This is how you find the right glasses strength for ready-made reading glasses.

You need reading glasses but don't want to go to the optician right away? No problem – with a few simple tricks, you can also find the right strength yourself. In this article, we will show you how to determine your vision strength for ready-made reading glasses and what to look for when buying.

What does the strength of reading glasses actually mean?

The strength of reading glasses is indicated in diopters (dpt) – positive values like +1.0 or +2.5 mean that the glasses sharpen near vision. The higher the value, the stronger the magnification. Reading glasses usually start at +1.0 dpt and go up to +3.5 dpt.

When is a ready-made reading glass suitable?

Ready-made reading glasses are ideal if you only have slight presbyopia and no other visual impairments like astigmatism or different values in both eyes. They provide a quick, practical solution – provided you choose the right strength.

This is how you find your suitable strength

1. Use a printed strength chart

Many manufacturers – including us at Hypreader – offer free reading test PDFs or printed cards on. With this table, you can calmly check at home which line you can still read without problems – and read off the appropriate value from it.

3. Consider your age as a rough guideline

 

Change	Average strength
40–45 years	+1.0 to +1.5 dpt
46–50 years	+1.5 to +2.0 dpt
51–55 years	+2.0 to +2.5 dpt
56–60 years	+2.5 to +3.0 dpt
over 60	+3.0 to +3.5 dpt

 

These values are only a guideline – what matters is how you feel when reading.

4. Do you have headaches or blurred vision?

Then the strength may be too high or too low. The right reading glasses provide a relaxed, clear image without effort. Or you may indeed have a different strength, or there may be astigmatism present.

Our recommendation: It's better to start with a weaker strength.

If you are wavering between two strengths, first choose the lower one. Your eye will adjust better, lighter corrections are possible – and you avoid unnecessary strain.

When is a visit to the optician advisable?

If you can't see clearly with any strength, your eyes are of different strengths, or you get headaches, a vision test with an optician or ophthalmologist is advisable. Even with existing visual impairments or astigmatism, you should opt for a custom-fitted pair of glasses.
