It's easy to replace the lens on these goggles - BlackHawk Spec Ops Tactical Goggles Clear Lens Replacement

I bought the Smoke lens to replace the Clear lens on the Spec Ops Tactical Goggles. The locking points (little U-shaped cuts) on the replacement lens helped me tell where I needed to pop the current one off. With a little coaxing the lens popped out and the new one was easy to pop right in.
Pros: Pops right in
Cons: A little tricky to pop out the lens already in the goggles
