Which blending level allows for easy identification of the junction in a blended GP lens?

Explanation:
In a blended GP lens, the junction is where one curvature transitions to the other. The blending level controls how sharp that transition is. A light blend keeps the boundary relatively crisp, so the point where the central zone ends and the blending zone begins is easy to spot during examination. If the blend is heavier, the transition becomes smoother and the line fades, making the junction harder to identify. So, a light blend best facilitates easy identification of the junction.
