I've come to the conclusion that my helmet issues (see thread 'recommend a helmet' ) are mainly due to stray light entering round the back of the helmet and causing reflections internally on the auto lens and my glasses.
Short of duct taping a set of curtains to the back of the helmet are there any more 'professional' aproaches to blocking the light?
