Color blindness is also known as color vision deficiency.
It's usually inherited and it's more common among men than women.
People with the condition perceive colors differently than those who don't have it.
There's no cure for color blindness,but there are some computer applications that help people distinguish between different colors and there are lenses available that are sometimes effective if they're used in bright light.
If I make a steak, I'll bring it in thinking it's totally done and it will be really rare.
I just can't see that it's read.
It's probably unhealthy.
So, I'm out with a couple of CNN producers who also happened to be color blind and that these glasses are supposed to help with that.
OK. I think this kind of work.
Let me explain color blindness because it doesn't mean that you see the world in black and white.
It means that some colors may seem a little duller and others may just blind together.
And it's not as rare as you might think.
It affects between 8 percent and 12 percent of men, and up to 1 percent of women in the U.S.
I definitely see more shades, like that tree that looks kind of yellow looks actually more orange.
That one back there?
Yes, that one back there.Yes.
And this one right there is a little bit darker than that one.
According to their online tests, Jack's eyes absorb too much green light.
He's always struggled with the difference between blue and purple.
Does it look any different to you?
Things look-I think a little more vivid, like I turn the saturation up on the TV almost.
Wendy's eyes on the other hand don't absorb enough green light.
Before, could you see like the difference between the trunks and the trees and the leaves?
No. And now, I can.
Now you can see that?
Yes. That's amazing.
They're both forms of what's known as red, green color blindness.
The thing is, though, it's kind of misnomer, seeing too much or too little green changes the way you see other colors.
Purple and blue for example can start to blend together.
What color are those flowers behind us now?
Those look purple.
Now, take them off. What color do they look like?
They look blue.The glasses work by shielding your eyes from the part of the spectrum where red and green overlap the most.
This is a blue purple, but it's definitely purple.
I think that's a little more purple with them on.
I wouldn't say it's a big change.
The world looks significantly different to me.
Do you like it better?Yes.
Bottom line, they work pretty well for Wendy, not as great for Jack.
But I can tell you, from personal experience, I saw the world in a whole new light.
We all have been there.
You get to the edge of the diving board and you're just not sure yet you want to take the plunge.
This penguin, he's in the same boat.
He gets up to the edge and then, nope, I'll waddle back on over here for a while.
And then he tries again, just about-nope, not going to do it.He'd be a lot more graceful in the water if he'd just got in, but there's something unseen working against him, it's called gravity, and it eventually wins.
Beforehand, he kind of looked like a fish out of water.
People were asking, waddle he do about this?
They probably expected him to flip out and he was like, look, it's flightless not frightless and maybe I just don't want to give bird by swimming in my tuxedo.
