The weird thiing about ^^^this old chestnut is that every cycling cap I've ever owned has blocked my vision more than any helmet visor I've ever owned! And I've owned a
lot of helmet visors; in fact, every helmet I've ever owned from ~1995 up until 2019 had a visor. I find them very helpful for keeping the sun out of my eyes while
not blocking my vision the way a traditional cycling cap does.
Only reason my latest helmet doesn't have a visor is it seems like manufacturers are making their MTB helmets less and less similar to road helmets these days, so they're a lot chunkier, heavier, and offer less ventilation than the MTB helmets you could find 4 or 5 years ago.
