Lens Power

What is Lens Power? Lens power (also called magnification strength) tells you how much help the lenses give your eyes to see things up close. It’s measured in dioptres (D) and for reading glasses comes in + (positive) numbers.

How It Works: 

+1.00 to +1.50: Great if you’re just starting to need a little help with small print.
+2.00 to +2.50: Ideal for more noticeable reading struggles or longer reading sessions.
+3.00: Best for strong magnification needs or serious close-up clarity.

✔️ do your arms feel too short when reading?

✔️ are you squinting at your phone?

✔️ trouble reading labels and recipes?

✔️ headaches after reading or after screen time?

✔️ do you feel like you need computer readers?

That usually means it's time for readers! Try starting with a +0.5 or +1.00 or and adjust based on comfort.

💡 Pro tips

💡 You can test different powers with printable reading diopter charts online - or try a few at a local retailer and see what feels best.

💡 You might be able to determine which strength of reading glasses you need by consulting a "lens power by age table" like this:   

Age 40-44	Recommended power +0.5 to +1.0
Age 45-49	Recommended power +1.0 to +1.5
Age 50-54	Recommended power +1.5 to +2.0
Age 55-59	Recommended power +2.0 to +2.5
Age 61-65	Recommended power +2.0 to +3.0

 

💡 If you’ve narrowed it down to two pairs of readers, it’s usually best to choose the one with less magnification.

💡 Non-prescription glasses are designed to work for reading or looking at other things up close, and if you are using them to see far away you should visit your local optometrist to discuss this.

💡 Note that a stronger lens is not always better, so reconsider a lens power that allows you to read something at a comfortable distance.

💡 You might find that you require different lenses for various tasks. If so, have a think about buying several pairs of reading glasses, each with a different strength of lens.

💡 If you’re using reading glasses mainly while on the computer, perhaps choose a lower reading glass power. A lower reading glass power should be used when the viewing distance is longer. A lower strength of our reading glasses work great for computer readers. Keep a pair next to your screen.

💡 If you're wearing reading glasses to see objects that are very close or very small, you will need stronger strength lenses with higher magnification than what the age-based reading glasses power chart might recommend.
