How do i get one of my Snapchat lenses back?

To retrieve a lost Snapchat lens, go to the Camera screen and tap on the smiley face icon to access the Lens Carousel. Swipe left until you reach the "Explore" option, where you can find and search for your previously used lenses. If it's still missing, check your "Memories" section or try looking up the lens creator's profile for access. Additionally, you can save your favorite lenses to ensure they remain easily accessible in the future.
