Your [[Normalized]] and [[Differentials]] [[Lenses]] power should steadily reduce in power over time. (+0.25 for myopes, -0.25 for hyperopes, moving towards 0) ~~Meaning your~~ correction should be a quarter diopter weaker than ~~what you need~~ to see clearly ~~and this~~ provides a slight [[blur]] stimulus for change.

Your [[Normalized]] and [[Differentials]] [[Lenses]] power should steadily reduce in power over time. (+0.25 for myopes, -0.25 for hyperopes, moving towards 0)

Generally, the [[correction]] should be a quarter diopter weaker than needed to see clearly, which provides a slight [[blur]] stimulus for change, although trading 0.5 cyl for 0.25 [[spherical equivalent|sph equivalent]] is also possible.

This can be generalized to alternating a gap of <code>G-0.25</code> and <code>G</code>, with these properties:

This can be generalized to alternating a gap of <code>G-0.25 D</code> and <code>G</code>, with these properties:

* Reduce norm at <code>1/G</code> through diff (gap of <code>G-0.25</code> for first half of norm, second half of diff)

* Reduce norm at <code>1/G</code> through diff (gap of <code>G-0.25 D</code> for first half of norm, second half of diff)

* Reduce diff at <code>1/(G-0.125 D)</code> through old diff, <code>1/(G+0.125 D)</code> through new diff (gap of <code>G</code> for second half of norm, first half of diff)

* Norm always has 0 to 0.25 D of undercorrection.
