El Ojo y la Vision

Partes del ojo

¿Qué es el Iris? Es la zona circular de color que hay en la parte delantera del ojo. Es un músculo con un orificio central que se abre y se cierra para regular cuánta luz entra al ojo.
¿Qué es la pupila? Es el orificio del centro del iris. La luz entra por ella.
¿Qué es el cristalino? Es la parte que atraviesa la luz que entra por la pupila hasta llegar al interior del ojo donde se forman las imágenes.
¿Qué es la retina? Reviste el fondo del ojo y transforma las imágenes en señales que envía al cerebro.
¿Qué es el nervio óptico? Es el nervio por el que la retina envía las señales al cerebro.
¿Qué recibe el cerebro? Recibe señales del ojo y hace que las sintamos como colores, formas, tamaños y distancias.
