Eye fatigue and losing your place while reading might be an eye-tracking problem, not a vision problem. Bill Daniels shows a 10-second test: focus on your thumb a foot away, then a distant target, back and forth as fast as you can. If you can't keep up, your eyes need tracking work.
If your eyes get tired while you're reading or you lose your place easily, or even if you get headaches after screen time, it might not be a vision problem. It might be an eye tracking problem, and we can fix that. The first thing we're going to do is we're going to test your eyes. So here's what you need to do. You need a target off in the distance. I'm going to use the camera, and then you need a target that's close. We can use our thumb. What you're going to do is bring that thumb close to you where you can still see it clearly. So as you can see, it's about a foot away from my face. My second target's directly behind that, and I'm looking at the camera. I'm going to look at my thumb, see it clearly, then I'm going to look at the camera. Once I see that target clearly, I go back and forth as quickly as I can, but without ever jumping before you see the target clearly.
