Snapchat regularly updates its lenses and features, and the way to unlock specific lenses may vary over time. As of my last update, you can unlock lenses in Snapchat through several methods:
1. Lens Carousel
Open the Snapchat camera and access the lens carousel by tapping and holding on your face on the screen. Swipe through the available lenses until you find the butterflies lens. It might be located among the popular or recently added lenses.
2. Scan Snapcode
If someone has shared a Snapcode (a special QR code) for the butterflies lens, you can unlock it by scanning the Snapcode. To do this, open the Snapchat camera, point it at the Snapcode, and press and hold on the screen until Snapchat recognizes the code and activates the lens.
3. Lens Sharing
If one of your friends sends you a snap with the butterflies lens applied, you can swipe up on the snap to access and use the lens yourself.
4. Lens Challenges
Snapchat occasionally runs special lens challenges or events. Participating in these challenges may unlock specific lenses, including the butterflies lens.
5. Lens Store
Check the Lens Store within Snapchat to see if the butterflies lens is available for download. Sometimes, you can find additional lenses that you can download and use from the Lens Store.
Please note that these methods are based on information available up until September 2021, and Snapchat’s interface and features may have changed since then. If you are unable to find the butterflies lens using these methods, consider exploring the Snapchat app or its official website for the latest information on lens availability and unlocking methods.
