We met them for a couple of drinks last night - something we haven't done for a long time.
When we got home I had an attack of the zigzag coloured lines. These start off as a small dot in my vision where I can't see anything. The dot slowly expands to a (rather pretty) curved zigzag line made up of flashing colours. I took to my bed.
I feel much better this morning but have a slight, intermittent pain in my head, the usual after effect of one of these attacks. I haven't suffered one of these for 2 or 3 years. They went away when I changed my glasses for vari-focal lenses.
Must be time to go back to the opticians.
