CHOOSING YOUR LENS POWER

What Strength Reading Glasses Do I Need?

Your reading glasses lens strength is determined by
- your age
- your reading distance
- if you wear or need prescription eyeglasses for other distances.
01

Estimate Your Lens Power

Age used to be the biggest factor in needing reading glasses, but long hours on computers and digital devices have changed that. Still, this timeline offers a helpful starting point for choosing the right lens power for any reading distance.

Fact 01:

Wearing reading glasses does not make your eyes weaker. You don’t see with your eyes alone—you see with your brain. Once your brain experiences clear, comfortable vision, it simply adapts to that clarity.

Tip:

As you move reading glasses lower on your nose, the effective magnification increases. If you prefer wearing your readers low, choose your lens power with this in mind and consider selecting a slightly lower strength.

  • 25-30 years old start with +.50 - +.75
  • 30-40 years old +1.00
  • 45 years old +1.50
  • 50 years old +2.00
  • 60 years old +2.00 - +3.00

Where Do You Want To Use Your Reading Glasses

How far you view your reading material also determines your reading glasses lens strength.

Most Reading Distances Are:

-Traditional close reading distance (14–16 inches): Customary for books, hand‑held devices, and your desktop keyboard.

-Intermediate computer distance (18–20 inches): About an arm’s length—often where a laptop or the lower portion of your monitor sits.

-Typical computer distance (20–26 inches): Straight‑ahead viewing for a desktop screen.

Fact 02:

Scientific Principle: Focal power is inversely related to focal length. Which means, the farther away your reading material is, the less lens power you need to read it clearly. Move it closer, and you’ll need a higher lens strength for it to be sharp.

Tip:

Fine‑tune for sharpness by positioning your screen, seat, or reading material slightly closer or farther away.

Reading Glasses Eye Chart

Read this chart at the traditional reading distance of 14-16 inches. The first line you have difficulty reading is your suggested lens strength at that distance. For desktop computer reading at the typical viewing distance of 18 inches, reduce that lens strength by approximately half. The further away you view your screen, the less lens strength you will need to read it clearly and comfortably.

Tip:

Computer resolution differences require this chart be printed for accurate results. Actual sizing may vary depending on your computer settings.

Just A Few More Things

04

Reading Distance:

Reading at a computer screen 18” away will require a different lens power than reading at a screen that is 28” away or reading on your laptop, reading a book on your lap or reading papers on your desk. Choosing your lens power specific to your reading distance will give you the best reading at that distance and it is an important part to eliminating your eyestrain. Many times different corrections are needed for different reading distances.
05

Wearing Distance:

Some people like to wear their readers down their nose so they can look over them to see the distance and also read up close, like when watching T.V. while reading a newspaper or iPad. If this sounds like you, choose from our reading glasses with extra-long temples so they stay on securely and with a smaller lens depth so you can see over them easily. Lens magnification increases as you move your readers away from your eyes, so adjust your lens strength slightly to compensate.
