The presentation of a new technic instrument or appliance or of a modification of a standard type of instrument or appliance should be withheld until the value of the innovation has been proved.

The bands in general use do not fit the curvature of the head; in front the band rests principally on the lower segment because of the weight of the mirror. This does not favor the firm fixation of the mirror or comfort to the wearer during prolonged use.
