The permeability of a contact lens is denoted by which value?

The correct answer is: DK

The permeability of a contact lens is denoted by the value DK. DK, also known as oxygen permeability, is a critical factor in determining the ability of oxygen to pass through the contact lens material to reach the cornea. Higher DK values indicate better oxygen permeability, which is essential for maintaining the health and integrity of the cornea during contact lens wear. Thus, option C is the correct answer.
