why does looking at the sun hurt your eyes but indirectly not so much?

The Short Answer
Ask your best friend to place their mouth directly in front of your right ear hole and say your name loudly. Then, ask them to place their mouth at your left ear and do the same thing–only this time, instead of having their mouth facing directly at your ear hole, have their mouth face the tip of your nose. Which one "hurt" more? The first one, of course. The reason is simple: the pupil of your eye acts exactly like the hole in your ear. It is the tunnel through which the signal (in your ear's case, sound; in your eye's case, light) travels and stimulates your brain. By staring at the sun directly, you are overwhelming your receptors with signal because light is streaming in directly through your pupil–in the same way that your friend's voice felt like it rammed into your right ear. When the light is indirect, you're getting a "sense" of the signal without overwhelming your sensory receptors. Or, in the case of your ear, you're hearing the sound without feeling like someone jammed a Q-tip into it.
