With the base curve expressed in radius (mm), a lower number corresponds to which curvature?

Base curve radius tells how tightly the lens bends to fit the cornea. A smaller radius means a tighter bend, which is a steeper curvature. So, when the base curve is expressed in millimeters, a lower number corresponds to a steeper curvature. A larger radius would be flatter, and “no change” would imply the curvature isn’t affected by the base curve, which isn’t the case. Edge lift is about the edge profile and peripheral fit, not the central curvature defined by the base curve.
