I have seen this but only in my 1 bathroom mirror, after a shower when the sun is directly behind me. It is freaky.

So you can use Photoshop. Can you use Google Images or some other search tool to find real images of what you are asking about?
Why not? The only reason I can think of is that it may depend on the focal length of the lens on the camera and that can be anywhere from 500mm down to just a few mm in a smart phone camera. The eye is around 20mm focal length. Perhaps it could require a single element (cheap) lens on the camera but I can't think why.Inthewoods said:It won't photograph.

Still looks like Photoshop.Orthoceras said:In addition, a real photo of the ring was already given in this thread:
On what grounds? What would you expect to see? The rings would be around the camera lens in the image and their diameter would not necessarily be the same as what you see directly with your eye. As I mentioned higher up, a 20mm camera lens would be representative of a human eye.berkeman said:Still looks like Photoshop.
Ah, it looks like when I was trying to follow the link, I ended up back upthread farther with a dumb image with googlie-eyes, not the one that you folks are referring to now. That seems like a more reasonable image, agreed.sophiecentaur said:On what grounds? What would you expect to see?

It's a shame that the second image is such low quality. I'm sure it could have been a lot better and more convincing.berkeman said:That seems like a more reasonable image, agreed.
This is the most logical explanation to me. I was surprised when I saw the eye phenomenon when looking in my foggy mirror after my shower this morning. Normally, I wipe the large mirror but didn't this morning. Wow, it was freaky. So knowing a big about quantum mechanics and the like...I would have to agree with this submitter.Samimnot said:Here is some information that may shed light on the subject. It lies in the realm of anatomy. Have you ever witnessed the reflection from a cat's eye at night? It is due to the micro-spherical shape of each eye cell, as well as a macro-spherical shape of the inner eye-cavity. Light which enters the eye, scatters in a spherical pattern, towards the light source/observer because of both, the micro and macro structures of the eye. The former is like reflective beads on a projector screen or road paint. The second is like the secondary mirror on a reflector-type telescope. In a foggy room, this complex light-scattering effect would tend to produce a uniform glow emanating from the pupil, almost like a hologram of the inner eye, as opposed to a point-source. This hologram-like light pattern can illuminate the inner eye, and the area of fog around the pupil, from the perspective of the viewer or camera. In humans, this reflection is attenuated by retinal pigments. But if the incident light is strong enough, or the person has very fair complexion, eye-reflections can be bright enough to see, and bright enough to illuminate the area around the eye.
Is that surprising? The geometry would only work for small angles about the line of the 'average' direction of incidence where there's symmetry - i.e. small rings. For light with incident angles near the axis of the lens `(eye or camera) any halo rings would be fainter and fainter and with bigger radii.cesaravd said:To my eyes, the camera's ring is not visible. To my camera, my eye's rings are not visible.
There are 2-3 solar eclipses every year, with a total eclipse every 1-2 years. You see the upcoming one discussed more on English-speaking parts of the internet because it crosses the US, but there is nothing special about it from a physics perspective. And this thread is a few years old.Brighteyes said:There is a solar eclipse coming up soon
It has not.Brighteyes said:and the light from the sun has changed
Wherever did you get that from? The light from the Sun is constantly changing but only by very small random amounts (sun spots, solar flares, solar mass ejections etc. etc). Be careful about connecting facts that you read about without very good cause.Brighteyes said:and the light from the sun has changed
