Replying to Dragon APX Lens Tint

Does anyone know where I can find a chart for Dragon's lens tints, like Oakleys? I have not been able to find a listing of the Transmission % of the different types of Dragon lenses. I'm looking at These:http://www.ebay.com/itm/Dragon-APX-Jet-Green-Ionized-SPARE-LENSE-2012-Snowboard-Ski-Goggles-NEW-BOX-/120823860513?pt=LH_DefaultDomain_2&hash=item1c21a9cd21#ht_2769wt_1344

But I don't know how dark the Green Ionized will be, my eyes are really sensitive on Blue Bird days, and I want to be sure they're dark enough
