Miljonid inimesed \u00fcle maailma on l\u00e4binud laseroperatsiooni n\u00e4gemise parandamiseks, kuid kas teadsite, et see operatsioon on v\u00f5imalik ainult t\u00e4nu kosmoses kasutamiseks v\u00e4lja t\u00f6\u00f6tatud tehnoloogiale?<\/p>\n<\/div>\n

Kui vaatad kindlat punkti, samal ajal pead kallutades v\u00f5i raputades, p\u00fcsivad su silmad automaatselt paigal, mis v\u00f5imaldab sul selgelt n\u00e4ha isegi liikudes. Enamikul Maa liikidel on see v\u00f5ime, mis ulatub tagasi isegi dinosauruste ajani. See on looduse nutikas trikk, mille peale me isegi ei m\u00f5tle.<\/p>\n

K\u00f5rvalvaatajale j\u00e4\u00e4b m\u00e4rkamatuks, et su aju saab sisek\u00f5rvast pidevalt signaale. Need signaalid annavad sulle teada, milline suund on milline, aidates sul tasakaalu hoida ja n\u00e4gemist stabiilsena hoida. See on v\u00f5imalik t\u00e4nu gravitatsioonile, mis n\u00e4itab meile, milline suund on allapoole.<\/p>\n

Aga kuidas astronaudid hakkama saavad kosmoses, kus gravitatsiooni pole? Kuidas suudavad nad oma silmad arvutiekraanile fokuseerida, kui nad h\u00f5ljuvad Rahvusvahelises Kosmosejaamas?<\/p>\n

\"\"<\/figure>\n

Selle n\u00e4htuse uurimiseks l\u00f5id teadlased spetsiaalse seadme, millega saab m\u00f5\u00f5ta astronautide silmaliigutusi neid segamata. Seadet nimetatakse silma j\u00e4lgimisseadmeks. Tegemist on p\u00f5him\u00f5tteliselt kiivriga, millele on paigaldatud kaamera, mis pildistab astronautide silmi ja salvestab, kuhu nad vaatavad.<\/p>\n

Siin Maal on seesama silma j\u00e4lgimisseade andnud arstidele v\u00f5imaluse teha keerukaid laser-silmaoperatsioone, mis on parandanud miljonite inimeste elukvaliteeti!<\/p>\n

Huvitav fakt:<\/b> Kosmosetehnoloogia on m\u00f5jutanud meie igap\u00e4evaelu v\u00e4ga paljudel viisidel. M\u00f5ned neist on suured, nagu v\u00f5imalus saata teavet \u00fcle kogu maailma sekundite jooksul ja proteeside loomine. M\u00f5ned on v\u00e4ikesed, nagu mugavad jalatsite sisetallad ja m\u00e4lumadratsid.<\/p>","protected":false},"excerpt":{"rendered":"
