My astigmatism is on the extreme side. About 20 years ago it was off the charts (before the measurement technology advanced in precision). I have had it all my life and cannot imagine vision without it. I just wear glasses all the time and power through it, even through environmental extremes and long period of high stress activity.
Whether because of my high myopia, the high astigmatism, or the super strong corrective lenses (or other factors) my eye muscles seem to work differently than other peoples'. I seem to have a faster twitch rate (rapid movement between points of focus). I can focus on things for longer periods of time without blinking and I seem to be less prone to eye fatigue and injury than many other people. My eyes do get tired though, and when that happens I have trouble discerning between eye fatigue and mental exhaustion, but at any rate when fatigue creeps in I am done.
