina kutarisirwa. Uyezve, mune maawa mashoma hapana uchayeuka kuti munguva ichangopfuura akafamba apfuura payo vaviri adherent mumwe vanhu.

Asi chii kana apo tichifamba iwe kubata meso pamusoro pake haana mbiri, asi mana vadzidzi? Uye mumwe yeziso wavo uchava maviri. Dual mboni - iri vatova chaizvoizvo kuziva, handizvo here?

Kana chaizvoizvo here?

Zvichida Fani iyi kana kwete, kuti gakava kuitwa nhasi. mushonga Modern zvachose anoramba chokwadi ichi, sezvo chirwere "mboni kaviri". Zvechokwadi, zvinokwanisika kuti pane zvakawanda nyaya umo murwere yeziso anenge akaita mbiri vadzidzi. Asi kazhinji zviri kutyora the retina, kana kukura chisvetasimba, uye zvichingodaro. N.

Zvisinei, Fani iyi Pupula duplex (double-mboni) rinowanikwa zvinyorwa zvakawanda sezvo nyanzvi dzekare uye vanoongorora wekupedzisira remakore.

Wokutanga kutaurwa

Pakutanga, chirwere chainzi "dhiyabhorosi retsono." Magwaro aya anogona kuwanikwa mabasa vanyori vekare. Muenzaniso unoshamisa ndiro basa nomudetembi wechiRoma Ovid, apo miviri mudzidzi ane nzvimbo inokosha. Chokwadi, mumazuva ekare akadaro chinoshamisa chinhu asi chinokatyamadza, asingagoni kuuya vanhu.

Zvisinei, vakabudirira chaizvo vanhu vamire pakati yokuisira yeziso kwakadaro. Mumwe wavo ari Liu Chun - Gavhuna yekare Chinese guta Shanxi.

Taura pamusoro Liu Chun Munhoroondo

Kare kare, muna 995 BC. e., muguta China Shanxi gavhuna akasangana Liu Chun. Gare gare hwakatamisirwa pambiru gurukota State. The mukuru akawana mukurumbira nokuda kwezvikonzero zviviri. Wokutanga - akakwanisa kuti mwanakomana wake mugari wenhaka yose China, waimira sezvo ukama dzaro chirikadzi Empress. Chechipiri - Liu Chun akanga vadzidzi vaviri muziso rimwe. Uye mupiro mukuru kuna mukurumbira wake achiri akaita chaizvo pfungwa iyi. Iri Chinese mushumiri ichi anofananidzirwa mumifananidzo, uye anotarisa sezvinoita namo wewakange, riri Ripley kuti London miziyamu. Uye Chikurukuru, kuti uyu sei akanga akabatwa nyaya - ". Murume Dual maziso"

Kuwedzera kune izvi nyaya, hunyambiri ziso ndee mukurapa muna 1931. Mumwe Genri Houn - mugari reKentucky - aiva mudzidzi kaviri. Photos, izvo angadai yasimbiswa Fani iyi, uye haana kupiwa komiti nesayenzi akasiya Va nenzira isingaoneki achitovabatsira kunatsiridza pasina pfungwa.

Studies remakore rechi20

Dual mboni kwakaita yakawanda kufarira pakati masayendisiti munguva kubvira 1902 kusvika muna 1918. Zvakatanga pamwe Kirbi Smita tsvakurudzo, vakazochinja akadzinga Walton Brooks McDaniel basa rake "Double-mboni nezvimwe kuratidzwa wadhiabhori meso."

In basa rake Pupula Duplex Smith anoti pfungwa iyi ane hunhu yokufananidzira, kwete zvokurapa. Uye ichi yekare akataura kusiyana ruvara mune munhu ziso (eg kuruboshwe - zvitema, uye kodzero - green). Uye ichi chinoratidza sayenzi yemazuva anonzi saizvozvo heterochromia.

The kusanzwisisa yekare vanyori Fani iyi anobvumirana Smith uye McDaniel. Asi, maererano shanduro yake, vanhu vomunguva idzodzo anongonzi pupula duplex mananara akadai Somuenzaniso, mudzidzi dilation, retinal zvirwere nezvimwe kuremara ziso. Uye zvirokwazvo vose pamusoro ichokwadi, uye anokwanisa kusika fungidziro miviri mudzidzi.

Vanoti chii pamusoro pazvo nhasi?

Kana ukabvunza mubvunzo ophthalmology ano dzakadai, chete kuseka kunogona kunzwika zvakanaka nyaya. Sayenzi refu kuramba mukana kugara ziso rimwe vadzidzi vaviri.

Kunyange zvakadaro, muna munhoroondo mushonga zvechokwadi nyaya imwe chirwere - Policoro. Izvi hazvina kuvapo maviri kana kupfuura vadzidzi, agglomerated pamwe chete nyore.

Kusiyana nyaya yokutanga (kaviri mboni), Policoro, hosha runoratidzwa kutarisana kusanzwa, kuwedzera pamusoro kutarisana acuity. Kana zviri inoitika kune usimbe kwomusikirwo chiedza muna ziso zvomukati. Zviri anobvisa kuti vanoenda kukireshi zera chete kuvhiyiwa. Kana nzira iri asingaiti nguva kurwara, iye ndishandise kuonana lenses. Asi nezviyero zvose izvi prinimayutisya chete vaya vane vadzidzi vanopfuura vatatu. Uyewo kuti aramu kunogona kuva uye zvavari rakawedzerwa 2 millimeters.

Ngano pamusoro kaviri mboni

On the kaviri mudzidzi, kune vazhinji ngano siyana. Mukuru wavo ndechokuti miviri ziso - chiratidzo radhiabhori. Mumazuva ekare vanhu vakadaro vakanga pasi vanovaseka uye kutambudzwa.

Panewo maonero kuti chipo (mazuva ano kunzi dzine). Ostensibly munhu ane yakadaro chepfungwa ziso anokwanisa kunzwisisa nyika zvakarurama, ichijekesa nechimwe chine maatomu akafanana kuti chinoita kuti chinoshamisa - inenge akakwana. Zvakadaro, vamwe vanoti, uye chirwere "Policoro". Maererano navo, mudzidzi wose ane sphincter kuti anobvumira kuti ishande zvakafanana nevavakidzani. Zvisinei, ichi ari kutsausa. mumwe mudzidzi ari yeziso mune chirwere ichi chete vamakamupa sphincter. Uye nyaya dziri kushanda.
