Energy, just pure energy.
Massless quanta of photons with zero electrical field.
It is received by your light receptors and the energy is then converted to electrical signals which then travel to your brain which translates this data to the image you see - in living color, no less.
Pretty cool, eh?

When the photons hit a particle, it excited the electrons above their ground state and as they return to ground state they reflect the light. Visible light is just the de-excitation of the atoms releasing light. Make sense?

The nerve impulses caused by the light hitting the light receptors in the eye.....(I don't know the specific mechanisms involved.)

"We look at it" means the photons or waves are passing through our eye and falls on the cones and rods in the retina of our eye.
It is peceived by the brain through the optical nerves as what we see.

Light is just energy. It has no mass (at least not in forms of matter).

You can't really see light but only the objects it shines on thanks to the mechanism Mike J explained.
