Quoted: Sniper 350,
Impact resistant and scratch resistant are two different things. You don't want them so hard that they don't scratch, as that means they could be brittle and shatter. Polycarbonate impact resistant lens are soft and scratch easily.
So if you are going to protect your impact glasses with a pair of googles, you want those googles to be impact resistant too so you don't get a face full of fragments. Or just pay to get the impact resistant lenses replaced.
I have a couple nice pairs of cebe and julbo frames with impact resistant lenses that I like. I'm with MlTCHELL, they Oakley frames really don't have much to offer.

Again, about the Polycarbonate material. It's absolutely incredible. I have no problem whatsoever trusting my eyes to a lens even as thick as 1mm of polycarbonate. That one paintball mask standing up to repeated hammer blows, over and over as hard as I could, and the thing did nothing other than scratch and fly across the room, that was plenty impressive for me to trust polycarbonate. I reccomend if you know anyone who has any old polycarbonate lenses, or the eye doctor might have some samples or something, ask for a piece. Take it outside and pound on it with a big rock... chances are you won't be able to do anything other than scratch it.
I definitely wouldn't say the Oakley frames don't have much to offer. They do, just not for me. If they're not fitted with a perscription lens, they're great looking glasses that offer great impact protection and many choices of styles and colors. Though, with a perscription installed, they look like ass and they're not as strong, because they basically cut out two big holes in the lens/shield for the perscription lenses, and install them inside the original lens/shield. If you see some, you'll see what I mean. If you ever see anyone wearing M-frames with a perscription lens,
you will know. They look so weird, you'd spot them without even knowing what you were looking for.
Quoted: Contacts are the closest thing to having lasik surgery. You lose so much peripheral vision with prescription glasses that it isn't really useful. You can wear contacts infrequently and wear glasses normally if you're not comfortable. Your vision can change within a year or 2, and your glasses will become obsolete unless you buy new lenses ($$$). You can't get polarized and mirrored prescription lenses cheaply. You can get contacts rather cheaply ($100 for a 1-2 year supply) online and just buy 1 pair of really good shooting glasses. Then when your vision changes, get a new contact prescription and buy 1 or 2 boxes ($20 or so) and wear them infrequently.

Honestly, that's what I thought about the peripheral vision, but with my perscription, that's not the case. I'm lucky. Suposedly, I have a slight astigmatism or something pronounced like that, and I don't think the contacts will work, that and the putting shit in my eye routine creeps me out.
The guy who helps choose lenses at my opthamologist told me the more powerful the perscription, the smaller the "sweet spot" of the lens. Mine, I honestly can see as pretty much everywhere else on the lenses. But then again, my perscription is not very powerful.
