What dose it mean when you wake up and half of your white part of your eye is total red?

If the white part of the eye, or part of it is totally red, like blood red, it's blood. There's a covering over the eye called the conjunctiva. It has lots of vessels in it. The white part doesn't have a lot of vessels, so it's white, really white. There's a space between the eye and the covering layer, the conjunctiva, called the subconjunctival space. If you for some reason bleed into this area, it'll look really bad, but like a bruise, it'll resolve over a week or two. It'll change colors like a subcutaneous bleed or bruise. The color depends on the type of breakdown product the hemoglobin is in. Hemoglobin is red. Verdiglobin is green (think the spanish word for green being Verde). Then it'll turn yellowish, then it'll go away. As long as the colored part, the iris, behind the clear part, the cornea isn't involved, and the vision is clear or normal, it's just a subconjunctival bleed. Yes it can happen again. Yes to the same eye. Yes to the other eye. Sometimes it's an indication that there's systemic disease such as Hypertension, so it's not always just a bleed.
