I can 'imagine' in great detail, have a good visual/ auditory memory, but there is no real picture or sound. It is black / silent. I never forget a face just can't picture them.

I found out about this via an article posted here when I was 45 years old, now 4 years ago.

It never felt and does feel like a disability in any way.

Dreams in contrast are a full sensory experience for me, so the route back from memory to senses is there, only it is blocked when I am awake.

Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp.

BTW maybe you should add (2016) to the title.

My wife really sees 'extra' images when imagining with eyes open and closed.

I can imagine very well but don't see anything, so no visualisation.

With eyes open I see what is in front in me, and imagine (ltterlaly) what I am thinking about. This can be in high visual detail, but with no picture. With eyes closed it is strange enough harder te imagine, because the black is all consuming.

Long story short:

I think you might have aphantasia but don't know or acknowledge it yet...

I think especial the other way around.

My wife for sure has a vivid visual experience, and only sees black when asked to see black. So, I don't think people without aphantasia will be identified having it with the question. I also was very specific with all black, not black and an image.

Asking a colour might identify people who do not know they have aphantasia

Because some people I've asked who think they can visualise, say they actually don't see anything, but imagine seeing. So what they see with eyes closed, is 'black'. That's why I've used that question. But they might not know the colour when not told in advance.

Most people do not know they are supposed to 'see' something when imagining something. Same goes for hearing.

I can't do both and discovered this when I was 45.

Like many others I do dream in full colour with sound and I never forget a face.

When doing a quick round at work asking people about it, because I was amazed, I've learned two things.

1. About 50% of the persons asked, confirmed they objectively only see black when closing their eyes and imagining something.

2. Most do not care at all about this subject and are not interested to explore this further.

The protection is the fact you just can't get a mobile payment terminal without a whole "know your customer" due diligence process, so the fraud traces directly to the ultimate beneficial owner of the company to which the payment acceptance contract of the payment terminal was provided.

This is the reason this fraud is non-existent in Europe, where tap to pay is already used for years.

Latency is very low which is very important for this use case. Look on YouTube for demos.

Be sure to get checks regularly and practice extra good eye hygiene, because they do have a higher risk of infections, also eye doctors do not recommend them.

Biggest drawback I experience are coronas around bright lights at night, but you do get used to them. I can conformably drive a car at night, because the sight is sharp. The extend also varies from person to person.

If you can tolerate the lenses with your eyes open, you can also already wear them in the evening if you need perfect sight in low light.

On topic: you cannot permanently reverse myopia, but it gets better when you get older for some people.

Ortho-K lenses can however be used by children to stop myopia from getting worse.
