Pressurized commercial aircraft have two or more layers of air-tight lexan to keep the aircraft pressurized, and have an additional layer on the inside to protect the lexan from damage. As the aircraft changes pressure, the small hole allows air to vent in and out for pressure equalization between the layers of window. The hole is between the outer layer and the aircraft cabin, but is not connected to the air outside the aircraft.
