What are differentials?
Differentials are glasses for close up. They are not used as the primary stimulus to improve eyesight, rather they help relieve eye strain and prevent hyperopic defocus when using screens up close for long periods of time.
They are essential in preventing axial elongation and the worsening of myopia.
