there are some clips on the side of the lid you have to learn how to take the plastic with the scratches off.
then you take it to a shop same day get a new visa and put it on same day or from what i pick up (and it may just be me) you suffer from being blonde, or a few pence short of a note. You'll forget how to put the thing on and it will take a wk to remember how you took the thing off

Or you
think you put it on right, only to find you push it up comeing to the first set of traffic lights only to find it pings out one side and you sit on your bike wondering how best to deal with a helmet where the visor is flapping around like ladybird's broken wing.
... knowing that it's already too late to avoid looking incredibly stupid and giving the bored commuters something to giggle at.
Never happened to me. Not once. Anyone who tells you different was confused by the glare bouncing off their scratched visor.
