I Woke Up And Went Down Stairs At 2 Am.

I woke up and went down stairs at 2 am. I could not see a spot on the left side in both eyes. It is getting better now. and outer left side has an aura and it is not as visible now. My left eye is watering a little bit. Do I have to worry about anything or do you think it just might be from darkness to light. I do have dry eyes so that could be the cause of the watering.
