Ok, so soon i will be attending phase 1 and at some point i will be doing NBC practice or whatever its current name is. I was told that this entailed passing through a room filled with CS gas in the full NBC gear, which if not properly fitted will cause the wearers eyes to start welling up and suffer a burning sensation. Now i was just wondering if anyone knew what the deal with wearing contact lenses is with this? .i.e the minor degree of common sense i am blessed with tells me wearing contacts whilst suffering inflamation and rawness in your eyes might just be a bad idea. Doe's this pose a risk of eye damage if contacts are worn whilst taking part in this 'exercise'? Are people advised not to wear them during? If so, should i leave the contacts out for a period of time after said activity? I did a few searches with the key words NBC, CS gas, eyes, nothing of relivence arose. Thankyou.
