Simply put, the form fitting might work on some facial configurations but didn't work on mine. Light seaped in easily and, because it was form fitted, there was nothing I could do. The earplugs are a joke. They are made of some sort of spongey material that resembles packing peanuts. Not only do they not block sound, they were mal-shaped after trying them on.A total waste of money.
