If you are ordering standard reading glasses, no prescription is required. You can choose your magnification strength by using our printable reading chart or the general age-based guide below.
For best accuracy, print the chart at 100% / Actual Size on US Letter paper. Do not scale or fit to page.
| Your Age | Recommended Reading Glasses Power |
|---|---|
| 40–44 | +0.75 to +1.00 |
| 45–49 | +1.00 to +1.50 |
| 50–54 | +1.50 to +2.00 |
| 55–59 | +2.00 to +2.25 |
| 60+ | +2.25 to +2.75 |
If you are between two strengths, we usually suggest starting with the lower strength unless you already know that you prefer stronger reading glasses.
Please note that reading glasses are mainly designed for near vision only. They are not suitable for distance vision, driving, or correcting complex prescriptions such as astigmatism. If you already have an eye prescription, please follow your optometrist’s advice.
No. Standard reading glasses use a simple magnification strength, usually the same power for both eyes, and are mainly designed for near reading.
A prescription may include different values for each eye, such as SPH, CYL, Axis, ADD, or PD. If your prescription includes astigmatism correction or different powers for each eye, please choose prescription lenses instead of standard reading glasses.
Weight: If you want an ultra-light frame, choose a frame that is 16 grams or less. Titanium frames are generally very light.

Flexibility: This is a great feature for kids or sports glasses.
Color: Acetate frames tend to be available in more colors.
Hypoallergenic: Titanium and acetate frame is hypoallergenic.
How to Measure Your PD?
- Stand 8 inches away from a mirror.
- Hold a ruler against your brow.
- Close your right eye and align the ruler’s 0 mm with the center of your left pupil.
- Look straight, then close your left eye and open your right eye.
- The mm line that lines up with the center of your right pupil is your PD.
