The mechanism of eye bags

When we use our eyes too much, we could get eye bags. What is the mechanism? The following is my guess.

When we increase the use of eyes, blood flow to the eyes increases to accommodate the increased energy requirements. If the outflow of blood is not fast enough, liquid accumulates around eyes. That is how eye bags form.

This is a very simple mechanism. But somehow, it takes me quite long to figure it out.

To prevent eye bags, we can try to improve our blood flow. If that doesn’t happen, we should reduce our usage of eyes.
