    Noel - correct. Shade 5 is shade 5, no matter what the material. A
    standard shade 5 glass filter must have the same transmission as a
    polycarb filter, or a gold-coated filter for that matter. If Donna
    can see easier through the gold coated filters than she can through a
    standard filter, than the gold coated filter IS NOT a shade 5.
