Minus lenses with plus carriers in GP lenses result in edges being:

• A. Edges thicker; sit higher
• B. Edges thinner; sit lower
• C. Edges thinner; sit higher
• D. Edges thicker; sit lower

Answer: (B)

In GP lenses, how thick the edge is and how high it sits compared with the center comes from how the lens distributes sagittal height from center to edge. When you pair a minus power with a plus carrier, you shift more of the thickness into the central optical zone and reduce the peripheral bulge. That redistribution makes the edge thinner and lowers its effective height on the eye. The edge doesn’t rise as much and sits closer to the tear surface, which is why the correct description is edges that are thinner and sit lower.
