Sphyrna—water sports sunglasses

Float upright, never lost sight.

Collaborating with Hwa-Meei Company, we have designed water sports eyewear specifically tailored for aquatic activities. With its innovative floating and color design, this eyewear ensures users can easily retrieve it after falling into water.

CAUSAL RELATIONSHIP MAP
EXPERIMENT - BUOYANT SPEED
Modular Buoyancy Speed Test
Modular Buoyancy Speed Test

To quantify the effect of geometry on buoyant rise time, We assembled modular prototypes using 3D printed components and tested them in artificial seawater.

The experiment isolated variables such as displacement volume and center-of-mass alignment, enabling comparative evaluation across multiple configurations.

Buoyancy Orientation Simulation

A simulation comparing horizontal and vertical float orientations shows a significant increase in visible area when the eyewear remains upright.

EXPERIMENT - COLORS
Color Visibility Test
Color Visibility Test

Participants searched for eyewear colors on a simulated ocean surface, and their response times were recorded.

The test reveals which colors remain most visible against glare and water movement.

EXPERIMENT - VENTILATION DESIGN
WIND TUNNEL TESTING

We built a small scale wind tunnel to test how different vent placements influence fog dissipation.
By comparing multiple opening configurations under controlled airflow, we identified which geometries clear moisture the fastest and provide the most effective ventilation during high exertion water activities.

EXPERIMENT - AIRFLOW DESIGN
Airflow Intake Geometry Experiment
Airflow Intake Geometry Experiment

We tested multiple angles and frame geometries in a controlled wind tunnel to examine how airflow enters the eyewear.
By comparing configurations, we identified which shapes allow efficient airflow without causing excessive fogging or light leakage.

Form Direction — Y2K Inspired
Form Direction — Y2K Inspired

The final form combines insights from airflow and buoyancy testing with the company’s Y2K design direction.

The geometry reinforces functional needs such as ventilation efficiency and stability on water while adopting bold curves and futuristic silhouettes characteristic of Y2K aesthetics.

This was my first experience with lean design. It sharpened my ability to work efficiently while prompting deeper questions about how optimization and innovation can coexist.

The industry collaboration strengthened my collaborative practice, and even experiences outside the project, like learning to surf, broadened how I observe and respond to design challenges.
