NOLA IKUSTEN DUGU?

 Argia objetuetan islatzen ( erreflejatzen) da eta hori gure begietara
 iristen da.
1.     Irudia ( argia behar dugu ikusteko) korneatik pasatzen da.
2.     Irisa handitu/ txikitu egiten da argi gehiegi/gutxiegi sar ez dadin
       eta ikusmen bikaina izateko.
3.     Irudiak begi ninia zeharkatzen du eta kristalinoa ere bai.Irudia
       fokatzen dugu.
4.     Irudia erretinara iristen da eta horren zelulek, ikusmen nerbioaren
       bidez antzematen dutena bidaltzen diote burmuinari.
5.     Burmuinak informazio jaso eta interpretatzen du, ikusten ari
       garena zer den jakiteko.
