What Strength Reading Glasses Do I Need?

If you have started to notice that up-close reading is challenging, it might be time to try reading glasses. Reading glasses can mean the difference between having a tension headache at the end of the day or feeling fresh and fit. In this guide, we’ll help you determine what strength reading glasses you need and how to pick out the perfect pair for you.

How Do I Know If I Need Reading Glasses?

Reading glasses are non-prescription, meaning you don’t need to see an optometrist to start wearing reading glasses. While you should still get regular check-ups on your eyes to make sure they’re healthy, there are a few signs you may notice on your own that indicate you need reading glasses: 

 You find yourself squinting when you read

  • Words are starting to look blurry
  • You hold menus or mail farther away from your face when you read it
  • You have a headache after spending a few hours on the computer

What Do the Strengths Mean? 

Reading glasses are measured in diopters. The magnification of reading glasses ranges in strength from 1-3 diopters, increasing by 0.25 diopters, and you’ll sometimes find reading glasses higher than 3 diopters in strength. 

The higher the number, the higher the strength. So, +1.25 reading glasses would be less strong than +1.50 reading glasses, which would be less strong than +1.75 reading glasses.

How Do You Know What Strength Reading Glasses to Get? 

If you’ve had reading glasses in the past and they’re not working as well as they used to, you can pretty safely increase the magnification of your reading glasses to improve their functionality. However, if you’ve never had reading glasses before, you may have no idea where to start. 

There are a few different ways you can estimate which magnification you need for reading glasses. 


Estimating Reading Glasses Strength by Printable Test

Printable diopter test pages and cards are available on the Peepers website that can help you determine the right diopter strength for you. 

The most important thing to know when using printable tests is to follow all instructions precisely. If you print on the wrong size paper or use the wrong dimensions, your results could be inaccurate. It’s also critical that you use a good printer with enough ink, as faded ink or smudged print could alter your results.


Estimating Reading Glasses Strength by Trying Some On

One of the most common ways to figure out the right strength reading glasses for you is to try on a couple of different pairs and see which strengths work best. Always go with the lowest diopter rating that allows you to read comfortably. This allows you to scale up if your eyes continue to worsen with age. You can find a list of Peepers retailer locations here to go and try them on in person.


Having Your Eye Care Provider Test Your Vision

Annual eye exams are recommended to monitor your overall eye health, check for common eye diseases and ailments, and reevaluate your vision to ensure you are using the correct prescription. While you can estimate your strength with a fair amount of accuracy by using the printable test or trying on glasses, your safest bet is to have an eye doctor administer a vision test and provide you with the exact numbers. Some people require a different prescription for each eye, and using the wrong strength, whether it’s too high or too low, can strain your eyes and cause your vision to decline faster. If you have any doubts about the strength of your reading glasses, talk to your regular eye care professional and schedule an appointment.
