This is a pointless argument. The CAA have provision for just theae sort of cases.
Not really, what happens when your eyseight is below the revalidation criteria? My eyesight is approx -9 LH and -10 RH yet is corrected to 6/4 and is refractually stable and has been for more than 3 years. For me this is a pointless argument as I no longer care to fly but for many others it is an issue that really ought to be revisited.
