|Oxygen permeability (Dk/t)|
It indicates the amount of oxygen which passes through the lens. The oxygen permeability is an key indicator of the lens material. It determines how much oxygen (which is necessary for proper performance) receives a cornea of our eyes. The higher the value, the better. Dk/t is common used and it states: the Dk per thickness of the lens. Usually for a lens at -3.00D, which makes it easier to compare different lenses brands. Ranges from 10-20 Dk/t to over 170 Dk/t.
