Which statement best describes the purpose of matching frame width to the facial bone structure above the cheek bones?

• A. It ensures the eyes are perfectly centered in the lenses
• B. It keeps undue stress from being placed on the endpieces and hinges of the frame
• C. It makes the frame lighter
• D. It improves cosmetic appearance

Answer: (B)

The frame should sit on the bony areas above the cheek bones so the frame’s weight and forces are borne by solid bone, not soft tissue. When the width matches these cheekbone landmarks, the frame distributes load evenly and minimizes torque on the side connectors. That reduces stress on the endpieces and hinges, helping prevent distortion or breakage over time. While cosmetics or eye centering can be affected by fit, the main purpose is to protect the frame’s mechanical joints by providing stable, balanced support.
