You have caught ONE example, in ONE photo, of a visor being up.
Really, go read about the missions, and the EVAs, from first-hand accounts BY the Astronauts themselves.
The Human eye does NOT adjust "within a few seconds" from bright light, to dim.
The other way? YES, of course. We go from DARK to bright? The eye adjusts VERY rapidly.
Other way, takes longer. THAT is why we have the term 'night vision' in our lexicon.
Why, oh why do some of us try???

Actually, the visor used a gold layer, sandwiched into the visor.
On some EVAs, Astronauts had to raise the visor, because it was scratched (from the grit of Lunar regolith), or because it impeded and deducted from
clarity, in darker corners, where things were in shadow...
Also, it altered the perception of color.
