Wow, thank you for that reply!!
I do want to see an eye specialist to see what they say and was thinking of trying to get an appointment with a specialist RAF optician.
As a university student, sleep is certainly not something I get a great deal of, late nights are the norm. Im trying to get early nights now to see if that does change the astigmatism. I would not say that in my day to day life I am stressed, but the general situation with my eyes and how it is affecting my career is I suppose causing a high degree of tension, and it is something I think about everyday.
Im going to see a someone who teaches you how to relax your eyes (based on the Bates method) in a couple of weeks. Thougt that would be worth a try!
I am convinced by the varying degree of astigmatism having noticed no change in my day to day vision that it is environmental. The problem is Im not sure whether, even if I proved this to the RAF they would consider me for pilot. Do you think when I go for selection again I should take my prescriptions and explain to them how I dont think it stays at a constant angle?
If you know of any good specialists I would be very grateful! Thank you for your advice you have already offered me though!
