Google announced last Monday that Google Lens, an application that uses artificial intelligence to detect objects using a phone camera, will be available to all Google Photos users on Android.
Let's say before the Google Lens was available only for the Pixel series.
So the wider Google Lens support started to roll out gradually and if you don't already see it information you should see her in the next few days, according to one Google tweet. 
During MWC in February, Google first introduced the Lens application, which can scan a business card and convert it into contact with the device.
Google's goal for Lens is to understand what you're seeing and take action based on this information. For example, you can start the Google Photos app and place your phone in front of a flower to find out what kind of flower is.
Or you could put your phone in a restaurant and get more information, such as hours of operation.
Google said support would be coming "soon" to the iOS version of Google Photos, but gave no specific details.
Google Photos for Android is available through Google Play. However, on non-Pixel devices, Google Lens will lack Google support Assistant.
