Have you looked at JT paintball goggles? Quite a few guys have inserts for them.
One of the responses in that thread stated that paintball goggles should be used as ballistic goggles were not allowed on field. This struck me as an odd and arbitrary statement as I require a prescription, and paintball goggles do not (afaik) have the option to drop in an Rx insert.
ballistic goggles are typically not allowed on paintball fields because they are not paintball rated. that means that a paintball could break and easily enter the goggles and get into your eyes.
