The Boston web site states that their Boston 7 lens "utilizes
innovative technological innovations in basic polymer chemistry to
achieve a lens that offers a balance between the effects of low and
high dk materials."
What are these effects that their lens balances? |

The higher the dk, the higher the oxygen permeability of the lenses. So, one
would think that higher dk = better. So, I'm not sure why they advertise
"offers a balance between low and high dk". |
