If you somehow created a very large amount of transient astigmatism, [https://endmyopia.org/plus-lens-therapy-read-this-before-trying/ such as this person who had up to 4.25 D of myopic defocus], you might consider adding some cylinder correction, but only as a last resort. | If you somehow created a very large amount of transient astigmatism, [https://endmyopia.org/plus-lens-therapy-read-this-before-trying/ such as this person who had up to 4.25 D of myopic defocus], you might consider adding some cylinder correction, but only as a last resort. | ||
==What is the difference between astigmatism double vision and endmyopia double vision?== | |||
[[Astigmatism]] refers to a condition that creates [[directional blur]], that when significant enough requires cylinder correction. [https://endmyopia.org/wp-content/uploads/2016/02/hd-astigmatic-blur-vs-myopic-blur.jpg This is what directional blur looks like.] Double vision, there are many kinds of it. For example, astigmatism might present itself as double vision but astigmatic blur doesn't have to have DV. But there can be double vision that's not caused by astigmatism. There's no such thing as EM DV. But there is something Jake refers to called ''transient astigmatism''. Which can come in various forms. Double vision, multiple transparent copies, ghosting, and other things of the sort. When he talks about transient astigmatism he is referring to a transition period that exists while you are making gains. A period where your myopia has improved to the point where things are clear in terms of myopic blur, but you still have some disturbances in your vision. There's really a lot of overlap honestly. Don't take the definitions too seriously. They're just ideas to help you look at what you're actually seeing. Because often people see things, but do not pay attention to how exactly these things look to them. The goal is to get familiar with the nuances of [[blur]]. Because there are many different ways blur can look. | |||
