The widest horizontal dimension of the lens opening of a frame is the

  1. Bridge Size

  2. Lens Diameter

  3. A Dimension

  4. Temple Length

The correct answer is: A Dimension

The bridge size, lens diameter, and temple length all refer to different measurements of the frame, but not specifically the widest horizontal dimension of the lens opening. Bridge size is the distance between the lenses, lens diameter is the size of the lenses, and temple length is the length of the arms that go over the ear. The widest horizontal dimension of the lens opening is known as the A dimension and it is not equivalent to any of the other measurements mentioned. Therefore, A (Bridge Size), B (Lens Diameter), and D (Temple Length) are all incorrect choices. The correct choice, C (A Dimension), specifically refers to the width of the lens opening and is the most accurate answer.
