AFAIK angina comes from the Latin word angere which means to suffocate.

Angina pectoris being suffocating chest pain, often accompanied by shortness of breath.

And Ludwig angina litteraly suffocating a person via swelling.

I think the main issue is that people expect a magic fix. This is a common problem in the world today. Many things are massively overhyped and then turn out to be a huge disappointment to many people because they are not as perfect as the hype lead them to belive.

I belive these glasses can be a useful tool to some one that struggles with color blindness. But just that. A tool. Not a fix. By understand what these glasses can actualy do and their limitations someone with color blindness can potentially get a lot more information what the hues and colors they wouod normally struggle with. They won’t however maks them suddenly see in perfect color.

I hope they help your wife, and I belive that if she uses them as an aid, not a fix, they will help her a lot.

Best of luck.

This realy is the key point imo.

There are people out there that can give a 100k+ gift to their partner other.

According to Google there are about 1.3 million households that make over 500k a year in the United States. That’s not a big number compare to the total population but it’s a big number.

Those families and many others are able to afford something like that if they want too. Notice the homes in those commercials are always very nice aswell. If you cant afford that, then you are simply not the target audience.

I know i sure as hell can’t.

Everyone has a responsibility for their own safety. We should do what is reasonable to reduce harm and risk to others, but there is only so much that can be reasonable. If a person wears dark clothing, doesn’t use crosswalks, doesn’t check for cars etc at what point does their safety become their responsibility?

That only works in more urban areas.

Its impossible to covered every road in lights and it can get very dark when you are far away from a city. Same with public transit. I am all for it, but it’s only reasonable in more densely populated areas. There just won’t be enough people using it in th middle of nowhere to just something like that much less staff it.

Meanwhile helping cars see people even in those less common and more difficult situations is a good thing. Why would you NOT want your car to be safer for others around you?

You joke, but that’s kindof a thing.

The occipital lobe is responsible for us being able to proccess and turn the info our eyes gather into what we see. Severely damaging is can make us be unable to process the info our eyes collect and be effectively blind. Even though there is nothing wrong with our eyes.

You can have a stroke in your occipital lobe and just wake up blind. Or get hit in the back of your head and lose your vision.

Basicly forget how to see.
