I agree.... at least for me. Whether cycling, jogging, hiking, playing ball, or just hanging out.... the "normal" appropriate gear avoids lots of inconvenience. As well as provide needed safety and protection. I forget that first aid centers and emergency rooms regularly treat people who are over-exposed for the conditions they are in. And conditions believed to be caused form long-term exposure to things like the sun.... is another matter altogether.

But does cycling provide specific dangers/hazards that require specific clothing.... or as this thread asks: "glasses labeled as cycling sunglasses".

I don't think so.... even though mine are... and I prefer wearing/using regular cycling gear most of the time (when cycling). But I can't see how a pair of Wayfarer sunglasses would be inadequate for sun... or a pair of motorcycle goggles too much for cold wind.
