GUIDES-&-HOW-TO’S Find Your Reading Glasses Power

We've made it easy to figure out your reading magnification, also referred to as your reading power, if you're new to reading glasses and aren't sure where to start.

UsING a Printable Diopter Reading Test Card

If you're purchasing reading glasses online, you can use our printable diopter chart. With the printed sheet 14" away, attempt to read the top line without reading glasses. Continue down the chart until you find a line you can read clearly without your glasses on – this is the diopter (power/magnification) you need.

Test Various Reading Magnifications

Prescriptions for reading glasses increase by 0.25 diopters, such as +1.00, +1.25, +1.50, and so on. However, for simplicity, some diopter charts may increase by 0.50 or by the whole number. Start by trying on reading glasses in the power that your test results yielded. You'll want to test out several pairs that are both weaker and stronger than your test results. Narrow it down to two magnifications — both of which you see well with — and always choose the lower of the two powers.
