VaepPolarized Replacement Lenses for Maui Jim Banyans MJ412 Sunglasses

Good fit, does require finesse for installing. There are small plastic alinement grommets/guides that need to de reused, and in my case a double set of glasses to see them and the screws enough to correctly make the switch..

Lens fit the frame but they are not as thick as the original Maui Jim lenses and feel loose after the lenses were installed. Glasses are also looser on my head than before.

So as others have said, these replacement lenses are a lot thinner than the factory Maui Jim lenses. While they do fit on the glasses and you can screw them in fine, because they are thinner there is a small gap between the lens and the frames. This causes it to flex a bit. While I think they should last over light use for example driving your car, I will be not using these for outdoor activities as I feel like the frames will eventually break. Optics appear fine, though I can't really compare to the previous lenses I had on the frames as they were scratched up. Compared to other pairs of Maui Jims that I have, I think they aren't as clear/crisp...but still decent for the price.
