there is an element of danger from the view of masks, but you dont need to worry, they should be able to take a direct blow to the lense for close distance without causing you any discomfort (apart from a clean pair of duds), obviously after this they would have to be replaced, but just giving worst senario. If you want advice on what to get, i would advise any of the spectra range from JT, ive got the Flex 7`s and the are sweeettttt!!!!!!! But the new proteus look the poodles noodles.
