Diopters. We stopped calling glasses “prescriptions” a while back, since we don’t believe a reasonable educated individual needs a so-called professional to tell them which piece of clear, curved piece of plastic to buy. (or conversely, keep you from making your own diopter choices)
If anything, we believe that most of the mainstream will give you more diopters than you need, causing progressive myopia and all sorts of long term risky side effects. We feel strongly about education you on the subject of testing your own refraction, of making your own diopter choices. Glasses are far less dangerous than lots of over-the-counter drugs! Read this section for all things related to diopters, learn about the fascinating world of bending light (to your will).
Optometrist Confirms: Astigmatism Is GONE!
File this under the category of "impossible", if you're an old-timey lens prescribing type of optometrist. Perhaps we should rebrand the site as some kind of school of wizardry sometime soon, considering the years and years and hundreds of students reporting these kinds of "impossible" results, and considering how all of this can't even be done. Old-timey optometry, vs. Jake's school of endmyopia wizards. Round 5917, posted today in the forum by Val: Hi Everyone, I just got back from [...]
Contact Lenses For Distance Vision?
A few days ago, in the frozen wasteland that is Tokyo in February, I recorded a quick video on the subject of contact lenses for distance vision use. It's a continual somewhat tenuous relationship, me and contact lenses (I never used them personally, but for the subject of myopia control). They have lots of notable advantages, for a number of use cases, but then they are also not ideal for long term vision health, and another temptation to take the [...]
Astigmatic (Cylinder) Blur Vs. Myopic (Spherical) Blur
The plan for today was to tell you about a big glaucoma study in Singapore. Interesting stuff, and it very seriously applies to high myopes and possibly will bring much earlier detection to a particularly insidious form of glaucoma. Alas ... that one will have to wait. Something popped up in the forum today that I want to share with you, before it gets lost in other topics. Boris describes the difference between astigmatic blur and myopic blur so perfectly, [...]
Vision Improvement: Should You Start Wearing Glasses?
Let's dive into the forum a bit today, for interesting stories. I feel that regular blog readers miss out on some of the most insightful and intriguing experiences by not having access to the forum. To rectify that at least occasionally, look for various highlights and excerpts here in the blog.Toshiki writes:Hi, my first day on the program – yeay! And even though that’s at the fourth method I’m trying in the course of only five months (1st: Bates, 2nd: some [...]
Cycloplegic Refractions & Avoiding Early Myopia
"A cycloplegic refraction is performed as a part of a laser visual correction,or LASIK, consultation to determine the absolute refractive error before before proceeding with laser eye surgery." A cycloplegic refraction is an eye test performed by an optometrist after the instillation of drops which will temporarily paralyse the ciliary muscle, preventing the eye from accommodating and constantly changing prescription. This prevents over-prescription in these cases, ie. too much minus in a prescription, giving a more accurate result.Under normal conditions, an experienced [...]
A Fun Way To Quantify Overprescription For Yourself
Kellee posts an interesting experiment in the forum. As a bit of background on this, she went to the optometrist, who gave her a much higher prescription than her own centimeter measurements would suggest. Confused about this, she went home and did this:Neat, right?You can just convert the optometrist prescription numbers back to centimeters, and then see how clearly you can see at that exact distance.Everything is pin sharp, no matter the ambient lighting? Stays sharp even if you move [...]
