How to Find Your Reading Power
How to Find Your Reading Power
Choosing the right reading strength does not have to feel complicated. This guide helps you estimate a comfortable starting point for reading, phone use, screens, and everyday close-up tasks.
What Is Reading Power?
Reading power refers to the magnification strength used to help with close-up vision. Reading glasses are commonly labeled with numbers such as +1.00, +1.50, +2.00, and +2.50.
The higher the number, the stronger the magnification. Most people begin needing reading support gradually after age 40 as near vision naturally changes over time.
Start with your age range, then adjust based on reading distance, comfort, and how small the text is.

Not Sure Which Strength You Need?
This quick tool combines age-based recommendations, reading comfort testing, and everyday reading distance guidance to help you choose a comfortable reading strength.
Quick Age-Based Reading Guide
Your age can provide a useful starting point when choosing reading glasses.
Mild support for phones, menus, and occasional reading.
Helpful for reading small text and screen use.
Comfortable for daily reading and close-up tasks.
Useful for extended reading sessions and smaller text.
Provides stronger near-vision support.
Often used for very close reading or small detailed text.
Common Signs You May Need Reading Glasses
If you extend your arms to read clearly, your near vision may be changing.
Menus, labels, messages, and books may become harder to read up close.
Low lighting often makes near-vision changes more noticeable.
Tired eyes, headaches, or strain after reading can be common signs.
Reading Distance Matters
Phones are usually held closer to the face and may require slightly stronger reading power.
Standard reading distance generally works well with normal recommended strengths.
Computer screens are usually farther away than books, so many people prefer slightly lower strength.
The right strength should feel clear, relaxed, and natural at your normal viewing distance.
How to Choose Lower or Higher Strength
Lower Strength May Help If
You are new to reading glasses, mainly use screens or computers, prefer a relaxed viewing experience, or only need occasional reading support.
Higher Strength May Help If
You read very small text, hold reading material very close, spend long periods reading, or need stronger close-up magnification.
Progressive Lenses vs. Reading Glasses
Reading Glasses
Designed mainly for close-up reading and near tasks. Simple and convenient for occasional reading.
Progressive Lenses
Provide distance, intermediate, and reading vision in one pair, helpful for people who switch between screens, reading, and distance viewing.
Important Note
This guide is intended as a general reference for reading comfort. It is not a medical eye exam or prescription test.
If you have astigmatism, need different strengths in each eye, experience headaches or dizziness, have trouble with both near and distance vision, or already wear prescription glasses, you may benefit from a professional eye exam or prescription lenses.
FAQ
What reading strength should I start with?
Most first-time users between ages 40–45 begin around +1.00.
Is +2.00 stronger than +1.00?
Yes. Higher numbers provide stronger magnification for close-up vision.
Can I use reading glasses for computer work?
Yes, although some people prefer slightly lower strengths for computer screens because screens are usually farther away.
What if the reading power feels too strong?
If text feels uncomfortable, distorted, or too close, try a lower strength.
Do both eyes need the same strength?
Not always. Some people require different prescriptions for each eye.
Can reading glasses replace prescription glasses?
Reading glasses only help with close-up tasks. If you need distance correction or have astigmatism, prescription lenses may be a better option.
When should I consider progressive lenses?
Progressive lenses may be helpful if you regularly switch between reading, screens, and distance viewing throughout the day.
