Having a magnification for your glasses that is too strong or too weak can cause eyestrain and potentially cause headaches or migraines among other issues. We have provided a chart below that will assist you in selecting which magnification will work best for you.
Directions on using the chart:
- Without any reader glasses, reading glasses or other eyewear on, start at the bottom line and read the phrase provided “If this line is difficult to read, use”.
- If you can read the line clearly, move up to the next line continuously until you can no longer read the line or have difficulty reading the line.
- Whichever line you are having difficulty reading, follow it to the right and select the magnification power it recommends you using.
Reading glasses are a great tool to assist in reading, however, our opinions expressed here are strictly educational and you should see a specialist before purchasing any reading glasses to ensure your eyes are in good health. The magnification chart above is to be used strictly as a guideline and may not be 100% accurate depending on the computer/ device you are using.
