EndMyopia Blur and Small Diopter Shifts | Generated by AI

Home 2026.02

I’ll search for information about Todd Becker’s EndMyopia approach and how small prescription changes affect vision when using reading glasses for close work like laptop and phone use.Let me search for more specific information about the perceptible difference of 0.25-0.50 diopter changes in the EndMyopia context.—

Question: When using reading glasses for laptop and mobile phone work with an existing -1.50 diopter prescription and following Todd Becker’s EndMyopia method, do small differences like ±0.25 or ±0.50 diopters create significant and noticeable blur?

Answer:

No, small prescription changes of ±0.25 to ±0.50 diopters are not significantly noticeable in most cases, but the perceptibility depends heavily on your baseline prescription and how the method is applied.

Key Findings from EndMyopia Research

The same 0.50 diopter reduction has a very different impact depending on your baseline prescription. For example, going from -9.00 to -8.50 is only a 6% reduction, while going from -2.50 to -2.00 is a 20% reduction. Therefore, 0.50 diopters affects different myopes differently based on their starting point.

Perceptibility at Your Current Level

For someone at -1.50 diopters specifically:

Variances under 0.50 diopters may not be noticed by most people. Changes of 0.25 to 0.50 diopters are considered minor and normal, and many people can continue wearing their old glasses comfortably with such small changes.

The EndMyopia Context: “Edge of Blur” Principle

This is where Todd Becker’s method becomes important. In the EndMyopia approach, you minimize the prescription to where you can only see as far as your comfortable ergonomic viewing distance—whatever distance you are from your computer screen. Beyond that primary distance, you want to encounter some blur in your vision, which is absolutely key to the practice.

The goal is not to have perfect clarity throughout your visual field. Instead, the idea is that you reduce your prescription to where everything past your working distance (such as 55-60 centimeters) begins to look blurry, providing the positive stimulus needed for vision improvement.

Practical Application for Reading Work

When reducing your prescription gradually for close work:

At below two diopters and only 0.25 diopters difference in otherwise healthy eyes, it’s a close call whether the difference is noticeable. You need to ensure both eyes remain challenged and participating. Typically, anything more than 0.25 diopter difference between left and right eyes is considered too much, and you should wait at least two to three weeks with good distance and focus-pushing habits before making additional adjustments.

The Critical Difference from Standard Vision

The EndMyopia method is fundamentally different from conventional eyewear use:

When using full minus prescription during close-up work for eight hours a day, this is very problematic and leads to lens-induced myopia. However, by using a reduced prescription that allows blur to appear beyond your working distance, you eliminate the lens-induced myopia risk while providing positive stimulus for vision improvement.

Summary

Small 0.25-0.50 diopter differences alone are not noticeable for general vision clarity. However, within the EndMyopia framework, these differences matter because you’re intentionally working at your “edge of blur”—the point where your screen is clear but distance vision becomes progressively blurry. The goal is not comfort, but creating a stimulus for natural vision improvement.
