My 38 year old son is working in Turkey at present and has reported having daily headaches and blurred vision, even when wearing glasses
marking a swift deterioration since his last eye test which was in mid August 2011 when his peripheral vision was fine and his vision 20/20 with the glasses prescribed.
Lately, his vision, even with his glasses, is always blurred with some blotchiness making some areas darker than others and he now has little peripheral vision, it seems.
He finds it hard to focus on objects and the printed word making reading a strain after a short period.
Occasionally, he reports little circles drifting across his vision.
Along with the eye test, he had an IIRC on his retina which disclosed some minor debris behind the left eye.
The symptoms are exacerbated by bright light so he wears prescription sunglasses
It should be mentioned that he had an eye straightening (squint) operation at age 7 which had no negative results.
As he is not currently in the UK, it would be helpful to know who he should approach to have his symptoms checked out and what, if anything, he could do to alleviate them in the meantime.
