ESS
If you're looking for good eye protection at a reasonable price, and not a fashion logo, take a look at ESS - Eye Safety Systems. Their googles are now a mandatory issue item for US forces in Iraq. They make an eyeshield sunglass called the ICE that uses the same insert as the goggles for RX applications, and offers the same ballistic protection as the goggles. Since it's an insert it can handle prescriptions of either +/- 6 or +/- 12 depending on the insert frame. I cant remember if the plastic insert or the metal wire one handles the greater range. US forces use the plasstic insert and the Brits use the metal wire one. I'm very happy with the ESS goggles I was issued. The ICE eyeshield can be found for under $30 with 2, if not 3, lenses, and the RX insert is optional for those who need it. Overall my experience is that it's a very good product, and the prices I've seen online for what I was issued seem very reasonable to me.
