I wouldn't trust your optitican, the only way ull find out if u can pass is by going down there and getting examined. Mr Chorley is the man who does it I believe.
Went to my optician back in 2000 to see if I met the requirements, he told me I didnt and that I was wasting my time. Was only in 2005 that I read a thread on here which made me think I was in with a chance, went down to gatters and low and behold, they gave me my medical!
So basically my aviation career is 5 years behind schedule as a result of listening to an optician!
Could have been an A380 captain by now!
