Here is my answer from Mad Scientist,

Hi Jennifer,
I am 99.99% certain that the fluorescence seen in some human eyes is NOT
from green fluorescent protein. Something very seriously bad would have
had to transpire in the food chain in order for that to be in our eyes
(or it would have had to be put there on purpose).
As to what it is, I think the most plausible explanation I have been able
to find is that there are a series of compounds that exist in our eyes
that are fluorophores. The two major types are called:
3-hydroxy kynurenine glucoside (3-OHKG), and
4-(2-amino-3-hydroxyphenyl)-4-oxobutanoic acid O-glucoside (AHBG)
These compounds are believed to act as UV filters, especially in younger
people. In a younger person, these compounds are fluorescent, but when
that person ages, there is a change in those compounds (possibly due to a
reaction between the compound and lens crystallins in the eye) such that
the amount of fluorescence produced by these compounds increases (or at
the very least the fluorescence produced has a longer lifetime, so you
can see it longer). These compounds are caused to fluorescence when you
shine light of wavelengths between 295 and 400 nm (within the range you
mentioned).
Hope this helps!
Karin
This brings me right back to my reply number 6 from the first page of this thread,

This may be the compound responsible for this it is related to aging but why do the eyes of children express it strongly?
Synthesis of 2-amino-3-hydroxyacetophenone-O-â-D-glucopyranoside : a fluorescent compound from insoluble protein fraction of aging human lens
but from below this seems to be a newly found one seems a little different.
A new fluorescent compound was isolated from human lens insoluble protein fraction, and was identified as 2-amino-3-hydroxyacetophenone-O-β-D-glucoside
cat.inist.fr/?aModele=afficheN&cpsidt=4104898It also can be from protein modification which is I believe what we are looking at .
I first came across this in an article saying it was a newly found compound from human lenses. It plays a role in breakdown abnormal calf proteins . This process results in crystallization of the human lens, I believe.
I once posted a thread here about color blindness, it effect the ability to see blue light properly . When I took an eye test that was what the results said, I had a rare type of color blindness to some dark shades of blue light. Blue light or the equivalent radio waves are what are being utilized in some viral brain control techniques . I do not know if that is a co-incidence but well
hmmmmmmm???

so lets compare

2-amino-3-hydroxyacetophenone-O-β-D-glucoside
the new on bottom.
now compare with the compound Karin sent as a possiblitiy.
