Sure it is airsoft and not real "operating" but it does put them through some good work. I have learned that running different goggles and glasses during airsoft games will show you which ones will fog up under hard use. Also taking a .20g bb at 350-400FPS gives a pretty good idea of just how stout the lenses are.
I will start with the Prowler Deluxe glasses. These have quickly become my favorite (which I didn't expect to happen), they are comfortable and offer better coverage of my face when combined with my smaller face mask. There are no gaps between the mask and the bottom of the lens so I don't have to worry about a bb coming through.
As far as fogging goes, they do tend to fog up when standing still after running through a room. But they do clear out rather easily, and after treating them with some anti fog cream they do much better.
The lens is really tough, it has taken at least 5 direct hits from under ten feet away and there's no sign of damage. I did manage to mar them a bit when I dropped them after a game, but nothing I won't be able to polish out.
Overall they are extremely comfortable, provide stellar protection for my eyes, and like I said before have become my favorite to wear when playing.
Next are the Alpha Goggles.
These have to be some of the most comfortable goggles I have worn, the padding is beyond adequate and the clarity of the lens is amazing. Both the clear and the tinted lenses offer zero distortion.
The lens is extremely tough just like the prowler deluxe, withstanding multiple hits from close range with .20g bb's. The lenses are surprisingly scratch resistant, even after accidentally dropping them on the ground the lens remained unscathed.
As far as fogging goes, the Alpha does a bit better than the prowler but it still fogs up. This is an easy fix when treated with an anti fogging agent.
Overall the Bobster goggles have been some of the best I have come across, and there have been plenty of people asking about them in between games. I have highly recommended them to other players, and will say that if you are looking for some great safety glasses make sure to head over and give Bobster's site a once over cause they might have something you like.
