I just began having this problem over the last 2 weeks.  My teenagers noticed it first.  I wake up with small, yellowish bruises near the outer edges of my eyes.  Usually just one eye. They go away as the day wears on.  It usually happens 3 to 4 mornings a week.  I have an appointment with my eye doctor to see what could be causing this.  I am experiencing menopause, so hormone changes could be a possiblity.   A cold washcloth with crushed ice helps them fade faster.
