Print the Readers.com diopter chart, hold it 14 inches away without glasses, and read down—the first clear line shows your strength (e.g., +1.50).

• 40-44: +1.00 to +1.25 for early blur on labels.
• 45-54: +1.50 to +2.00 for books, phones.
• 55+: +2.25 to +3.25+ for fine print.

• Blurry near vision; hold items arm's length to focus.​
• Eye strain or headaches after reading/screens.
• Needing brighter light for small text.​

Presbyopia starts around 40 as the eye lens stiffens—over 1 billion affected worldwide.
It's normal; readers fix it easily.

Diopters measure magnification: +1.00 (low) to +3.75+ (high), in 0.25 steps. Lower for general reading; higher for tiny details. Choose lowest clear strength to avoid strain.
