TBH, I am wondering if my "new" opticians made an error. I recently changed from Boots to Spectsavers. The person that examined me said that glasses will do very little to improve my left eyesight, and that I won't be accepted anywhere in the military. This is why I called the RM's.
When I was with Boots, this never came up. They said it was possible for me to pass the RM examination. BTW, I was also very tired when I went for my last examination. I wonder if this could have affected my results  
 
 
I really don't want to cheat the eye examination, but if it's the only thing that is going to let me down, I see no other choice, especially when, in a pratical sense, my eyesight seems perfectly fine. I have never experienced any problems when not wearing glasses (never worn glasses).
Anyway, thank you for your advice so far guys
