HOW TO CHOOSE THE CORRECT PRESCRIPTION LENS
Determine your eyesight and SPH values.
*See your ophthalmologist or nearest optometrist to have your SPH values measured properly.
Simple method for measuring your SPH value
Hold a book outstretched in your hands and move it towards your face. When your eyes can focus on the letters, stop and measure the distance (cm) from your eyes. Divide 100 by this distance, and you will get your nearsighted SPH value.
If the focus distance with the naked eye is 20cm, then the eye refraction rate is:
100 / 20 = 5 => -5.0
*A negative symbol is added for nearsightedness, so it is -5.0.
