We know, for example, that like color blindness can happen in lots of places.

It can happen in the brain or it can be because of the retina itself, because of the actual cone receptors in the retina.

We know that.

So if I if I had my eyeballs replaced with a colorblind person's eyeballs and it was perfectly synced up nerve to nerve by some surgeon, I would not see those colors anymore.

At first I thought, well, I don't know.

My body might still like expect to see, you know, red and green divisions.

And so it might fix it itself.

But colorblindness can also be induced and it can be non-genetic.

It can happen to someone who used to be able to see the colors.

I didn't know this until this morning.

I thought it was purely a genetic net, a genetic thing.

That is one thing I... I did not even know that.

But you could also damage someone's brain.

If they have swelling in the occipital lobe, in the back where vision is first processed, can lead to colorblindness, and so can medications.

As it turns out, one of the chemicals in Viagra can lead to blue-yellow colorblindness.

Yeah, it's a trade-off, you know?

It's a good life lesson.

I don't know if it's permanent or not, but I'll do some experiments later, and I'll let you know what I find.

There's also a medication used for treating tuberculosis called ethambutol, and that can lead to red-green colorblindness.

Vitamin A deficiency can cause colorblindness.
