HOW IT WORKS

Three simple steps.

02

Print at actual size

Select US Letter and 100% / Actual size. Disable “Fit to page”, then check the printed 1-inch calibration line with a ruler.

03

Find a starting point

Use the printed sheet in good light. Read from the smallest line downwards, following the instructions below.

USING YOUR PRINTED CHART

Take a moment.
Read at your pace.

Keep the distance consistent and read without squinting. The first comfortably clear line suggests a strength to try.

Read the printed PDF, rather than this website: display size, zoom and device settings change the scale.

  1. Remove reading glasses. If you wear prescribed glasses or contacts, ask your eye-care professional about choosing readers.
  2. Position the sheet 12–14 inches (30–36 cm) from your eyes, in good light.
  3. Begin at the smallest text and continue down until you can comfortably read an entire line.
  4. Note the power beside that line. Try readers at that strength and check comfort at your usual reading distance.

A CLEARER CHOICE

Your questions, answered.

Does this chart give me a prescription?

No. It is an indicative guide for trying ready-made readers, and it has not been clinically validated. A comprehensive eye exam can assess the strength and correction you need.

Why do I need to print it?

Lettering must have a consistent physical size. Phones, monitor sizes and browser zoom change the scale. Print the PDF at 100% and verify its 1-inch line before reading.

What if none of the lines is clear?

Do not assume you need the highest power. Consult an eye-care professional, especially if one eye sees differently, you already use prescription lenses, or reading remains uncomfortable.

Can I use A4 paper?

The PDF is sized for US Letter. If your printer supports A4, keep the setting at 100% / Actual size and check that the entire page prints without clipping. The calibration line must still measure 1 inch (25.4 mm).

Will every SunRay style offer every power?

The chart includes thirteen guide values, but available powers depend on the product. Check the actual options on the product page before you order.

Are readers suitable for distance vision?

Single-focus readers are designed for close-up tasks. Different lens types have different uses; check the product description and consult an eye-care professional for your vision needs.

When close-up reading changes

Age-related changes in the eye’s focusing ability can make small text harder to read. Readers may help with close-up tasks, while an eye exam can identify other causes of blur.

Keep your eye health in view

A reading chart cannot check eye health or replace regular eye exams. If you notice a sudden change in your vision, seek prompt professional care.
