sight sync

Buying glasses online can feel overwhelming, and I wanted to understand why while making the experience simple, clear, and confident. I began by studying how people shop for eyewear online through ethnographic research and competitor analysis and discovered that users often hesitate around fit, trust, and decision-making. These insights helped me define the target audience and thoughtfully structure the app to reduce friction, using a content inventory and sitemap to map the experience clearly and logically.

The biggest challenge was scale. With many features and screens, even small inconsistencies could quickly increase cognitive load. Early usability testing showed that users hesitated during frame selection and lens configuration, prompting a redesign of flows, clearer system feedback, and more consistent interaction patterns.

Each testing round informed meaningful changes rather than surface-level tweaks. After the second round of usability testing, task completion reached 100%, and Task Ease (SEQ) increased from 4.2/5 to 4.7/5, indicating a noticeably smoother and more confident experience.

The final product reduced second-guessing and supported informed decisions by turning eyewear shopping into a guided, reliable experience that builds trust through clarity and consistency.
