For a tetracurve GP lens, which curves would you expect to see?

Tetracurve GP lenses contain four curvature zones: the base curve sits on the cornea, two intermediate curves provide a smooth transition from center to edge, and a peripheral curve at the edge shapes the edge profile and tear flow. Because of this four-zone design, the configuration you’d expect is the base curve plus two intermediate curves plus a peripheral curve. Designs with three intermediate curves omit a dedicated edge curve, and those with extra edge curves or fewer intermediate zones don’t match the tetracurve structure.
