hi, i too have been having problems with one eye, for about three years now i guess.
i searched the net and found your postings. i'm not sure why it happens. i'm training to fly helicopters so am very worried if it will cause problems later and stop me flying!
Its always my right eye and seems to happen after i get myself stressed with study or don't sleep well and am tired and get the feeling my eye is 'sore'.
I used to work with computers (for 10 years), and believe this made my eyes generally oversensitive to bright lights and computer screens and normally i can find bright lights in the lounge or out in a bar too intense.
just to put you girls at rest i guess its nothing 'female' like the pill or period stuff..
sounds like it might just be 'cluster headaches'..but i don't really get headaches even with stress, and this has only come on all of a sudden in the last three years or so.
had full eye check when applied for medical class one certificate the other month and eyes seemed fine...i forgot to mention this at the time as hadn't happened for a while.
wierd...!
