Several years ago I developed a twitch in my right eye. At the time I was shooting 100 benched rounds of 22 per day and working on a computer for much of the day. I googled it and eye fatigue was the likely culprit. I eased back the shooting and it resolved. It recently resurfaced after an 8900 mile road trip and a fair bit of iron sight shooting, maybe 50 carefully aimed shots per day. I backed off the shooting, but the has persisted for a couple of weeks now. Still a little short on sleep, but hopefully that will get better soon. Anyone else experience anything similar? I've also developed more floaters an my right eye than left, doc says it is fairly common, but I wonder if years of hard focusing on front sights has contributed?
