As your eyes improve, you will need to reduce again to maintain that slight blur. These reductions typically occur every 3-4 months, and should alternate between differentials and normalized with 4-6 weeks of adjustment period between changes to your focal plane. It is important to be sure you are ready to reduce and that your measurements justify reduction. Reducing too soon is never a good idea (see [[blur adaptation]]). Ideally, you should be consistently (for a week or two) seeing 20/20 in your current correction, indoors, with reasonably good lighting, on a 20 foot or 6 meter chart. The 20/20 doesn't need to be ultra sharp, remember being able to identify half or better on a line is a pass, but make sure you are only giving yourself credit for letters you can actually see; preferably without [[active focus]]. | As your eyes improve, you will need to reduce again to maintain that slight blur.

Once your measurements justify that reduction you want to start out with the new correction properly, which is why it is best to perform a "[[zero diopter reset]]". | Once your measurements justify that reduction you want to start out with the new correction properly, which is why it is best to perform a "[[zero diopter reset]]". | ||
