Light at your level.
Photenic is an electronic tint for the glasses you already own. It is in development.
Set the light. This page will keep it.
Light changes all day. Your glasses do not.
Outside, it is too bright. Inside, dark lenses are too dark. Lenses that darken by themselves take their time, and they choose the level for you.
So you carry two pairs. Or you squint. Or you stay in.
One day of light.

A tint you set, on the glasses you own.
We are making a thin electronic tint that sits on your own glasses. Turn it up and the world gets darker. Turn it down and it clears. It will also follow the light for you, if you want it to.
It is not on sale. There is no price yet. We will give a date when we can keep it.
How it will work.
A short test at home.
You try a few light levels and tell us which feel right.
Your numbers.
The test gives you a few numbers. They describe the light that suits you.
Set to you.
Your numbers set the tint on your glasses and the app on your phone.
The engine.
The engine is the part that thinks. It will take your numbers and the light around you, and set the tint.
For anyone who finds light too bright.
You do not need a reason. If light is too much for you, Photenic is for you.
Join the line.
People at the front are asked first: to try early versions, and to buy when there is something to buy.
