Hi Tatiana, and welcome to the group!

It's good to hear from you again. How are you doing? Still looking
for more light ? :-)

Look, lantanoprost darkens and moderate sun exposure (especially at
the seaside, during the early morning) lightens the overall iris
color.

There are two caveats though: Iris color is hard to define and its
modification is still more difficult to document.

For the first, you must remember that chemical and physical
components contribute to the definition of color, which is still an
impression and a concept more than a physical reality in the same
group with, say, body weight and body length.

For the second caveat, we have some experimental methods, like those
which spot micro-changes in the iris stromal pattern. Colorimetry is
still not usual for measuring iris color changes in vivo.

That's it. So this is more of a group about iris physiology than
anything else, including "iridology".

Hope this helps!
