Question 1

How do reading glasses work?

Accepted Answer

Reading glasses are often likened to magnifying glasses in their functionality, though that’s not exactly how they actually work. Rather than simply magnifying, reading glasses are designed to help your eyes focus more clearly on things you’re viewing close-range.
The strength of glasses lenses is measured in number units called diopters. The numbers in the measurements have a plus or minus sign in front of them. That plus sign means the lenses have a higher strength and will boost your eyes’ ability to focus on things closer to your eyes. Most reading glasses fall into this category, and if you need them you’re probably farsighted.
A minus sign means the lens strength is decreasing and will boost your ability to see things farther away from your eyes. Most nearsighted people have lenses like this.

Question 2

How do I know what strength reading glasses to get?

Accepted Answer

Most people wear reading glasses with a strength between +0.75 and +2.50. The best way to pick reading glasses that complement your vision needs is to consult an optometrist.
That said, our guide to reading glasses strength includes a chart you can use to test yourself at home. Keep in mind your reading glasses will likely need to increase in power as you age.

Question 3

Are reading glasses FSA eligible?

Accepted Answer

Yes, reading glasses are FSA eligible. At Warby Parker, as long as your FSA account is affiliated with a major credit card, we can also accept FSA payments for the following: contacts, prescription sunglasses, prescription eyeglasses, and eye exams.

Question 4

Are reading glasses the same as “seeing” glasses?

Accepted Answer

The short answer is no. Reading glasses aren’t meant to be worn all the time. They’re specifically designed to help you see things close up.
Prescription glasses can correct vision problems reading glasses aren’t meant to fix, like astigmatism or farsightedness. They’re also designed to be worn all day, including for everyday activities like driving.

Question 5

Do I need to go to an optometrist for reading glasses?

Accepted Answer

We recommend going to an optometrist to ensure you get the right strength of reading glasses for your eyes. That said, you can order reading glasses without a prescription.

Question 6

Can you wear reading glasses all day?

Accepted Answer

Technically, you can wear reading glasses all day without risking long-term negative effects on your eyes. However, doing so may cause headaches and eye fatigue, so it’s not recommended.
