I've been using Oakley Prizm (Prizm Baseball Infield) lenses and want to tell all of you that these are the real deal. They don't darken your view like some lenses and, in fact, they brighten the colors you see while also eliminating glare. I've never worn prescription glasses, but the first time I wore these on the diamond it felt like I was wearing corrective lenses. I use the Half Jacket 2.0 frame with XL sized lenses. I thought it was necessary to give credit where credit is due. If you're in the market for a new pair, I'd give these lenses a shot.
