yea its a risk. but being a very sweaty guy the chances of damage are far greater of me not being able to see, adjusting /trying to clean and actually getting shot in eye/doing something properly stupid like running into a wall/tripping etc. and glasses which may well have improved circulation offer no protection from certain angles so i could be screwed if lying down and getting shot from an angle, grenade firing bbs up under the mask etc... ill take mesh thank you...
