Google will soon give iOS users the chance to try Google Lens, the technology that lets you use your camera to search for info. Over the next week, you'll be able to try Google Lens in the Google Photos app for iOS, the company announced Thursday. The feature will roll out over the next week. You'll have to have the latest version of Google Photos to access Google Lens. 

Google Lens uses augmented reality to give you information about the things your camera sees. For example, you can point your camera at a flower, and Google Lens will give you info on the type of flower at which you're looking.
