Add the blueberries and lime to a pitcher.
Muddle the berries and lime with the bottom of a wooden spoon.
Add the tea bags and cover with water.
Cover and refrigerate for 2-4 hours. Taste it after 2 hours and if you want it stronger, let it go longer.
Once it's steeped enough for your liking, remove the tea bags.
The limes can be removed after about 4 hours and the juice squeezed into the iced tea and discarded.
