Overall, they are a worthy choice. Once you pick the perfect pair of goggles for you, being able to easily change the lenses to adapt to all sorts of conditions helps you get a lot more mileage out of them. Fixed lensed goggles lack the versatility that interchangeable ones do not. It’s just too difficult to find a pair of fixed lensed goggles that will serve you all year round, in all conditions.
Using the right lenses is vital to staying safe. Dark lenses on overcast days will make the snow look flat and can easily hide bumps or rollers that can send you off balance, or into other skiers, trees or rocks. By getting interchangeable lenses you can keep the spare lens in your inside coat pocket, protecting the goggle case from being scratched. If a storm rolls in, head to the nearest lodge and swap out the lenses! Interchangeable lenses are an overall great choice.
