Very very cool. I have this condition - I got it randomly ("idiopathic" as opposed to age-related) when I was 22. At the time it wreaked havoc on my mental health.

    I am so sorry you went through this. How are you doing now?

    I got an ICL (Intra Collamer Lens) implant at 22 (25 now) and that ruined my night vision with ghosts and glares.

This is the sort of technology that will actually bring benefit into our lives.

Can't wait to see what advancements will be made in vision-related healthcare over the next 20 years.

I'm imagining a hacker sending infrared signals to a user to upload whatever image straight to their brain.

    And not a corporation to send advertising? What kind of cyberpunk dystopia is that?

This is incredible technology. Now do computer glasses with AI and you won’t need separate devices like phone.

Resolution, color depth?

    378 pixels, 1bpp

    The Phosphenes[0] patients sense will depend on what is left of the retina. People using earlier systems reported some interpolation happened. Maybe that is true of this device too.

    [0] - that is the name for the image the brain manifests in response to signals received by the visual cortex. Most of us experience them when we close our eyes and rub them, or maybe just see stuff that is unreal.

    > Resolution is limited by the size of pixels on the chip. Currently, the pixels are 100 microns wide, with 378 pixels on each chip.

    > the PRIMA device provides only black-and-white vision
