Hi all,

Been thinking it's about time I got one of those auto-darkening helmets.
Just a bit concerned about that initial flash that's supposed to trigger
the auto-darken feature. I can't see how it can be fast enough to
eliminate exposure to that first bright flash. Anyone used one? Comments
on their efficacy?

cheers.


they are and they do it fast enough, marvellous bit of kit.
Here is a question, How soon after cataract surgery can I start using
one again?(opp last monday)
