Which statement best describes an optical/cosmetic benefit of aspheric lenses?

• A. Increases frame width
• B. Requires larger frames
• C. Good, tight fit in frame
• D. Reduces frame stability

Answer: (C)

Aspheric lenses change the curvature from the center to the edge, making the edges thinner and flatter and reducing peripheral magnification and distortion. That thinner edge allows the lens to sit more discreetly behind the frame, so frames can be smaller and the overall appearance is more natural. The result is a good, tight fit in the frame, which is a clear cosmetic and comfort benefit. They don’t inherently require larger frames, increase frame width, or reduce frame stability—their main advantage is improved fit and aesthetics due to thinner, more uniform edges.
