Linux, politics, and other interesting things
This afternoon I had another visual migraine. It was a little different from the previous ones in that it had more significant visual affects and in that it affected the right side of my vision. My central vision was OK, the left side was quite good, but the right side was mostly occluded by bright flashes. Closing my right eye seemed to make it a little better – apparently my right eye was more affected than my left. Previous visual migraines had only affected my central vision.
It happened shortly after going outside and it was a sunny afternoon, so maybe the bright light helped trigger it. The Australian optometrist chain OPSM advertise transitions – lenses that darken when exposes to UV light so they act as sun-glasses when outdoors, this sounds interesting (I don’t want to have prescription sun-glasses as well as regular glasses). However there is one concerning item in the advert – “protect your eyes from dazzling sunlight, harsh artificial lighting and the glare from computer screens“, I don’t want my glasses to go dark when I’m looking at a computer screen (a large portion of my waking hours)!
