Single vision refers to correction of one field of vision, either for a significant distance, intermediate distance (computer), or items up close (near vision). Single vision has the same optical focal point or correction over the entire area of the lens. Hence, one can choose from a wide range of frames that vary in style and design, such as thin, angular ones or bold, oversized ones.
Presbyopia requires lenses which can correct both short and long sight. Bifocal or progressive lenses are used for correcting presbyopic vision and these lenses are wider than single vision lenses. Thus, one needs to choose a bigger frame that is able to accommodate the size of the wider lenses.
