I wear spec's now for road riding with my Arai X4, but not with my Arai RX7 due to lack of space although I can just squeeze them in should I wish. Track riding & trials riding, plus looning around on my Bonnie with an open helmet I do not wear glasses. So I don't need glasses to see where I'm going, but I do if I need to read the dash or sat nav at a glance - same in a car.
I did try a Shoei Neotec flip up thing with an inbuilt Senna intercom when I got my last GS new in 2020. I hated that helmet so much that whilst up in Scotland I wanted to simply throw it away and go buy a cheap one just to get me home. Luckily perhaps there weren't any helmet shops up on the North coast and into Syke so I brought it home with me never to be worn again.
Why? Because the internal sun visor, plus spec's & plus the main visor (can't remember if it had a pinlock..) meant that the optical distortion & light actually getting through were both dangerously poor - for me. The intercom/sound was totally hopeless & maybe this is linked to the OP question about noise...
I have for as long as I can remember always worn an Arai (did have a Lawson Shoei road helmet in the '80s to match my LC) & that quality you get used to. The Shoei felt cheap & not safe, so that and the crap visuals meant I got rid plus the flip up chin bar was flimsy.
There is a reason that Arai do not install an internal visor & that's because they won't compromise on safety.
As soon as the new Arai Tour X5 is available in colours & in size Large, I will have one immediately (awaiting my 'in stock' email from Sportsbikeshop). I find the visor swapping on the X4 a PITA, but the visuals through the tinted/non-tinted visors with pinlock is superb with spec's too. Arai lining, vents etc all top class stuff.
