Google announced its revolutionary Google Lens feature in May 2017. This feature employs machine learning and image recognition to recognize objects and scenes. According to some posts by some Reddit users, the feature now seems to be rolling out to the Pixel 2 and Pixel 2 XL phones.

Earlier, users who rooted their Android devices were able to enable Google Lens feature in the Assistant app. However, now Google seems to have started the official rollout of the feature. The tech giant has not made the announcement regarding the deployment yet. For the Pixel 2 and Pixel 2 XL users, the latest update brings the Lens in Assistant, which means that they can now check the feature with the Assistant.
