I have always worn a full face helmet, but have not had problems with glasses staying put. The helmet pads are snug against the eyeglasses frames by my ears and hold them in place. The pressure is very gentle and not at all uncomfortable. If I wanted, I could ride with the eyeglasses frame bridge hovering just above my nose and not really touching it.Thegoat said:For the first time i now have to wear glasses for driving/riding and have trouble with them slipping down during riding. Has anyone any tips to prevent this happening. I use a full face helmet so have to put on glasses with helmet already on.
