With the damage to my eye, I need a pair of the Darkest lenses that Oakley makes for my Flak Jacket XLJ's. I am getting a pair of Flak Jacket Deep Water Polarized PRIZM THIS WEEK. I think that they're at 10%, and thatk's pretty close I know. Is there any sense in trying to get 1or 2% darker when I already have a pair of Cebe 4000 Mineral lenses that get me to 8%? Since Oakley doesn't go to 8%, should I just sit tight with the Deep Water PRIZMS? Just asking for a few edumacated opinions.
