Acuity Check:
At-Home Eye Exams
Acuity Check is an innovative mobile app designed to make professional vision testing accessible and affordable from anywhere.
As the lead designer, I simplified complex real-world testing steps - like environment setup and distance tracking - into an intuitive, minimalist digital experience that minimizes cognitive load.
To turn a complex clinical eye exam into a self-administered home test, I created an intuitive, accessible visual language. My main focus was solving three critical friction points: helping users calibrate the 3-meter distance, forcing landscape mode, and designing clear error-recovery loops. Using clear UI icons and interactive micro-animations, the onboarding guides users smoothly through the test while keeping cognitive load to a minimum.

Interactive gauge that guides users as they step back 3 meters
I started with a short video to explain the test setup. However, usability tests showed it took too long to load, and many users lost patience and dropped out.

To fix this, I broke the guide into a 4-part carousel so users could move at their own pace. I tried using high-quality video GIFs, but we still ran into loading issues.
Finally, I switched to simple micro-animations that loaded instantly and were much easier to follow. This improved user understanding and increased our conversion rate by 5%!

Another challenge was showing users that the app was listening to them from 3 meters away. After usability tests showed that a simple speaker icon wasn't clear enough, I designed an active sound wave animation that moves as they speak to give instant, reassuring feedback.
Final Flow
Throughout the product development process, I kept the product's goal in mind and in addition to creating a visually appealing design, I aimed to achieve these objectives. This resulted in a significant reduction in the product's onboarding time and an improvement in the conversion rate.
