Using AI to preserve and
extend elite creative expertise
With other tools, collaboration becomes the bottleneck. With Gemini, prompting and iteration are intuitive enough that we can move fast without endless translation.

For more than two decades, Black Eyewear has stood apart in the eyewear world. Founded in London by legendary optician Robert Roope, the small, family-owned British brand is devoted to the heroes of jazz—musicians, artists, and cultural icons whose individuality and confidence are expressed as much through their eyewear as their music. From a small shop to frames now worn by celebrities including Pedro Pascal and Lady Gaga, Black Eyewear has built its reputation on taste, opinion, and deeply personal consultation.
At the center of that reputation is Robert Roope himself. With more than 60 years of experience, he doesn't sell glasses by scrolling through inventories or asking about past purchases. He looks at a customer, listens to them, and makes a judgment—an opinion refined over decades of craft. But as demand grew and commerce shifted online, the brand faced a fundamental challenge: how do you scale something that is, by definition, human and rare?
In 2020, Tomas Roope—Robert's son—began experimenting with whether AI could learn personal taste rather than generic preference.
His early projects involved training small, specialist models on highly curated datasets to see if AI could replicate elite judgment. The insight that emerged became the foundation of a collaboration between Roope and his friend Charles Barlow, with a mission to explore how artificial intelligence could preserve and extend elite creative expertise and deliver personalized style recommendations using AI. "I've always thought of AI as an averaging machine," says Roope, who is also the AI Lead for Black Eyewear. "That's great if you're trying to get to 50%. But in creative industries, 50% is useless. You need to be in the top 1% to be noticed—and there's no signal for good and original in most AI systems."
Building a frame recommendation agent
with Gemini
From the beginning, Google Cloud stood out as the platform that could support Roope's ambition, with Gemini's multimodal capabilities offering a way to unify vision, language, and reasoning into a single experience. "Google Cloud was the first place where I saw these tools being demonstrated in a way that creatives could actually use," he says. "It wasn't just about raw power—it was about accessibility."
For Black Eyewear, collaboration between engineers and non-technical creatives was critical. The elder Roope needed to be able to influence the system without understanding machine learning jargon. Google Cloud's tooling made that possible. "With other tools, collaboration becomes the bottleneck. With Gemini, prompting and iteration are intuitive enough that we can move fast without endless translation," Barlow says.
Using Vertex AI Vision, Robert and Tomas labeled thousands of images to train multiple specialist models. Instead of trying to classify faces into generic categories, the team broke Robert's process down into discrete judgments, analyzing the nuanced interplay between facial structure and frame geometry. Each model focused on a single aspect of the face, allowing for much higher accuracy than an all-in-one approach. These insights are then matched procedurally against Black Eyewear's inventory to identify optimal frames.
At the heart of the experience is a web-based frame agent, powered by Gemini Flash and designed to replicate Robert Roope's expertise to allow customers to receive personalized recommendations at any time, from their phones. The system listens to conversational cues such as whether a customer wants something formal or informal, expressive or understated, masculine or androgynous. Those preferences reshape how the product space is explored, while the facial analysis remains grounded in visual data. "We struggled with other language models," notes Barlow. "They either sounded too generic or leaned into stereotypes. Gemini was the first model that could capture Robert's voice without massive prompting."
In addition to scaling Robert Roope's decades of optical intuition, Google Cloud AI is similarly scaling artist Jacqui Kenny's specialized AI prompting skills, demonstrating the synergy between human craft and generative precision.
Transporting the elite, personalized London boutique experience to a global digital audience
To complete the experience, Black Eyewear integrated virtual try-on using Nano Banana 2, the Gemini AI image generator and photo editor orchestrated through Gemini Flash.
What began as a potential multi-year R&D effort became a same-day integration. "We were blown away," Roope says. "In half a day, Nano Banana 2 was doing what we'd been trying to build ourselves."
Virtual try-on customers can see frames on their own face in seconds, with images that feel aspirational rather than clinical. The experience is intentionally designed as a marketing moment, not a sterile AR overlay. When users share or download images, branding and product details extend the in-store experience into social and messaging channels. "This gives us the capability to combine Robert's unique expertise, captured and recreated with AI, and delivered at a level of visual polish that is on-brand and catalog-quality," says Roope. Nano Banana 2 generates try-on images in as little as four seconds, at a fraction of the cost of earlier solutions.
While Black Eyewear is still early in its data journey, the qualitative impact has been immediate. Black Eyewear reports 20 percent sales growth, and customers feel more confident, more adventurous, and better prepared.
In physical shops, the effect is tangible. Customers increasingly arrive with a shortlist of frames generated by AI, reducing consultations that once took an hour to ten minutes or less. Even when customers don't buy online, the digital experience is accelerating in-store conversion and improving satisfaction, with integrated commerce links to drive direct sales.
Black Eyewear has also earned industry accolades for innovation, winning the Editors' Choice award at the 2026 RTIH AI in Retail Awards.
Looking ahead, Black Eyewear plans to include tighter integration with Shopify through Google's Universal Commerce Protocol, enabling agentic commerce experiences without custom builds for every retailer. The company will also launch facial anthropometry enabled by Gemini, generating accurate facial measurements that improve relative frame sizing and recommendation. Longer term, the team is exploring how this model could become retailer-agnostic—allowing any expert with a credible point of view to train systems that reflect their taste. "There's a future where opinion itself becomes a brand," says Roope. "Google Cloud is what makes that possible."
We were blown away. In half a day, Nano Banana 2 was doing what we'd been trying to build ourselves.
