👓 Smith Men's Accessories: Optimal Zero Replacement Lens with Mirror Coating Review

Not used yet but fits great, single wall lenses so no worries about fogging. Will be updated after use. Meanwhile 5 stars for quality and packaging.

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. Contrary to 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. Also, unlike at least one rating, it is a double lens. I haven't skied with the lens yet, so I can't comment on how well it

These aren't really forged lenses, but they're durable and you can't beat the price. I really liked the pink hue in the poor light conditions on the mountain. I think they scratch a little easier but get the job done and are compatible with your Chromapop frames.

Generally great. It seems *a little* less transparent than the Smith brand, but I can't say for sure. The only real complaint is that they are a lot harder to focus on than my Smith lenses. I have 4 Smith lenses and this and the others snap into place very easily, but this lens requires some fiddling to get in.

Bought these to replace a scratched Smith I/O lens. Original lenses are clearly marked I/O; When I tried these interchangeable lenses, they didn't fit. The fasteners did not fit.

This is NOT an I/O replacement lens. The tabs don't even match the product description. The protrusions are at the bottom of the lens, not over the nose like in the picture.

Replacement lenses work and protect from the sun as intended. The only complaint I have is that they don't match the color advertised. The lenses are red all over instead of red in the middle and yellow on the edges.
