The bevel used most commonly for low power lenses edged to fit into plastic and metal frames is called:

• A. Standard bevel
• B. V bevel
• C. Bead bevel
• D. Standard or V bevel

Answer: (D)

Bevel describes the angled edge added to a lens so it seats properly in the frame. For low-power lenses that are edged to fit into both plastic and metal frames, the most common and versatile options are the standard bevel and the V bevel. The standard bevel provides a gentle, regular edge that fits well in most rims, including metal frames and many plastic frames. The V bevel creates a sharper, V-shaped edge that can help the lens sit securely in plastic frames with a groove or channel. Because both styles are routinely used for this scenario, the option that says standard or V bevel best matches typical practice. Bead bevel is more specialized and not the general choice for this situation.
