Well as someone has mentioned before you cannot join the RAF if you have had laser surgerey. How strong are your glasses anyway? 20/20 is perfect what are your eyes at? I also wear glasses already
, but they are to stop my eyes straining when looking at small font. For example if i used the computer for an hour my eyes would begin to ach. I can still read things at a distance, but if they are small my eyes strain. So the glasses remove the strain, i assume this isnt a problem, of course if it is someone please tell me now!
