Don't confuse _______ measurement with where the nose contacts the frame.

Explanation:
DBL stands for Distance Between Lenses, the horizontal distance between the centers of the lenses. It describes how far apart the lenses are, not where the frame rests on the nose. The part that contacts the nose is the bridge width (bridge measurement). So the statement cautions not to confuse the DBL with the nose-contact area. The other terms don’t denote this specific lens-to-lens spacing.
