I have seen a lot of random capitalisation like this, and I doubt it has anything to do with native language. But I will not say any more, as this may not be considerate towards Jason. I admire anyone who makes an attempt to communicate in a language they have not fully mastered.
@Jasonn You seem to want reassurance that the EM method will work for you, and that you can achieve 20/20 vision. No-one can guarantee this, but it has worked for enough people that you can afford to give it a try. My first bit of advice is that you learn to measure your own eyes, and you can find out how to do so on the website and the forum. You will also find a Snellen chart useful, and you can print out one yourself, although commercial ones are usually of a better quality. This costs nothing other than some searching and reading. Once you know what your actual diopters are (it may be more than -2.5 if you are just assuming it has not changed over the past years) you can start thinking about what would be good for you as diffs for long hours of screen work, rather than making a wild guess as you seem to have done.
