The width of the frame endpiece to endpiece should be approximately equal to the width of which area?

• A. The facial bone structure just above the cheek bones.
• B. The ear canal.
• C. The eyebrow line.
• D. The lips.

Answer: (A)

Frame width from endpiece to endpiece should align with the widest part of the face, which is the facial bone area just above the cheekbones. This area, the zygomatic region, is the natural width reference because it determines how the front of the glasses will sit and balance on the face. Matching the frame to this width helps keep the glasses stable on the nose and evenly positioned over the cheeks. If the frame is wider, it can slide and look unbalanced; if too narrow, it can pinch at the temples. The other areas—the ear canal, eyebrow line, or lips—do not represent the overall width of the face and won’t give the best fit.
