Easy226,
On the wider subject of aircrew eyesight standards, there was an earlier thread on the topic which might be worth you searching for - basically it said the Navy have a slightly lower eyesight standard, and so if you're a borderline case you could be accepted by the RN even if you're below the RAF limits.
For civilian flying you can wear glasses from the word Go, which is worth bearing in mind if you are rich!!
In any case, good luck at the selection day.
