Review on 🔍 Smith Mirror Zero Replacement Lenses by Auden Paz

This lens is a good replica of the Smith I/O lens. The only difference is that it's missing a tiny hole for moisture trapped between Smith's version's dual lenses. Unlike other reviews, it fits the Smith I/O frame. I/O lenses aren't that easy to change, and even with Smith brand lenses, some are easier to change than others, mainly the tabs on either side of the nose. In addition, contrary to at least one assessment, it is a double lens. I haven't skied with the lens so I can't comment on how well it performs on the slopes. I don't know if the lack of venting is an issue, but I've ridden many different non-vented dual lenses and fogging between the lenses hasn't been a problem. In fact, I had some fogging with Smith vented lenses. This particular lens color is new to me.
