Magnetic ski goggles have interchangeable lenses, which are one of the cheapest ways to own polychromatic lenses. This can be considered an advantage as you can switch the color of the lenses according to the color of your dress. If you have an extra lens, it’s useful not only for visual appearance, but also for weather applications. Having extra lenses is a great way to reduce the fog that might build up in your mechanical lenses one day on the slopes, and you won’t have the chance to replace them. With top-of-the-line magnetic ski goggle models, you’re sure to be able to replace them.
