“What are the advantages of having a wide diopter range in a single lens compared to multi-focal or progressive lenses?”

1-1 of 1 Answer

• The main advantage of having a wide diopter range in a single lens is the convenience of not having to choose a specific diopter strength. This makes it easier to find the right magnification for your needs, especially if your prescription is between two standard diopter strengths. Additionally, single-lens readers may provide a wider field of view and reduced distortion compared to multi-focal or progressive lenses.
