Inspiration
The human eye is a biological marvel, yet it is often outmatched by the animal kingdom. We were inspired by animals that can navigate extreme light shifts with ease, while humans suffer through a painful "blinding" lag when stepping into the sun or waiting for pupils to dilate in the dark. Lumen-Sync was born from the desire to bridge this evolutionary gap. We engineered a smart contact lens system that acts as a physical aperture for your body, dynamically thinning or thickening its tint to ensure your vision is never outpaced by your environment.
What it does
Lumen-Sync is a high-performance "Light Management System" designed to prevent photo-stress and eye fatigue. The smart contact lenses track ambient light levels in real-time and automatically manipulate the lens tint to keep your vision within a comfortable, safe range. Through the mobile control panel, users can monitor their Exposure History, view Biological Pupil Dilation, and check Post-Filtering Eye Fatigue. For those seeking precision, the app provides a manual override via a tactical Aperture Dial, allowing for total command over visual exposure.
How we built it
The journey began in Figma Design, where we crafted a rough draft of our "Tactical Red" aesthetic—a palette chosen specifically because long-wavelength red light does not trigger the eye’s blue-light receptors, preserving night vision during app use. We then transitioned into a high-iteration development phase using Figma Make. By leveraging advanced prompt engineering, we transformed our static wireframes into a functional, interactive prototype, meticulously refining the component logic until the digital experience mirrored the physical behavior of a lens.
Challenges we ran into
Our primary hurdle was balancing technical depth with extreme legibility. We struggled with making complex statistics, such as the Exposure Tracker, readable in low-light conditions. We also focused heavily on signposting—ensuring users could instantly distinguish between a draggable control, like the Aperture Dial, and a static readout, like the Environment Brightness gauge. Solving this required several redesigns of our information architecture to ensure that tactical utility did not come at the cost of clarity.
Accomplishments that we're proud of
We are incredibly proud to have developed a very clean and functional app that is as visually appealing as it is scientifically grounded. We successfully translated dense optical data into an intuitive experience that any user can understand at a glance. Seeing the Post-Filtering Strain gauge respond dynamically to the Lens Filter logic was a major milestone. We achieved an aesthetic that feels like professional equipment while remaining accessible to anyone looking to protect their long-term ocular health.
What we learned
This project provided a deep dive into Prompt Engineering and User Experience (UX). We learned that a great product is defined by how effectively it communicates its power to the user. We discovered the importance of breaking down complex information into digestible "sensory bites" and learned how to use info icons and simplified labeling to guide users through a technical environment. Ultimately, we learned what it takes to make technology feel like a natural, understandable extension of the human body.
