Apologies if this has been mentioned earlier, believing my vision to be too poor for a class 2 med pass I thought NPPL standards would be less exacting, asking the optician if I would pass the minimum uncorrected DVLA professional driver requirements It was proved NO, Yet checking the CAA website you can fly with a prescription of up to -8 dioptres of correction with no uncorrected limit. Have I read this right? Thanks in advance for replies!
