Please allow me a dissenting view! Certainly.
The suggestion that the Moon has nothing to reflect off is simply wrong. You 
can read a book by its light on Earth a quarter million miles away on a clear 
Full Moon night. It has an albeido of 7%! The fact that the Moon reflects light 
does not alter the fact that the Moon's (reflected) light has nothing to 
reflect off. The albedo has nothing to do with what I am saying. There are no 
clouds, no trees, no buildings, and there is no atmosphere. [OK -- no trees, 
buildings, atmosphere or clouds, but lots of rocks, big rocks and even bigger 
rocks ie terraine. Light reflects off all of these and albeido is certainly a 
relevant parameter.]
Now if you were standing on it [by this I mean the Moon] and there were 
scratches and dust on your visor, however small and/or sparse, the glare would 
certainly shut down your irises. Utter nonsense. The Moon must be at least as 
far, if not farther, away from the Sun as we are. When was the last time your 
iris "shut down"?! [I think this comment is based on a false premise. Perhaps 
you read "shut down" as "close completely"? Let me rephrase -- "reduce 
aperature".] But apart from that, and I think you may have the expertise to 
evaluate this suggestion, you don't have to be looking at a bright object in 
order for your irises to close down -- it is only necessary that light can 
enter your eyes from an object at any angle. I speak from the perspective of 
someone who both wears spectacles and sands wood. Paul, you would simply have 
to do the same thing that you have to do here, either tilt your head back or 
use your hand as a blinker. [If you can't imagine
 this I'll draw you a picture, but that takes a significant amount of time so I 
hope your visualization process is working. You are standing on the Moon 
surrounded by reflecting objects. There is dust on your visor. There are minute 
scratches on your visor. Regardless of where you look or hold your hand, light 
is reflecting off these visor transparency deficiencies into your eyes. 
Everything inside your helmet -- including your face -- is reflecting this 
together with any direct incident light which also reflects off the 
transparency deficiencies and the inside of your visor into your eyes. The 
irises reduce their apature. If you can't imagine that then try imagining this. 
(I assume you wear spectacles? If not, then sunglasses would be even better). 
Take these vision enhancing optical devices and give them a light dusting, 
perhaps by holding them close to and downwind of the vacuum cleaner bag as you 
shake it to remove the fine particles. Carefully place
 them on your head and in full sunlight, look into a shadowed area -- an opaque 
fence between you and the Sun would be ideal. Now tell me if you can make out 
anything in the shadow and if not suggest a cause.]
As the shuttle crew have (finally) confirmed, you can see stars in space, and 
those stars are "BRILLIANT."[Yes, compared to the blackness of space. But few 
of their photons reach your eye. If you irises have reduced their aperture, as 
influenced by local and incomparably greater photon density, you won't see 
them. Besides, as has been pointed out by Philip -- they were rather busy and 
checking that the stars were still in their accustomed places was not an issue.]
[I note that you have not attempted to address my suggestion.]
Neville.
