I’ve changed things over time after feedback and new insights. This guide right now actually I’m in the process of replacing with something else. The stuff about using your center of vision should still be here though. Thanks for your interest!

If you mean the sun treatment that Bates did, the patient would have his eyes open, but looking far down so the sclera (white) of his eye is exposed, and Bates would use the magnifying glass to wiggle the focused rays across the sclera. I don’t remember how long he would do it for, and I don’t know exactly how sharply he focused the rays and things like that, but he might go into more detail in the Better Eyesight magazines.
