After I got in from work tonight, I went straight to the gym for two hours, as I usually do on a Thursday, having had a mere packet of maltesers to sustain me since lunch. I did my usual intervals, weights etc, and was starving by the time I finished. I stopped off at the chippy cos I realised I didn't have anything in, and proceeded to drive home. I live in a rural area, and my drive home is through twisty dark country lanes. About a mile down the road I realised that I couldn't see properly. In the middle of my field of vision was this spiky edged object, all flashing rainbow colours, refracting and distorting what I was supposed to be looking at. I could just make the road out. I was scared stiff! Eventually I got home and scrompfed down my dinner double quick. I had the TV on, but I couldn't focus on the words on the sky menu. They just kept melting away into mush. I was about to phone NHS direct but my dinner was more important! About 10 minutes after I'd finished eating, my vision came back. It's now normal. How bonkers is that? I can only imagine its because I'd not eaten enough, worked a long day and then done a load of exercise. Anyone else had anything similar?
