As the modulus of elasticity increases, soft contact lens rigidity does what?

Explanation:
Modulus of elasticity is a measure of stiffness: the higher the modulus, the stiffer the material. For soft contact lenses, a higher modulus means the lens resists bending and deformation more, so its rigidity increases. Conversely, a lower modulus makes the lens more flexible.
