I bought these Wiley X goggles retail to try them out for workers at about $130.  They don't suit all shapes of faces and the lenses with optical correction are not rated Vo (can't use them as safety glasses at work). 

Wiley did not provide info on the ratings so I could not use them and ended up with ESS ICE glasses which are also NSNed and a lot less expensive.  The Rx insert for the ESS ICE glasses is great for people with corrective lenses.

ESS V12 goggles as used by British forces have better rating (V50) than Wiley X and also have Rx inserts for people needing corrective lenses.

ESS NVG goggles ar the go for people in seriously bad conditions, they also use Rx inserts if you need corrective lenses.

Don't waste good money on Wiley X stuff unless its just to go surfing.
