Light from a source (the sun, or a lamp) is reflected from objects into the eye. The lens focuses an image on the retina. Specialized cells in the retina detect the light, and send signals to the visual cortex at the back of the brain, where the signals from the two eyes are combined. Further processing is done by the brain by processes which are not yet well understood.

Here's a really good website that explains it for you. The site is written for kids, so it may be simpler than you need, but I often use kids' information to get the basics.
