[[File:4201648365539 .pic.jpg|200px|thumb|QZ's lens set]]<br />
<br />
I bought 8 frames (exactly the same type) and all the lenses I need back to 20/20. I also asked my lens provider to cut all the lenses for me according to the frame. I learned how to change the lenses by myself. In this way, I want to minimize the cost also the focal plane change due to the change of frames.<br />

<hr />
<div><br />
The '''blur horizon''' (also known as [https://en.wikipedia.org/wiki/Far_point far point]) is the distance to the '''edge of blur''', where objects in the distance start to become [[blur]]ry. This effect is described as the '''diopter bubble''', because diopters are all about enlarging or shrinking the bubble of clear vision that you experience<ref>https://endmyopia.org/troubleshooting-uncomfortable-blur/<br />
</ref>.<br />
<br />
Your blur horizon is primarily affected by the amount of correction you wear relative to the object you are trying to see.<br />
<br />
==How blur horizon is applied==<br />
===Differentials===<br />
[[File:Blur Horizon Differentials.jpg|right|400px]]<br />
'''For [[differentials]], the blur horizon is ''just enough to see the object''.''' <br />
<br />
In most cases, this is a screen. By wearing differentials, you increase your blur horizon just to the point where you can see the screen clearly, but the rest of the world is still somewhat or very blurry without wearing stronger correction. This is perfectly fine and part of the plan - differentials are only meant to correct you for a set distance.<br />
{{clear}}<br />
<br />
===Normalized===<br />
[[File:Blur Horizon Normalized.jpg|right|400px]]<br />
'''For [[normalized]], the blur horizon is''' '''''nearly''''' '''unlimited'''. <br />
<br />
Emphasis on '''''nearly''''' - it is crucial for the blur horizon to be slightly undercorrected and challenging your vision when compared to a full correction an [[optometrist]] is likely to give you. Being slightly undercorrected is perfect, as too much undercorrection will both stagnate improvements and cause you to [[blur adaptation|live in blur unnecessarily]].<br />

==When to reduce lens complexity==<br />
<br />
[[Lens complexity]] is best reduced before getting into the [[low diopters]] range. Ideally, both eyes would be equal before the normalized correction reaches -1.5 [[diopters]].{{citation needed}}<br />

==How to reduce lens complexity==<br />
<br />
'''Make your first reduction or two simple and [[spherical]]. This will teach you the basics of the [[EndMyopia]] methods.'''<br />
<br />
There are two types of reductions:<br />
<br />
* <div>A ''simple reduction'' or ''binocular reduction'' is drop in lens powers for both eyes, simultaneously</div><br />
* <div>An ''equalizing reduction'' or ''monocular reduction'' is drop in lens power for one eye, the eye with greater correction (more negative)</div><br />
<br />
An [[equalizing]] reduction is done to bring the eyes closer to having the same level of correction. Jake said that "...if you do reduce the ratio, you should have at least 2 regular spherical reductions in between."<ref>https://community.endmyopia.org/t/key-to-patching-successfully-reducing-diopter-ratio/333/6</ref> This is not always possible, especially when [[Guide:High diopter gap|high anisometropia]] is involved.<br />
<br />
There are three types of reductions with respect to the power change:<br />
* a 0.25 [[diopter|D]] drop to [[spherical]] power<br />
* a 0.25 D drop to [[cylindrical]] power<br />
* a trade of 0.5 D cylindrical power for 0.25 D spherical power<br />
<br />
'''There are four rules for reducing complexity:'''<br />
# <div>Alternate types of reductions. Have one (Simple > Equalizing > Simple > Equalizing...) or two (Simple > Simple > Equalizing > Simple > Simple > Equalizing...) simple drops between equalizing drops.</div><br />
# <div>Change only spherical or only cylindrical and never both simultaneously.</div><br />
# <div>For an equalizing reduction, change both differential lenses and normalized lenses simultaneously to keep the [[focal planes]] in sync.<ref>https://endmyopia.org/the-diopter-ratio-trap-dont-favor-one-eye/</ref></div><br />
# <div>For a simple reduction, change differential lenses a few weeks after normalized lenses to keep changes to [[focal planes]] to a minimum.</div><br />
<br />
<br />
'''A note on rule 3 and rule 4:''' Keeping focal planes in sync is a higher priority than keeping changes to focal planes to a minimum, thus rule 3 exists.<br />
