The key to keeping your lenses from fogging up is to keep air circulating behind them. The shape and position of the cuts are designed to best address ventilation while still keeping debris, rain, and sunlight out of your eyes.
Of course, if you stop moving, the lenses will inevitably fog. However, the vents in the lenses will ensure that once you do get moving, your vision will clear within seconds without you having to take off your sunglasses to wipe them clean. Short of attaching mini fans to your sunglasses, vents are one of the best options for clear vision. Replacement Lenses Have a pesky scratch on your favorite sunglasses?

Just one question for anyone. There are vented hoods and scalloped hoods. We're not talking about the same thing are we??

The best of the vented hoods, e. And light from behind can't strike the front element directly either. Of course, if the external light source like a spotlight is angled directly at the front element, it will generate flare, but that would have happened regardless of whether there were vents. Older lenses frequently suffer from overall contrast loss at wide apertures if used without a hood. Typically you will see a diffuse brightening in the center of the image.
Put a hood on and the effects of the non image forming light on the lens will go away. With my newer lenses, though, this kind of flare is very well controlled, and I use lens hoods for protection and not much else. The question was about vented vs non-vented hoods. I use lens hoods with all lenses, all the time. It helps in all cases, both for protection and for flare prevention.
The lenses vented hoods are designed for are also designed for rangefinders. Using the lenses on a format they're not designed for doesn't make them a fashion statement. Your choice of use may be a style preference but that doesn't mean the design is only a matter of style.
