Simple method for measuring your SPH value:

1. Hold a book outstretched in your hands and move it towards your face.

2. When your eyes can focus on the letters, stop and measure the distance (cm) from your eyes.

3. Divide 100 by this distance, and you will get your nearsighted SPH value.

For example, If the focus distance with the naked eye is 20cm, then the eye refraction rate is

100 : 20 = 5 (-5.0)
