The title of this post points to something interesting: If you can read 20/20 with a -4.00 prescription (after a month or two of basic efforts) why did the optometrist prescribe you a -5.50?
Consider, that’s almost a 30% higher prescription than this individual needed to see 20/20!
It is an interesting thread on the subject of prescriptions and active focus in the support forum, created by Can (link below).
It is a fairly common scenario, one that most new participants will encounter. There is always the question of how much of a reduction you want to start with, to get the most stimulus opportunity, while still enjoying clear vision. And since there is no single answer that fits all scenarios, I maintain the support forum to address your individual questions on the topic.
Here is a reason to read Can’s discovery process, though: It highlights the need to follow the basics of the process, of learning to measure your vision, keeping a log, and taking the leap to a first prescription reduction.
You learn a lot from this process. That first prescription reduction puts all the pieces together, allowing you to assess the difference in your vision with it, and find out how much some targeted stimulus will improve your eyesight. It’s a very simple process once you have done it once. It gives you the skill set to analyze your own vision deficiencies, and confidence in repairing your healthy eyesight through first hand experience.
The fundamental premise of this site is to give you a clear understanding and control over the use of prescription glasses.
Many optometrists obscure the process and leave you with just the final product – which amounts to a short term fix and a long term compromise to your eyesight health. If you commit to 20 minutes a day, three times a week of learning, in a matter of a month (or two), you will have all the knowledge you need for a lifetime of healthy eyesight.
It’s only daunting until you try it. For some inspiration, take a look at Can’s forum thread here.
Enjoy!
