I recently received my Predrox Crystal Clear Flak Jacket XLJ replacement lenses for my Oakley OO9009 sunglasses and I have to say I am impressed with the clarity of these lenses. As a glasses wearer, I appreciate being able to see clearly even in bright sunlight. The lenses also offer excellent UV protection, a must for those who spend long hours outdoors. The only downside is that I had to fiddle around a bit to get the lenses to fit the Oakleys. But once I get the hang of it, they're tight and secure. While replacement lenses can be a bit pricey, the quality of the Predrox Crystal Clear Flak Jacket XLJ lenses is worth the investment. All in all, if you are looking for replacement lenses for your Oakley Sunglass OO9009 glasses, the Predrox Crystal Clear Flak Jacket XLJ lenses are definitely worth considering. They may take a bit of patience to install, but once they're in place, you've got your first line of protection for your peeps.
