Two Doors, One Way Out

You are trapped in a room in broad daylight having two connecting doors, one on each side of the room. One door opens to a fire breathing dragon that will burn anything that enters his room. The other door opens to a room with magnifying glasses pointing in every direction and the sunlight will burn you through the magnifying glasses. How do you get out?

The Answer to the Riddle

Wait until night and leave through the room full of magnifying glasses.
