There is blood in the eyes because there are blood vessels in the eyes, and when you don't sleep well, the blood vessels become congested, and the blood will be worse than usual. Of course some people are born with thicker blood vessels in their eyes than others.

The blood vessels can also rupture when the eyes are overworked or infected, causing bleeding.

1. Getting enough sleep will help moisturize your eyes and reduce the amount of blood in them

2. Clean your eyelids so that they don't become inflamed and covered in blood due to debris, oil, bacteria, makeup and other dust particles

3. Use artificial tears to reduce dryness

4. Apply a cold washcloth to your eyes to constrict the blood vessels and moisturize your eyes
