No, Snapchat cannot see your eyes only. Snapchat is a mobile app that allows users to send photos and videos to their friends. It does not use any facial recognition technology to detect or track specific features such as eyes. The only way for Snapchat to “see” your eyes is if you take a selfie with the app, which will capture an image of your face including your eyes. However, this image is not used for any kind of tracking or recognition purposes; it’s simply stored on your device and accessible through the app.
