What is the Frequency 55 aspheric dk t? is that sufficient for dry eyes?


Hi Graham, the oxygen permeability of Frequency 55 Aspheric is 19 dk t. For many wearers, this is a perfectly acceptable level, however if you would like a higher level of oxygen permeability, you can try Avaira, which is 46 dk t. You can read more about Avaira here, and we do recommend consulting your optician before switching brands.
