Google Lens is an image recognition feature that analyzes images to search for more information about them. Now, Google says that over the next few weeks, it will start rolling out Lens to its Image Search "to help you explore and learn more about visual content you find during your searches." If you use Search and come across an image that you want to delve deeper into, press on the Lens icon underneath it.
Googles Lens will analyze the image and show you other photos related to it, even providing you with links to stores where you can purchase an item that you found in Search. And using a finger to draw a circle around part of an image will narrow down your search results even more.
Another new capability called "featured videos" will find relevant clips related to your search topic. It's all part of Google's plan to make "visual content" more helpful to Google Search users.
