I just bought a pair of ice polarized 04-153 juliets from an oakley vault ( I just had too)... I already owned a pair that i have on display, but when i campared the two... the lenses from the pair i just bought have a more purplish tint to them than my other ones. Both are in Brand New condition. Whats the deal? I noticed these on the original xmetal rubys also have this... they have a more darkish violet tint than the replacement ruby lenses sold at the Oakley store. Anyone else notice this or why that is?
