How To Find the Right Strength Reading Glasses

by admin on April 12, 2012

Nearly all people above the age of 40 suffer from presbyopia, and thus rely on reading glasses for their close range vision.

Many individuals new to experiencing presbyopia are not only new to requiring readers to focus on close range images, but are new to needing any optical correction at all. Because of this, many people have a hard time finding the right strength reading eyeglasses for their vision needs.

Find The Right Strength Reading Glasses

For those who’ve just recently started to experience presbyopia, the first thing they’ll see when looking for reading glasses are a bunch of tags and labels that read similar to the numbers listed below.

These numbers represent the corrective strength of the individual pair of readers, also known as “Diopters”. Most reading glasses are created in increments of .25 diopters to differentiate stronger and weaker corrective powers, where the strongest power has the highest Diopter Value. For example, someone who needs strong vision correction will likely need reading glasses with a strength around +3.0, while someone who needs only minor vision correction would likely wear reading glasses with a label of +1.25.

For most people new to needing readers, it’s highly unlikely that they’ll need a high powered  lens. Presbyopia like many eye diseases typically starts as a minor vision impediment, and slowly increases as you age.

Reading glasses are rarely manufactured for strengths greater than 4, and typically range from strengths of 1-3. While reading glasses generally don’t need to be as accurate as normal prescription glasses, finding the right size for you is important, as wearing the wrong size can cause headaches, dizziness, or nausea. In order to find the right strength for your reading glasses, take our online reading glasses test to determine the lens strength you need.

Similar to readers, makeup glasses should use the same strength for proper vision correction.

Two Tests to Find the Right Strength Readers

There are two general ways to find the right strength readers for your eyes. Most people figure out what readers they need via a process of trial and error, where they simply try on ready-made readers until their close range vision is clear and acute. While this is convenient at a store, it doesn’t work as well when you do not have a wide selection of readers to try on.

For people who want to find the right strength reading or makeup glasses while at home, simply follow the instructions on our reading-glasses strength test in the image below. They can use the test below to accurately gauge which strength readers they need, eliminating the need to run to a store to find the right size. Click here to pull up the full size image.
