You're not looney or nuts. Or at least if you are, you aren't the only one because I've found the same thing to be true. I don't have an explanation, but I don't really think it affects the sound, I would tend to think it's probably some kind of a brain thing like how music seems to sound better in a darkened room. I think the less visual information your brain is processing, the better job it does with the audio. Make sense?
Yes it does. As they did for Homer in an early Simpsons episode, bring me your form and I will stamp it with "Officially not insane."
In reality, I am a psychology professor (not a shrink, an academic), and the eyeglasses off phenomenon is simply a matter of attentional resource allocation. Humans are "limited capacity processors," meaning we only have a limited amount of mental effort to allocate to any particular task at any particular time. When you take off the glasses, you are reducing the current visual processing demands (meaning less visual input from the surroundings), and thus there is more attention and cognitive processing available for a concurrent auditory task (i.e., critically listening to the music). However, you probably do not go completely "blind" w/o the glasses with no visual input at all, so what also probably happens is that over the years of wearing glasses, you have formed expectations about what happens when you take the glasses off; namely, you purposely don't try as hard to process your visual surroundings, so there is also a learned motivational change in processing when the glasses come off. The net result, again, is more mental resources to apply to the audio task.
Some comedian has a line, maybe it's Steven Wright, who observed "When we are driving around trying to find an specific address, why do we turn the radio down?" It's the same phenomenon. You turn the radio down to allocate more attentional resources to the visual search task.
Yes, that's what i said,.....................only much much better.[]
