Overall the lenses are good. I bought these for an old pair of Oakleys that I wear to the pool/beach. I have previously bought a pair of Revant glasses for a pair of demi jackets and they were good but not very fitting (a bit narrow/large). As stated in the reviews of these mustache replacement parts, the lens is a bit small. After installing them, I found that they were loose even after tightening the set screws as tight as possible. When adjusting, you can sometimes see a thin streak of light coming through a corner or inward bend. However, as long as you don't vigorously wipe it on your shirt, the lens fits well enough to stay in place. Price was an important factor as I didn't want to destroy a set of Oakley OEM replacement lenses based on my needs. All in all, if you're looking to save money and understand that these lenses are good but not perfect, you'll be fine. If you want perfection I would suggest buying an OEM lens.
