Despre ochi
pagina realizata de Edwald



Omul clipeste o data sau de doua ori la 10 secunde.

O clipire dureaza o treime de secunda. Asta Ónseamna ca in timpul unei zile de de 12 ore, clipim 25 de minute.

Copiii clipesc doar de la varsta de 6 luni.

Morcovul amelioreaza vederea de noapte, pentru ca bastonasele utilizeaza vitamina A din morcov, in fotoreceptie. Varza si alte legume verzi au deasemenea un rol benefic prevenind unele boli ale ochiului.

Ochiul este capabil sa diferentieze aproximativ 10 milioane de nuante dar nu vede lumina ultravioleta.

Insectele pot vedea si razele ultraviolete.
