Part of the problem is simply due to bad data from the websites. Just as an example - there's a 2-week contact lens called "Acuvue Oasys". And there's a completely different 1-day contact lens called "Acuvue Oasys 1-Day". Some sites have been bad at writing this properly, so both variants may be called "Acuvue Oasys" (or close to it), and the way to distinguish them is to look at the image to see which actual lens they mean, look at the price etc.
It's true that this could probably also be handled by AI, but in the end, classifying the lenses takes like 1-2% of the time it takes to make a scraper for a website so I found it was not worth trying to build a very good LLM classifier for this.
