What does the Oxygen Permeability of contact lenses mean?

Oxygen Permeability indicates the amount of oxygen that can pass through a contact lens.

Dk represents the oxygen permeability coefficient, with higher values indicating greater oxygen transmission.
Dk/L is a value obtained by dividing the Dk value by the thickness of the contact lens, representing its oxygen permeability.
A higher Dk/L number indicates a greater ability for oxygen to pass through the lens.
Ensuring adequate oxygen distribution to the cornea is essential for maintaining healthy eyes, making the oxygen transmission rate a crucial criterion.
