How to find the right reading glasses strength for you?

EFE GLASSES | Nov 25,2022

After a certain age (probably around 40), you may find that you need some visual assistance while reading. This is a completely normal phenomenon! And then you need to find a suitable pair of reading glasses for yourself to solve this problem. But readers aren’t for everyone, you need to figure out exactly what strength of reading glasses you need.

Why the right reading glasses strength is important?

Because if the reading glasses with a power you choose that isn’t the right one match for your eyes, you may experience some unwanted side effects, such as: not being able to read clearly, feeling headaches, eyes are easily tired, etc.

You need readers that you can see clearly when you put them on and open a book to read, not readers that make words look a little off or even gives you a headache.

1.Printable diopter reading test card

Diopter test charts have rows of words ranging in text size that correspond to reading glasses' strengths. If you’re purchasing reading glasses online, you can also use printable diopter chart.

Step 1: Put the printed sheet 14″ away, and attempt to read the top line without reading glasses.

Step 2: Continue down the chart until you find a line you can read clearly without your glasses on – this is the diopter (power/magnification) you need.

Tip: Make sure to remove your glasses when you use the diopter test. If you have different vision needs in your right and left eye, simply cover up one eye at a time to test each eye individually.

2.Reading glasses strength

Diopters are the units of measurement that determine the strength of your reading glasses. These are also the units in your standard vision prescription, they tell you how much refractive power is present in the lens. The higher the number, the more powerful your glassesc will be.

Reading glasses always have a + symbol before their power, and they come in a wide range of strengths. (Our store diopters from +1.00 to +4.00.) There is a lot of variability within this range, so you want to make sure you choose the right magnification that works for your eyes.

The diopter level that you need will depend on your specific needs. However, we have a reading glasses power chart available in EFE that can recommend the strength of reading glasses you need based on your age.

reading glasses strength chart by age

If you're around the age of 40 - 45, you may need +1.00 reading glasses.

For age 46-50, you can choose +1.50 reading glasses.

For age 51-55, you can choose +2.00 reading glasses.

For age 56-60, you can choose +2.50 reading glasses.

For age 61-65, you can choose +3.00 reading glasses.

For age 66-70, you can choose +3.50 reading glasses.

For age 71+, you can choose +4.00 reading glasses.

Of course, this chart is only for your shopping guide. Choosing the right reading glasses for you depends not only on your age, but also on your actual needs.

In short, if you have to go to the store to try on different pairs of readers, don’t buy the first pair that seems good enough. You should bring a book or some printed paper, and try on multiple pairs of glasses to get a better idea of what kind of power you need. Or you can also find your right reading glasses strength by contacting an optometrist to test it for you. 

If you want to buy suitable reading glasses online, there are nearly 400 kinds of reading glasses for you to choose from on our website. You can choose any three pairs, but only the price of one pair!
