Indicative vision test

We’ve made a simple and indicative vision test to help you find the strength you need when buying reading glasses. You should sit 40 cm away from the computer screen - it's closer than you think.

Read the sentences below. When you reach the smallest sentence you can read quite clearly, you can read what strength you need in the right column.

If you are in doubt between two different strengths you should choose the lowest one.
