Mate, there's a thread on pbn which I put something on yesterday, some pics and vids
believe me the only thing really liable to break are the tabs on the lense, the rest of the plastic is pretty much bomb-proof

I'm not the fastest myself putting it back together & I find the hardest bit starting to fit the lense piece back onto the mouth-guard
It took me roughly 3 1/2 min to take it apart & put it back together back to back,
the sound isn't very clear so I said
"then with this, you get the longer tab, and put that in first: the one at the top, and press it in" and again on other side top one first
Use in conjunction with his (good) instructions:
Though I would add that while none of the soft plastic parts are really breakable, it isn't hard to break the tabs off the lense; so don't be too rough.
1.remove your visor from the goggle frame,if you have it on.
2.grab the goggle frame around each tab and pull it off with minimul force.(It won't tear)
3.Take your goggle frame and lift the rubber part up and off the top where it says DYE.
4 begin moving along to each tab left and right of the first tab pulling
the tabs off,some force may be required,but don't worry you won't rip the goggle frame.
5. now that the top 3 tabs are undun simply take hold of the lense and pry it out. It should come out quite easily now,simply pulling the top of the lense downward will make the tabs pop out of place.
6.Grab your new lense and lightly lube up the tabs around the mask(I recommend using fairy liquid
)
7.Now that you lubed up the tabs,put the left and right sides(the parts with out tabs on them)into the frame first.
8.go around to each tab and with light force slide them into place.
9.next grab your mask(the part that guards your mouth) and lube up each tab that connects to the goggle frame,and lube those tabs as well.
10.line up each tab with it's corresponding hole.
11.place one thumb under the tab and take your other hand and place it on top of the goggle frame push down on the top and push up under the tab. The tab should now slide perfectly and snugly into place.
12.now take the little pieces of rubber that hold the nose part of the goggle frame and slide that into place(this shouldn't require lube but feel free to lube it if you feel the need to)
Keep in my you do not need to fear ripping or tearing your mask or the goggle frame it wont rip or break tabs no matter how hard you push or pull on it
EDIT:this is the same method I use on my Invison and I can do this whole process of changing lenses is in under 5 minutes
Fell free to ask any questions or make any suggestions."
