Pro Topic: Centimeter vs. Snellen Measurement for High Myopia Cases

You already know the basics about how to measure diopter equivalents for your eyesight, with the centimeter measurement.   You probably already also know all the caveats here:   Centimeter reflects accommodated vision, which can be different from your true distance vision.   Measurement accuracy is key.  If you misjudge the blur point, your diopter equivalent result will not be accurate.   High myopia / small centimeters create a measurement accuracy challenge.  A very small amount of centimeter change equals [...]

Pro Topic: The Eye Guru’s Take On Plus Lens Use

Improvement stories and e-mails are piling up!  Still though today instead of all the good news stories, I want to cover a bit of my current take on plus lenses.   This, a pro topic.  If you're just starting out, you first want to learn about how myopia happens, how to measure your eyesight, and the basics on how to protect and improve your eyesight.  And of course, don't go monkey around with diopter changes until you know what you're [...]

Eye Strain Awareness: Prevent Pseudo Myopia

Eye strain.  It's what put you on the path to myopia in the first place. It's insidious because you're eyes are like the slow boiled frog.  You don't notice the eye strain as it's been building up over the years.  You were doing really fun things (computer games, books) or really challenging things (school tests or job assignments) and before you knew it, your eyes were already strain habituated.   And also you probably had pseudo-, or near-induced transient myopia. [...]

Pro Topic: Ciliary Spasm Blur Vs. Axial Elongation Blur

This, a pro topic.  Quite a bit of the first month of BackTo20/20 is about starting to get a feel for blur.  Blur and clear vision, and the area in-between.  Getting a feel for how that space between clear and blur isn't set in stone, how you can move that space either passively closer to you (by lots of close-up eye strain) or farther using focal challenge activities.That's key for a number of reasons, not the least of which to give [...]

Pro Topic: Addressing > 1 Diopter Astigmatism For Close-Up

So you have more than one diopter of cylinder correction in your glasses.   Diopters themselves, what the number means and how to track your own, now have one page: diopters, explained. You figured out that for close-up you don't want to be wearing full minus (bravo!), and now you wonder what to do about that astigmatism.  You read me state that less than 1 diopter, you can often just eliminate, for close-up glasses.  But what about if you have more [...]
