1 billion people are vitamin D deficient. I
n Portugal, one of Europe’s sunniest countries, 66% of adults don’t get enough. The problem was never the sun. 
It was that no one gave us the intelligence to master it.

Eclipsia is building the OS for Human Light Optimization: the first wearable platform that moves beyond UV protection to personalized light mastery. 

Dual UVA/UVB sensors to capture the full UV picture. 
Our proprietary Aura Score tells users WHEN to get light — not just how much — personalized to skin type, location, season, and biology.

They measure WHAT. We measure WHEN.

Where we are: Clinical validation underway. 
Hardware developed in partnership with University of Coimbra’s Institute of Systems and Robotics. 
Winners of ArriscaC 2025. 
Working prototypes transmitting real sensor data via BLE.

Where we’re going: To build the platform that turns a wearable into an OS.

Movement was solved. Sleep was solved. Light is next.
The Third Wellness Revolution. 
From Portugal, with Love.
