I have a pair of old Oakley OO eyeglasses and I want to put prescription lens on them. Unfortunately, my prescription is very strong, from -8.00 to -8.50 for my right eye, which means I have to use high index lenses. Oakley, however, doesn't tell you the refractive index. They only have 3 different thickness levels with their own branding. How slim are the O Authentics Extra thin?
