Millioner af mennesker verden over har f\u00e5et foretaget laseroperation for at korrigere deres syn, men vidste du, at denne operation kun er mulig takket v\u00e6re teknologi, der er udviklet til brug i rummet?<\/p>\n<\/div>\n

Hvis man kigger p\u00e5 et fast punkt, mens man vipper eller ryster p\u00e5 hovedet, holder \u00f8jnene automatisk blikket fast, s\u00e5 man kan se klart, selv n\u00e5r man bev\u00e6ger sig rundt. De fleste arter p\u00e5 Jorden har denne evne, helt tilbage til dinosaurernes tid. Det er et smart trick fra naturens side, som vi slet ikke t\u00e6nker over.<\/p>\n

Bag kulisserne modtager din hjerne konstant signaler fra dit indre \u00f8re. Disse signaler fort\u00e6ller dig, hvilken retning der er hvilken, og hj\u00e6lper dig med at bevare balancen og holde dit syn stabilt. Dette er muligt takket v\u00e6re tyngdekraften, som fort\u00e6ller os, hvilken vej der er nedad.<\/p>\n

Men hvordan klarer astronauterne sig i rummet, hvor der ikke er tyngdekraft? Hvordan fokuserer deres \u00f8jne p\u00e5 en computersk\u00e6rm, n\u00e5r de sv\u00e6ver rundt p\u00e5 Den Internationale Rumstation?<\/p>\n

\"\"<\/figure>\n

For at unders\u00f8ge dette f\u00e6nomen udviklede forskerne et specielt instrument til at m\u00e5le astronauternes \u00f8jenbev\u00e6gelser uden at forstyrre dem. Instrumentet hedder \u2019Eye Tracking Device\u2019. Det er kort sagt en hjelm med et kamera, der tager billeder af astronauternes \u00f8jne og registrerer, hvor de kigger hen.<\/p>\n

Her p\u00e5 Jorden har netop dette \u00f8jenstyringsudstyr givet l\u00e6gerne mulighed for at udf\u00f8re komplicerede laseroperationer p\u00e5 \u00f8jnene, som har forbedret livet for millioner af mennesker!<\/p>\n

Sjovt faktum:<\/b> Rumteknologien har p\u00e5virket vores dagligdag p\u00e5 utallige m\u00e5der. Nogle p\u00e5 store m\u00e5der, som f.eks. muligheden for at sende information rundt om kloden p\u00e5 f\u00e5 sekunder og udviklingen af proteser. Andre p\u00e5 sm\u00e5 m\u00e5der, som f.eks. behagelige indl\u00e6gss\u00e5ler til vores sko og madrasser af memory foam.<\/p>","protected":false},"excerpt":{"rendered":"
