For several weeks I too have been having eye trouble, which is partly due to heat and very bright sun, but also due to toxic smoke from forest fires. We now have two closer fires burning only ten miles from here, and lots of smoke, so I am inside with a filter most of the time.

A year ago I was evacuated, as was most of the town, because of fire and smoke threat.
It may happen again. Living here may become impossible.

I recovered pretty well from last summer's onslaught, but eye remained weaker.

My symptoms are mostly what I think may be nystagmus, eyes moving L and R, and up and down, and even seeming to go clear out of my upper field of vision. Very painful, feels like a spasm. I am not having double vision at this time, as I did in my optic neuritis bout decades ago. Just fizzy vision and light sensitivity so that using the computer is a marginal process...have to ration time on the computer.

Yes, light is part of the problem, and I wear a Solumbra hat when going out, plus dark glasses, and have tinted windows in the car, which is necessary because of living in a sunny climate. I also wrap my neck and head in a Solumbra scarf, from Sun Precautions. But just the heat we are having now, apart from the light, is getting to me.
