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).
Why Does The Optic Shop Require Prescriptions?
This is a very frequent topic in e-mails and the forum, and often the cause for frustration: Optic shops require an optometrist prescription for you to get glasses. There is a large degree of arbitrary enforcement of this rule. For one, it depends on the locale you live in. Some areas are more strict than others about prescription requirements. A good idea is to look around and find an optician who is willing to prescribe you lowered prescription per your [...]
Why Progressive Lenses Are No Good For Myopia Rehab
Progressive, not the shortcut you may be hoping for.
Claire: Prescription Reduction Timing
Claire asks, in the forum:I’ve had a -1.75 prescription (reduced from -2.25) for about 2 months. I did one month of the program and plan to do the 2nd month but for the moment I am just using what I learned from month 1 about focus pushing while reading, lots of breaks, outdoor walking.My question is, when you have a reduced prescription, are you supposed to wait until it becomes constantly blazing sharp to reduce it again? With this -1.75 [...]
When Contact Lenses Are The Better Choice
If you follow this blog, you may already know my general opinion about contact lenses. As a matter of a simple yes or no, you will usually hear me say 'no' to the contact lense. First though, on the positive side: Contact lenses do serve well as a task specific solution. For sports, or specific activities not ideally suited for a frame on your face, polycarbonate to get dirty, sprayed with water, or fogged up, the contact lense is appropriate. [...]
The Biggest Eyesight Improvement Gains
There is a fairly common theme in many vision improvement programs. They tend to be comprised of exercises (which usually are not effective, long term - as discussed elsewhere in the blog), and often suggest not wearing glasses. From there, I get a fair amount of e-mail from people asking, whether they should indeed stop wearing glasses. To further substantiate the idea of benefits of not wearing glasses, there is feedback of great improvements, from participants even here, in [...]
Do You Need High Index Lenses?
The index question comes up, every so often, in my e-mail and sometimes in the forum. There are several factors to consider, how much you want to spend on lenses. Always keep in mind that higher index = better optical quality (thinner lenses, less distortion) - and lower index, conversely, is always cheaper. First, there is the question of how often you will change your prescription: If this is your first ever prescription change, you may want to keep things [...]
