Helmets with an Optically Correct Visor
An optically correct visor means there’s little to no visual distortion when you look through it. Most visors are pretty good to be honest, because their visor distortion is controlled by the ECE certification process before they’re put on sale. So I don’t think many of us are too troubled by distortion when we’re riding. But if you want the very best clarity on your visor, you might want to buy one of these helmets.
Here’s more information about optically correct visors and on these pages, you’ll find motorcycle helmets that come with an optically-correct visor (or have one available).
