    Meaning of "worn addition"?

    Since last week Hoya Mystyles arrive specifying the worn addition. Example below. What exactly do these numbers mean? Is the actual addition 2.22, 2.28 or 2.50? I ordered these for a vertex distance of 15mm.

    It will simply be the compensated add based on frame fit values as well as the method of measuring the addition.
