    I couldn't agree more, astro with dark adapted eye not
    a good idea, for my eyes at least. We all have our own
    particular eyes, and a fair few of us think beforehand
    about the conditioning of our eye(s) in preparation
    for taking a sight.
    
    My only aim in suggesting the dark adapted eye 'test'
    with and without specs was to provide a demonstration
    of just one of those mysterious eye processes...
    
    Doing experiments on your own eyes is all part of the
    fun ....
