Blas Royo:
    This additional to the frame price rice quoted on line? Correct?  And how would you order as the web page doesn't seem to offer a place to indicate Hi index lenses are preferred?
Linda:
    These quotes are for lenses and are added to the frame price at the checkout.. In the shopping card on the left of the item's description click the button "Add Prescription", then make a choice for the Progressive Lenses and scroll down to see all options available
Blas Royo:
    Thank you.
Linda:
    you are welcome. May I help you with anything else?
Blas Royo:
    No, that would be all.
Linda:
    Have a nice day and bye-bye!
