Increased conversion in a 3D facial scanning experience

I designed the experience of a B2C app focused on purchasing personalized eyewear through 3D facial scanning and prescription management.

The product is part of a HealthTech ecosystem that connects users, optometrists, and manufacturing processes, enabling the production of eyewear tailored to each person’s facial anatomy.

The challenge

The app’s main flow allows users to:

  • Browse and select eyewear models
  • Perform a 3D facial scan directly from their device
  • Manage their prescription by uploading an existing prescription, taking a photo, or scheduling an appointment with a professional
  • Preview the result through a Virtual Try-On experience
  • Complete the purchase

The challenge was to organize a complex process into a clear and understandable experience that guided users through each step without causing drop-offs.

Problem

There was friction across several critical points in the flow:

  • The 3D scanning process generated uncertainty (accuracy, camera usage, data concerns)
  • Prescription management interrupted the experience
  • Many users did not have a prescription and did not know how to continue
  • The overall process felt complex and unclear

This directly impacted conversion rates and the quality of manufacturing data.

What I did

I focused on simplifying the flow and reducing friction at every stage.

  • Reorganized the experience into clear, progressive steps
  • Designed a scanning onboarding flow that prepared users before entering the SDK
  • Added real-time feedback to guide the scanning process
  • Created a flexible prescription system (upload, photo, or appointment)
  • Integrated optometrist scheduling directly into the flow
  • Defined states, validations, and messaging to provide clarity throughout the experience

Impact & Metrics

The solution is already implemented and actively being used, positively impacting both the user experience and operational processes.

  • Created a smoother experience between the B2C app, optometrists, and internal operations
  • Turned 3D facial scanning from a barrier into an understandable step within the journey
  • Reduced purchase friction by offering clear prescription alternatives
  • Integrated professional services without removing users from the flow

    Vivo en León, Guanajuato y todo el proceso lo hice de forma remota a través de la app, súper fácil y rápido.

    Los lentes quedaron perfectos en medida y estilo, se nota la calidad y el cuidado en los detalles.

    Además, la comunicación una vez hecha la compra fue constante y el servicio al cliente impecable. Totalmente recomendable si buscas personalización, comodidad y un servicio confiable a distancia. 🙌
