Which modulus is associated with better corneal draping?

Explanation:
Lower modulus means the lens material is softer and more flexible. When a lens can bend and contour easily, it hugs the corneal surface and tears film more evenly, giving better draping. A stiffer, high-modulus lens resists bending, so it sits more on top of the cornea and doesn’t conform as well, leading to poorer draping. So, the softer, low-modulus material is associated with better corneal draping.
