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 50cm - far enough to see your screen with sufficient clarity). The exception being that if you have more than 1 diopter of cylinder correction you will likely need differentials | 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 50cm - far enough to see your screen with sufficient clarity). The exception being 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 .75D and pair it with a reduction of up to 1.25D in spherical strength for either little or no spherical (plano) correction. | ||
