"Hmmm, i remember when all you could get was black. I don't think DIR was around back then."
I don't ever remember such a time, masks were available in white, yellow, orange, various blue colors and of course black and I have several such masks. You or correct, non were translucent but only because it had not been thought of. The return to black is DIR driven, that is my opinion, I am not claiming any facts. Do all of those "window" masks with all the various panes in them allow "reflections" and glare off the glass, I would think they might as well but have never heard that complaint against them, maybe so.
I am looking at an old Voit add here from the early 60s, the wet suits are multi colored prints---not solid---not striped on black, but greenish and almost camo looking. The masks are mostly blue and available in black as were the fins. The tanks look white. They don't got no BC. The idea that everything used to be black is not true or that black was even the main color in fins and masks. The Voit fins were made in many colors as were USD fins and masks and wetsuits were out in blue, yellow, black and various striped seams and patterns. Black was not considered a universal color, I was there. This concept to the best of my knowledge and opinion did not come into being until fairly recently and I have read several DIR sites that state a black mask is prefered, thus my beleif they are the trend setters for this Back to Black trend. In those times we considered all black to be themilitary frogman look.
I heard this on Public Radio, an interview with a Coast Guard lady, the subject was terrorism and reporting suspicious activity. She matter of factly stated that citizens should report such activity and one of the things she used as an example of suspicious activity was scuba divers dressed all in black!!!!!! Yep, hand me that clear mask and those yellow fins please! N
