How it will work.
Nothing here is finished. This is the plan, in the order you will meet it.
-
A short test at home.
You open the test on your phone or laptop. It shows you a few light levels, one at a time. You say which feel right and which are too much. It takes a few minutes. It is not an eye test and it does not replace one.
-
Your numbers.
The test gives you a few numbers. They describe the light that suits you. They are yours, and you can change them at any time.
-
Set to you.
Your numbers set the tint on your glasses. They also set the app on your phone, so words and bright things on screen suit you too.
How dark is dark.
A fixed lens stays at one point.
A lens that darkens by itself moves between two points, slowly.
The aim for Photenic: you choose the point, and it gets there in a moment.
| Category | Light let through |
|---|---|
| Category 0 | over 80 to 100 percent |
| Category 1 | over 43 to 80 percent |
| Category 2 | over 18 to 43 percent |
| Category 3 | over 8 to 18 percent |
| Category 4 | over 3 to 8 percent |
What is not decided.
The shape. It will sit on your own glasses. Whether it clips on or fits over them is still open. People in the line will help us choose.
What we will not do.
We will not say it works until it is tested. We will not show a date we cannot keep.
