The holographic display system in Focals seems complicated, but it works on some simple ideas:

The first step is producing light, specifically red, green, and blue. Combining these three colors lets your display create any color.

The light is then bent and focused to create the text and images of your display, before it gets sent out the projector window.

The holographic lens (crafted expertly at our manufacturing facility) is within the right lens of each pair of Focals and contains a special transparent film embedded in the lens itself. This film is  transparent and designed to only interact with three specific wavelengths of light - red, green, and blue - and lets everything else pass through unchanged.

When our specific wavelengths of light hit the transparent film, it acts like a mirror and bounces the light back towards your eye placing the image directly in your line of sight where only you can see it.

Unlike a screen, the display on Focals only exists in the eye of the wearer, making it discreet and unobtrusive.

It's technology that’s there when you want it, and gone when you don’t.
