^^^Pranav is an Indian citizen who is completely blind. He’s an exceptionally bright young man — he was accepted to Stanford University, though his family couldn’t afford to send him there. My son met him accidentally a year or so back.

His company, Meta, supported him, and he demonstrated the Meta AI glasses to Narendra Modi. The glasses use AI vision to describe surroundings — including identifying colors, but *much* more — effectively acting as real-time visual assistance.

I’ve seen firsthand how transformative this kind of device can be for blind individuals.

Genuinely curious: how does a completely blind man understand colour?

Genuinely curious: how does a completely blind man understand colour?

A person who is completely blind doesn’t “see” color the way sighted people do. But color is also information — and information can be described.

Assistive AI glasses convert visual input into spoken description. So when the device says “These socks are navy blue” or “The mango is mostly yellow with some green,” it’s doing the same job our eyes do for us — just through audio instead of vision.

In practical terms, it helps with all the everyday things sighted people do independently:
- buying and matching clothes, - checking how ripe a mango is by its color, reading a restaurant menu, road signs, big colorful poster... even reading physics books or lecture 'reading the black-board.


In other words, it reduces dependence on a human assistant and gives real-time access to visual information. Color isn’t experienced visually — it’s understood contextually. And that understanding is what enables independence.

It is really life changing ..and seen it how it plays out in real life: imagine a blind professional walking into a meeting. The glasses quietly say, “Conference room. Five people seated. Raj is on your left. Screen at the front.” They can locate an empty chair, find the coffee table, glance toward whoever is speaking, and even follow a PowerPoint as key visuals are described. Later, they can “look” at a photo relatives sent and hear: “Two children on a beach at sunset, both smiling,” or watch a movie with rich audio description — much like the audio-described tracks already available in many films — and fully participate in the shared experience. It’s not about seeing in the traditional sense; it’s about accessing the same visual context the rest of us take for granted, without needing a personal assistant at their side.

^ A lot of progress has been made on enabling the deaf to 'hear'

If/When the scientists invent a device which can enable the blind to see, it will, in my opinion, be the greatest scientific invention of all time.

Describing a scene is hardly vision. No more than describing the taste of sidamo coffee is tasting.

The blind will definitely see. But it will take neural implants connected to optical sensors. The optic radiation may be bypassed by cortical implantation. It will mean an integrative processor to simulate that input.

I was about to say the same thing. A genuinely blind man will be told that this is a colour, but won’t understand what it is or differentiate between yellow and red (without putting it in sun)

This is not to take away anything from the utility of said devices though.

Same Meta glasses are used in this story
