Why does a 5 mW laser damage the eyes more than a 13 W light bulb if the bulb has over 2,000 times the energy?

If you're standing one meter away from the bulb and your eye is one square centimeter, it is getting about 1/100,000th the power of the bulb (consider what fraction of the light hits your eye). If a beam is the size of your eye, and it hits you in the eye, that is 100% of the power delivered to your eye.
