Does Hubble Contacts have an llms.txt?

About Hubble Contacts

Founded 2016 · US

Jesse Horwitz and Ben Cogan founded Hubble after noticing that daily contact lenses were sold via insurance + optometrists at 5x the cost of equivalent products. The subscription model — $30/month for daily lenses — was novel for the optical category. Hubble has weathered FTC scrutiny over prescription-verification practices but remains a category leader.

Notable for the llms.txt validator

Hubble was one of the first DTC subscription brands at scale in a regulated category. The stack reflects subscription billing maturity (Recharge-class apps) + medical-content compliance signals.

No llms.txt detected

Hubble Contacts hasn't published a /llms.txt yet. ChatGPT Shopping, Perplexity Buy and Google AI Overviews can still index the store via inference, but the merchant has no control over which pages get prioritised. A spec-compliant llms.txt fixes that — BrandUp Factory's Index AI app generates one automatically from any Shopify catalogue.

What this AI-search readiness signals

Hubble Contacts doesn't currently publish /llms.txt. AI engines (ChatGPT Shopping, Perplexity Buy, Google AI Overviews, Claude) can still index the store by inference but the brand has no explicit control over which pages get prioritised. At Hubble Contacts's scale + brand recognition, the upside of shipping an llms.txt is real — these engines already mention the brand, the question is whether the surfaced details are the ones the brand would choose.

Cross-check with the Schema Audit — high-grade structured data + a clean llms.txt are the two pillars of AI-search visibility. Brands that win one tend to win the other.
