View # When someone is watching your hubs without your adsense ads.
Impression # When someone is watching your hub and also your adsense ads are appearing..
Note that # Your adsense appears besides your hubs only on 60% of your hubs viewing.And the rest 40% ads are of hubpage itself..
That mean # If 1 of your hubs get viewed for 10 times than 6 times will be counted as the impression and the rest 4 times as a viewing..
Keep in mind that # Viewing does not give you any doller.
NB # If you more about this matter just PM me.
