I bought this for my husband last year as I can't stand seeing him suffer with red eyes, runny nose and scratchy throat all summer. He was deeply sceptical, but humoured me and put it on before embarking on cutting the grass on a very warm day. Not an itch or runny nose to be seen. He took it off at teatime while we had bbq thinking it must have been lower pollen than he thought only to start rubbing his eyes 10 mins later. He put it back on and it stopped. I'm buying another one for him this year cos he's worn the other one out. Better to wrap something round your arm than put drugs into your body.
