My usual riding around helmet is a Nolan N103; it is OK, but a bit noisy. My glasses stay in place while wearing it, too.
For sport riding and track days, I picked up an Arai RX-Q. The fit is great and it is quiet with good venting. The problem is that my glasses slide down my nose easily. Under the Nolan, there is some padding that holds the temples. The Arai doesn't seem to have the same padding around the ears.
Anyone with the same experience? Suggestions for fixing it?
Don't suggest Lasik. I had that done about 10 years ago. My vision before was horrible; now, I can just pass the DMV eye exam without glasses. Most of the time I go without glasses, even when driving. When riding, I want every bit of clarity.
I have the exact same problem with my Arai Corsair V, my daily helmet. Find for the ergos on my Sprint, but I don't use it at the track for that reason alone - I use my Scorpion EXO-1000 on the track. With the Scorpion, it's harder to get the glasses on, but once in, they stay up on my head, even a little higher than when perched on my nose if I set them that way, which is great for maximizing the scope of corrected vision on the track.
My glasses are perfectly adjusted, but when I'm bending down over the bike on the track, they still tend to slide down - and that's with the little nose pads.
May be a way to adjust the glasses, but mine have the stretchy sides over the ears, meaning if you open the glasses, you can open them extra wide and a spring pulls them back to 90 degrees...maybe they don't hold my head tight enoug.
