People with myopia of -2 D and lower do not typically need to wear differentials (because with -2 D your distance till blur should be around 50 cm - far enough to see your screen with sufficient clarity). The exception | People with myopia of -2 D to -1.5 D and lower do not typically need to wear differentials (because with -2 D your distance till blur should be around 50 cm, and with -1.5 D 67 cm, far enough to see your screen with sufficient clarity). The exception is that if you have more than 1 diopter of cylinder correction you will likely need differentials to help manage directional blur. In this event you likely can reduce the cylinder correction by between .25 and .75 D and pair it with a reduction of up to 1.25 D in spherical strength for either little or no spherical (plano) correction. | ||

Below -1 D, unless your close-up distance is around 100cm, you might consider using [[plus lenses]] as a differential. EndMyopia used to specify that they be used for low myopia, but they now consider it is a last resort. | |||
