How to Buy Prescription Reading Glasses Online
Ordering prescription reading glasses online is convenient and often far cheaper than a brick-and-mortar shop. But a few details matter. Here's exactly what you need before you order.
What You'll Need
- Your prescription: including sphere (SPH) values for each eye, and your pupillary distance (PD).
- Your PD measurement: ask your optometrist, or measure it at home with a millimeter ruler.
- Your frame size: check the width against a pair that already fits well.
Step-by-Step
- Get an up-to-date prescription from an eye exam (recommended every 1–2 years).
- Note your PD in millimeters — this is essential for lens centering.
- Choose a frame that suits your face shape and daily needs.
- Enter your prescription values exactly as written.
- Double-check your order before submitting.

Frequently Asked Questions
Can I order reading glasses online without a prescription?
Yes, if you only need magnification for near work and have no astigmatism. Choose a strength by testing the diopter chart or using the strength printed on an existing pair. If both eyes differ or you have astigmatism, get a prescription first.
What information do I need to order prescription glasses online?
You need your sphere power for each eye, cylinder and axis if you have astigmatism, pupillary distance, and optionally an add value for progressive lenses. Your eye doctor must provide these after an exam, usually as a written prescription.
How do I make sure online glasses fit properly?
Compare the frame width and temple length printed on your current glasses with the product specifications before ordering. Most brands list lens width, bridge, and temple length, and matching those numbers prevents most fit problems.
Can I use my last prescription to order new glasses?
Usually yes, if it is under two years old and your vision has not changed. Beyond that an updated test is worth it, because small shifts in sphere or cylinder are exactly what make new glasses feel wrong.
What if my two eyes need different strengths?
Ready-made readers cannot do that, because both lenses carry the same power. You need prescription lenses ground separately for each eye, and the price difference is smaller than most people expect.
