Both the smoke and clear lenses are easy to see through. Just bear in mind you will have a slight blue tinge with the blue lens.
Both have a few scratches and normal wear and tear on them. The actual masks themselves however are good. They would just benefit from a good going over with some warm soapy to give them a clean. Take the lens out if you do this to avoid getting water in between the two layers of the lens. i3s come apart quite easily and clean up well.
As per usual, there is a little bit of fading on the contrast colours on the masks but nothing you would really notice unless you are very picky.
Basically, generally pretty good although might benefit from a new lens at some point in the not too distant future.
