We have this question back when Google Lens was introduced as both the app function was the same. Both were designed to identify objects in pictures, but Lens is far smarter thanks to advance machine learning.
The Google Lens may be advanced in every way than the Goggles but the drawback is the Lens app works only on the new and small group of smartphones. While the Goggles runs on all of the smartphones even from back in 2014.
If you’re still interested in the Google Goggles app you can install it from the third party app providers such as APK Mirror.
