Hey There
I can see no real problems, not with the Education for sure, and i am sure not for the vision.
Education for even a sponsorship or ctc is just two A'Levels, C or above, i see you have that, and trust me, thats more than some have. Its more about getting what you need to be a pilot, licence and ratings than what education you have, even though i am sure there are situations where it might help a little.
Vision, same problem as me, i just about passed the stupid DVLA eye test when i did my driving exam, i took all the paperwork from the CAA to my opticians and had a moc test as such there and i was well within the limts for most, not astigmatism though, i was just within the limits of that so its going to be a little hit and miss for me when going to the CAA to get a C1 medical.
Anyway, good luck, and i am sure the vision will be fine...
