Someone who is going to be wearing readers while handling heavy machinery will likely choose a different lens type than someone who works in an office setting. No matter how you use you readers, there is an option for you!

Lens Materials

While prescription glasses have several different lens material choices, there are two main options for non-prescription reading glasses:

Plastic Lenses

Plastic lenses, also referred to as acrylic lenses, are the most common lens material for over-the-counter reading glasses, and are known for high visual clarity. Plastic lenses are a much more affordable and lightweight alternative to glass lenses, which are used infrequently because of their weight and fragility.

Polycarbonate Lenses

Lightweight and impact-resistant, polycarbonate lenses are used in safety glasses with an ANSI Z87.1 certification, as well as some reading sunglass and rimless reader lenses.

Reading Glasses Lens Types and Uses

Bifocal readers have unmagnified lenses which also contain inserts with the magnification of your choice in the lower portion of the lenses. This type of lens works best for those who are constantly switching from looking down at reading and writing materials to up and off at a distance.

Fully magnified lenses have the magnification of your choice throughout the entire lens. This lens type is commonly worn by those who prefer to only wear their readers when they’re engaged in a task.

Blue light filtering reading glasses provide your eyes with the magnification you need to see the screen clearly, while filtering blue light and glare from your computer screen. Learn more about blue light glasses and their benefits.

Reading sunglasses, also known as SunReaders®️, are readers with tinted lenses to provide UVA/UVB protection for your eyes. Reading sunglasses are available with bifocal or fully magnified lenses and are perfect for any outdoor activity!

Polarized reading sunglasses have the added benefit of a polarized lens, which reduces the sun’s glare and gives you a crisper view. Polarized reading sunglasses are commonly used by those who will be on the water, but they are also a great option for anyone who will be outdoors where the sun’s rays will reflect off of a solid surface.

Reading magnifications above a +4.00 are considered a high reading power and are hard to find in non-prescription reading glasses. Readers.com™ is proud to carry readers up to a +7.00* to help you see more clearly.

Disclaimer: All references to “bifocals” herein refer to readers having unmagnified lenses containing a “bifocal style” single powered reading glass insert located in the lower portion of the lenses.

*Some states have restrictions on the sale of certain reading glasses power and lens types.

How Do I Know If I Need Reading Glasses?

Sometime after the age of 40, you may notice that your vision isn’t what it used to be, but you can still see relatively well. Then one day, the menus at restaurants are a bit blurry and you find yourself squinting. Your eyes feel strained at the end of the day, and you find yourself holding your phone out at an arm’s length to read your text messages. Does this sound like you?

These are some of the most common signs and symptoms that you may be developing presbyopia, the clinical term for what happens to your eyes as you age, creating the need for reading glasses.

Between the ages of 40 and 65, most people’s eyes go through a change that leads to presbyopia. The eye’s lens, which contracts and expands thanks to the help of a circular muscle, becomes less flexible and more rigid over time. This hardening of the lens prohibits the eye from contracting to focus on close-up objects, which is what causes fuzzy vision when trying to read.

Although this may sound frightening, everyone develops some degree of presbyopia during their life, and a simple visit to your eye doctor for an eye exam can confirm the diagnosis. Luckily, there are several easy fixes to correct your reading vision! The most common solution is wearing a pair of reading glasses, also referred to as “readers.” The Vision Council’s VisionWatch Report states that 26.2% of American adults aged 45-54 currently wear reading glasses — you’re not alone!

Finding Your Reading Glasses Power

If you’re going to be buying and wearing reading glasses for the first time, you’ll find the words “reading power,” “reading strength,” “reading magnification,” and “diopter” used interchangeably – they all mean the same thing. When it comes to reading powers, the lower the number, the less magnification there is in the lens. At Readers.com®, we carry powers +1.00 to +7.00, including quarter powers (+.25 increments) and half powers (+.50 increments) so you can get the reading power you need.

There are several ways to determine which reading power is right for you:

Current Eyeglass Prescription

At your annual eye exam, ask your eye doctor what reading power you need.

Power Finder

If you have a current reading glasses prescription with the “ADD” power listed, use our Power Finder Tool to determine the best reading power for you. You can also use this tool if:

• You have a pair of readers that used to work for you, but now things are a bit blurry and you believe you need a stronger power.
• Or to get an estimated reading power based on your age range.

Printable Diopter Chart

This printable chart can be used as a guideline to determine the best reading power for you. If you can see two lines equally clearly, choose the lower power. The chart goes up to a +3.25 power, so if your vision requires a stronger power, we recommend visiting an eye doctor to find your reading power.

How to Buy Reading Glasses

Beginning your search for a pair of reading glasses may seem daunting, but if you know the answers to the following questions, you’ll be able to find the perfect pair of readers in no time!

What Reading Glasses Lens Type Do I Need?

	Bifocal readers have unmagnified lenses which also contain inserts with the magnification of your choice in the lower portion of the lenses. This lens type is perfect for those who prefer to wear their readers all day, or who look from their reading to distance vision frequently.
