Eight minutes
Every ray of light that has ever touched you began in the heart of the sun.
The Homecoming Company
Come home to your biology.
Step into the sun and something in you settles. That isn't a mood — it's every cell answering a signal it has always known.
Clinical study authorised · ULS Região de LeiriaIt wanders there for thousands of years, passed from atom to atom, before it ever reaches the surface.
Then it crosses a hundred and fifty million kilometres of nothing — today, in eight minutes and twenty seconds.
0:00minutes from the sun, today
It could land anywhere.
It could land on you.
Most days, it does not find you.
The severance
When did you last feel the sun on your skin?
Close your eyes. Hold the sun for ten seconds.
We didn't lose the sun. We lost fluency.

What Eclipsia is
Eclipsia is how you get it back.
A wrist instrument that measures what light actually reaches you, and how much of a day goes by indoors without you perceiving it.
That's the part nobody can feel. Not the hour you spent outside — the ones you didn't.
01 · Wear
Put it on.
Dawn to dark, it reads the light at your skin, wherever you actually are. Nothing to log. Nothing to remember.
02 · Catch
Meet your windows.
The app opens and closes them in real time — catch the morning light, meet the midday vitamin D window, step out when you've had your fill.
03 · Read
One number.
The Aura Score gathers a whole day's light into a single reading — an invitation to pay attention, never a verdict.
One number. So why does it matter to you?
The number isn't the point. You are.
Light sets the clock under your sleep, your energy and your mood, and it's how your skin makes vitamin D. You can't feel how much of it you're missing. Here's what changes when you can see it.
- GuessingKnowing
How much light actually reached you today, and when. Not the hour you remember — the minutes you got.
- Heavy morningsA clock that's set
Morning light is the signal that sets your inner clock, every day. Eclipsia tells you when it's open — and when you've had it.
- A lost winterA winter plan
When the vitamin D window closes for the season, it shows you the light that's still worth stepping out for.
- Fear of the sunFluency
When to seek it, and when to shade. The score is how you learn; the goal is to read the sky yourself.
More of the right light, at the right time — on purpose.
Clinical study · ULS Região de Leiria
We'd rather measure than promise.
So we're taking it to a hospital. A clinical study is board-authorised at ULS Região de Leiria, with its Department of Dermatology: three arms, sixty days, and vitamin D measured in the blood at the start and at the end.

Your skin
Determines your path.
The same sun asks more time of darker skin to make the same vitamin D — and gives fair skin less time before it burns. Eclipsia starts from yours.
Tap yours.
Typical minutes of midday sun for vitamin D with the window open, by Fitzpatrick skin type — the table the Eclipsia app starts from. Your own minutes move with the day's UV, how much skin you show, and the season.
Letter No. 01 · What I believe
This is why.
My son and me, walking into the light. I don't want him to grow up afraid of the sun, or hidden from it. I want him to know it — when to go out and meet it, and when to come in. Everything I believe comes back to that.
I believe the sun is not a threat to be managed. It is a language we have forgotten how to read.
I believe the body already knows. The biology is intact. What has broken is the relationship, not the hardware.
I believe mastery is kinder than fear. A person who understands the sun is safer than a person who hides from it.
I believe winter is when Eclipsia matters most, not least — because scarcity of light makes timing sacred.
And above all, I believe Eclipsia is not a wellness company. It is a homecoming company.

Read the whole letterThe Eclipsia band · join early
Light is next.
Sleep had its revolution. Movement had its. Light is the one still missing — the signal underneath all of them. The first bands ship to the people who join early.
Joining comes with your first sunrise: seven mornings in your own calendar, each with a line from Ricardo.
You're on the list.
We'll write when the band is ready. Until then, start with the light itself — left alone, your inner clock runs about eleven minutes long, and morning light is what sets it right.
Tomorrow, the sun rises again.
Be there for it. Two minutes is enough. Your calendar is made on this device; nothing about it is sent to us.
Afterwards, tell us what you feltFrom Portugal, with Love.
