Black spots on my sclera

I have noticed that recently black spots have develeped on the whites of my eyes.  They seem to be at the the ends of blood vessels which appear redder than other vessels in my eyes.  Also, I've noticed that there are patches on the whites of my eyes which appear dark, not yellow, not brown, they just look dirty - maybe  a light beige.  
I can only see this when I hold up my eye lid and look down.  The black specks have only appeared in the last few weeks, but the dark patches have been gradually getting bigger over a period of two years.  Can you please advise if this is anything to be concerned about?

Only a eye exam by an ophthalmologist can tell you for sure, generally its nothing but changes that occur with age.
