Forget about political correctness. What are the best technological options for totally blind people to see again or to see for the first time? We need real results, not promises.

You're absolutely right to focus on **real results** over hype or speculative promises. When we strip away marketing, political correctness, and futuristic hopes, here's a brutally honest ranking of the **best available technological options** - based on current **practical outcomes** for totally blind individuals (as of 2025):

---

## 🔝 **1. Sensory Substitution via Sound: The vOICe**

**Status:** Commercially available
**Best for:** Late-blind users with high motivation
**Technology:** Translates visual camera input into complex soundscapes

### ✅ **Advantages:**

* **Real visual information** delivered non-invasively through sound.
* Users have demonstrated the ability to **recognize objects, read printed letters**, navigate complex environments, and even interpret facial expressions - all through sound.
* Works **regardless of cause or age of blindness** (including congenital blindness).
* **No surgery, no implants, no health risks**.
* Runs on standard smart glasses and mobile phones.

### ❗ Caveats:

* Requires **significant training and brain plasticity** - it's not plug-and-play.
* Performance varies depending on user motivation, intelligence, auditory memory, and prior visual experience.
* Brain **imagery studies confirm visual cortex activation**, especially in late-blind users.

---

## 🧠 **2. Brain-Computer Interfaces (e.g., Neuralink Blindsight, Cortical Visual Prostheses)**

**Status:** Experimental (2024: first Neuralink implant in blind subject is likely in early-stage testing)

### ✅ **Advantages:**

* Direct stimulation of the visual cortex - bypassing eyes and optic nerve.
* **Phosphenes (spots of light)** can be perceived, even in total blindness.
* Potential to eventually restore crude spatial awareness.

### ❗ Harsh Reality:

* **No user has regained functional vision** yet, despite decades of research.
* Vision is **extremely low resolution**: even 3,000 electrodes can't match a VGA screen, and simultaneous stimulation is limited by power and safety (e.g., seizures).
* **Surgical risks, infection, rejection, and long-term biocompatibility issues** remain serious concerns.
* No solution for **plasticity gaps in congenitally blind** brains, where the visual cortex may have reorganized.

---

## 🧿 **3. Retinal or Optic Nerve Implants (e.g., Argus II, PRIMA)**

**Status:** Some discontinued, some still in trials

### ✅ **Advantages:**

* Provided **basic light perception and object localization** to certain users with residual retinal function.

### ❗ Limitations:

* Only work for very **specific causes of blindness** (e.g., retinitis pigmentosa).
* **Low resolution**, like looking through a straw with a handful of pixels.
* **Argus II has been discontinued** due to lack of practical benefit vs cost.
* Not an option for **totally blind** or **congenitally blind** individuals without retinal or optic nerve function.

---

## 🧪 **4. Optogenetics and Gene Therapy (e.g., Luxturna, optogenetic goggles)**

**Status:** Early clinical stage for a few rare diseases

### ✅ **Advantages:**

* Potential to **restore partial sight** in patients with specific genetic mutations.

### ❗ Limitations:

* **Not generalizable**: only helps people with specific gene defects.
* Often requires **wearing special goggles** to amplify light.
* Vision remains **low acuity**, mostly light/dark perception or movement.

---

## 🦾 **5. AI Smart Glasses with Descriptive Audio (e.g., OrCam, Envision, Seeing AI)**

**Status:** Commercially available

### ✅ **Advantages:**

* Excellent **object, face, and text recognition** through AI.
* Delivers spoken feedback for navigation and environment awareness.
* Easy to use, good for **social interaction**.

### ❗ Limitations:

* **Not true vision**: AI is interpreting the scene, not providing you with raw visual data.
* Susceptible to **AI hallucinations or errors**, which can be misleading or dangerous.
* Not immersive - can't give spatially structured visual experience.

## 🧠 Final Verdict:

If you want **real-world, functional, trainable “vision” for the blind - especially for totally or congenitally blind individuals - The vOICe and other visual-to-auditory sensory substitution systems are the most powerful technologies available today.** Everything else is experimental, overly narrow, invasive, or overly simplified.
