Transforming the PDP into a guided lens decision journey
Costa del Mar's customers chose lenses based on color preference, not performance. I redesigned the Product Detail Page into a guided experience that shifts decisions from taste to context. The new, data-driven flow boosted add-to-cart rates by 4.2% and the conversion rate by 2.7%, building user trust and clarity.

THE CONTEXT
A loyal customer base with a hidden problem
Costa del Mar is an iconic brand with a deeply loyal following, especially among fishing and on-the-water enthusiasts. Customers trust the brand implicitly, often for generations. However, user research uncovered a critical disconnect between their best-in-class lens technology and the e-commerce experience.
Customers were loyal to the brand, but their choices were based on instinct, not insight.
This meant customers were often buying the wrong tool for the job, leading to a subpar experience and representing a massive loss of revenue and brand equity for the business.

As the sole Senior UX/UI Designer for Costa del Mar within EssilorLuxottica, I owned the design process end-to-end. I partnered with research, business, and IT stakeholders to frame the problem, define a data-driven strategy, and deliver a solution that was desirable for users, technically feasible, and valuable for the business.
My goal was to shift the conversation from "what color do I like?" to "what lens do I need?"

THE CHALLENGE
Navigating business skepticism and technical constraints
The path to the final solution involved overcoming two critical hurdles that required more than just design skills.
1.
Proving the value: Turning skepticism into buy-in
The business team was initially hesitant about a "lens-first" selection flow, fearing it would add friction and hurt conversion. Rather than debating opinions, I let the data speak for itself. I designed two variants—a classic picker versus a "Double Selector" for lens and frame—and we ran a focused A/B test.
The results were clear and decisive. The Double Selector variant delivered:

2.
Adapting on the fly: Solving an engineering blocker
Mid-project, the engineering team flagged a significant risk: our proposed design would trigger too many backend API calls, threatening to slow down the page and harm site performance.
Performance is non-negotiable. I immediately partnered with the developers to understand the bottleneck and pivoted to a simpler interaction pattern that preserved the core guidance and clarity of the user experience while removing the technical risk.

THE IMPACT
Measurable, sustained, and business-changing
After a successful test launch in a single market, the new PDP was rolled out globally. In the U.S., Costa’s primary market, the redesign delivered significant, measurable results:
The strongest evidence of its success is its longevity. The design has remained essentially unchanged in production since its launch in 2021, proving its sustained value in a fast-moving e-commerce landscape.

Despite relying on Costa for performance, their online purchasing behavior was driven by aesthetics. The data was eye-opening:
