my local optician fitted me out- all you really need are SHATTERPROOF LENSES- the ones made from mineral- if you're really paranoid about glass going into the eye, that sort of thing, just get a pair of PROTECTIVE GOGGLES and wear those over your regular glasses- you can get those at a number of companies, like acklands granger, mine safety supply, etc- it's a whole lot CHEAPER than going the presription/shatterproof and provides a better protection in that it butts to your face- with normal glasses, you normally have a gap between the frame and the front of your face- the goggles eliminate that- i've had more than a couple of hot rounds go down there
