Inspiration

One of my freinds had forgotten their glasses. With insurance not covering a new pair for another year, the financial burden quickly overshadowed the hackathon itself. This frustration led us to a realization—why are glasses so expensive?

In countries like Nepal or Colombia, basic glasses can cost as little as $10. While high-tech lenses justify some markup, even simple plastic frames remain costly. This sparked our idea: leverage 3D printing and computer vision to create affordable, custom-fit glasses.

What It Does

Our app scans a user's face using OpenCV, measuring key facial dimensions to generate perfectly fitting glasses. Through an intuitive interface and the Onshape API, users can:

Select frame styles, colors, and customize their design
Export and modify measurements for fully personalized glasses

How We Built It

We developed our platform using:

Technology	Purpose
Next.js & TypeScript	Frontend development
Python & Flask	Backend processing
OpenCV	Facial measurements
Three.js	3D visualization
Onshape & Onshape API	CAD modeling

Challenges We Faced

One of our biggest hurdles was working with the Onshape API—it’s less intuitive than other modeling tools like Blender or Fusion 360.

Handling complex geometries for unique frame designs also proved challenging, so we refined our approach to be simpler and more adaptable.

Accomplishments We're Proud Of

✅ Successfully implementing OpenCV to extract precise facial measurements
✅ 3D printing functional glasses directly from our app-generated designs
