The EyeQue PDCheck Frames look too small for me, will they fit?

The EyeQue PDCheck Frames use a spring hinge, also known as a flex hinge, on the frames instead of your standard hinge.  These hinges are equipped with a small spring that affords the arms a greater range of movement and does not limit them to the traditional, 90-degree angle.  This means that it should fit most head types without the need to adjust them to your head type.
