Figure out source: May just be prominent surface vessels. Maybe be irritation and reactive hyperemia (tired, dryness, environmental irritation, eyedrop preservatives, etc). See if the eyes blanch with visine (not recommended for repeated usage) after having them checked out by an eye care specialist first to make sure no ocular pathology.
