The optometry dept at Cranwell not only prescribed Aircrew Spectacles for the older aircrew amongst us - they also gave youe eye a full MOT. I was diagnosed with a very rare and obscure condition during one of these visits, and thanks to them I have regular treatment (at Selly Oak) to preserve my eyesight and my flying cat!
As with self drive to Selly Oak - you can always self drive MT unless you are receiving eye drops which means that you cannot drive after treatment. It takes about 2 hours to drive to Selly Oak from a big base near Lincoln - no real hardship so overnight is taking the p**s somewhat.
That said, I will miss the excellent service that I received at Cranwell - the passing of the optometrist department will be mourned!
